How to Remove Butyl Adhesive

How to Remove Butyl Adhesive

Butyl is a synthetic rubber used in many applications including as an adhesive product. When used on a tape it's used to join two butting or overlapping surfaces and left to set. Once dry it remains elastic and is water-resistant. Butyl tape is used in car windshields, roofing, boats, on PVC piping and to many other purposes. The only drawback is that it doesn't remove cleanly, often leaving behind dried or slightly elastic pieces of adhesive.

Instructions

    1

    Scrap up the surface tape with a putty knife. Pull the tape up slowly and get as much adhesive as you can while removing.

    2

    Cover the remaining adhesive with adhesive remover or paint thinner, such as Toulene. Allow the product to sit for several minutes.

    3

    Scrape up the softened adhesive with the putty knife. Repeat step two as needed.

    4

    Clean the adhesive free surface with a water soaked cloth. Allow to dry.

How to Adjust the Parking Brake on a 1998 Explorer

How to Adjust the Parking Brake on a 1998 Explorer

You can adjust the parking brake on your 1998 Ford Explorer right from your home driveway or garage, saving yourself time and money. You will know it's time for an adjustment when you find the vehicle slipping forward after you have engaged the parking brake when it is parked downhill. You need only a few tools purchased from your local auto parts retailer. If you normally do your own repairs, you probably already have these tools on hand. The only additional tool you may not have that you need is a cable tension gauge.

Instructions

    1

    Engage the parking brake by pressing it to the floor with your foot.

    2

    Put two wheel chocks in front of the front wheels and two behind them. Raise the rear of the vehicle up with a floor jack, slide two jack stands underneath the Explorer's rear frame rails near each rear wheel, then lower the Explorer onto the stands.

    3

    Get under the Explorer and hold the parking brake cable rod in place with your hand. You can recognize it as the rod in the center of the underside of the vehicle that has cables coming toward it. Tighten the equalizer nut with your pliers six turns.

    4

    Find the equalizers at the rear drums inside the wheel wells. Put the cable tension gauge behind the equalizers and set the tension up to 600 pounds max.

    5

    Ensure that the rear wheels won't spin. Then disengage the parking brake and check to see that the rear wheels spin easily and freely. If not, repeat the adjustment.

    6

    Raise the vehicle, remove the jack stands, lower the vehicle, and remove the wheel chocks.

How to Install a 1964 Dodge Windshield

Damaged windshields are not only cosmetically degrading, they are potentially dangerous, and may prevent your car from being legally roadworthy. Dodge produced several vehicle models in 1964, but they all use the same basic windshield system. This task is most commonly performed by a professional, but with some special tools you can do it yourself. Considering the weight and fragility of the windshield, this is a job that will require the assistance of a second person.

Instructions

    1

    Put on safety glasses. Make sure they cover the entire eye and leave no gaps for stray glass particles to enter. It's possible for glass to shatter during the removal process, and unprotected eyes are vulnerable to injury.

    2

    Slide a windshield trim removal tool between the glass and the surrounding trim. Gently maneuver the tool along the length of the trim until you feel it hit a clip. Carefully twist the tool side-to-side until the clip pops out. Continue this process along the entire perimeter of the windshield until all of the clips have been disengaged. Set the trim aside.

    3

    Cut the seal that runs around the outside of the windshield. This is a thick, black, rubber piece that was previously hidden by the trim pieces. A windshield seal cutter is ideal for this job, however a carpet knife will also work. Place the tool flat against the windshield and press against the seal to cut through it. Continue until the entire seal has been severed and the glass is completely exposed.

    4

    Slide a plastic windshield stick in between the glass and the frame, and gently work the glass free from the remaining part of the seal. Never substitute a metal tool for a windshield stick.

    5

    Push the windshield out from the inside of the car and remove it. Take care not to scratch the paint on the hood. Using a rag, clean the surface of any glue or sealant that remains.

    6

    Slide the new rubber seal over the new windshield. Slide the pull rope into the seal's channel. If your seal didn't come with a pull rope, you can substitute a length of nylon clothesline. This rope will be used to pull the seal into place once the windshield is on the car. Align the rope so that the excess length hangs out of the bottom of the seal.

    7

    Place the windshield on the car. Push the bottom part of the seal over the pinch weld. Pull the rope out of the seal. As the rope comes out, the seal will slide over the pinch weld, locking the windshield in place. Go slow around each of the corners to avoid damaging the seal.

    8

    Place a non-hardening sealer inside a caulk gun and, from the outside of the car, fill in the gap between the seal and the surrounding metal. This will help keep moisture out. Allow the sealer to dry, then replace the trim. Using mild pressure, the trim will simply snap into place once the clips are properly aligned.

How to the Adjust Rear Brakes on a 1996 Chevrolet 3500

How to the Adjust Rear Brakes on a 1996 Chevrolet 3500

The 1996 Chevrolet C/K 3500 came equipped with standard four-wheel anti-lock brakes. While the front brakes were ventilated discs, the rear brakes were drum brakes with a 13-inch drum inner diameter. Based on its gross weight ratio of between 9,000 to 12,000 pounds, the brake drums were either 2 1/2-inches or 3 1/2-inches deep.

Instructions

    1

    Lift the rear of the truck by the rear axle housing. Set jack stands beneath both ends of the axles, just behind the wheels. Remove both rear wheels with a wheel lug wrench by removing the lug nuts, and then the wheels.

    2

    Remove one brake drum from the hub with your hands. If the brake drum is seized onto the hub, gently tap the front of the drum near each lug stem. Tap the sides of the drum as well. The vibration of the hammer against the drum should loosen any corrosion or rust which may be holding the drum on.

    3

    Spray the entire drum brake assembly down with aerosol brake cleaner. The cleaner will remove excess brake dust and road debris, as well as clean up parts so you can see them better. Spray the inside of the brake drum one time all the way around to remove excess brake dust and road debris.

    4

    Use a flat-head screwdriver to push downward on the "star-wheel" adjuster, which is located at the bottom of the brake assembly. The "star-wheel" adjuster is a cylindrical object between the bottom of both brake shoes. When turned downward, the adjuster will expand and push the brake shoes outward.

    5

    Push the drum back onto the brake assembly. Ideally, the drum should provide some resistance, but not enough that you cannot push the drums on by hand. If the drums are too tight, then remove the drum and push the adjuster back upward about four to five clicks. If the drum slides on with no resistance, then remove the drum and push the adjuster downward four to five clicks. Repeat this step until the drum provides some resistance when installing. Install the drum back onto the rear brake assembly.

    6

    Repeat Steps 2 through 5 to complete the adjustment process on the second side of the truck.

    7

    Place the wheels back on and tighten the lug bolts down so that the wheel sits in its fully mounted position.

    8

    Turn the ignition key to the "2" position, or the accessories position, without starting the truck. Place the gear selector switch in "N" or neutral position. Spin each rear wheel by hand. Each tire should rotate approximately 1 1/2-rotations before stopping. If the wheel spins more than 1 1/2-rotations, then the brakes are under-adjusted. If the wheel and tire do not complete a full rotation, then the rear brakes are over-adjusted. Repeat Step 5 to loosen or tighten the brakes.

    9

    Tighten the lug nuts using a wheel lug wrench. Lower the vehicle. Tighten the lug nuts between 95 to 110 foot-pounds of torque.

Car Brake Facts

Car Brake Facts

A driver on the road is not always concerned with how his brakes work but that his brakes work. So is it important to know that breaks work by converting kinetic energy into thermal energy or that friction is used to cool the brakes and slow the car down? A little knowledge can go a long way, especially if you begin to have problems with the brakes.

Drum Brakes

    There are two types of drum brakes, single leading edge and double leading edge. Both types have two semicircular brake shoes that sit inside a spinning drum. The drum is attached to the wheel so that when the brake is applied, the shoe pushes out against the inside of the drum causing the heat and friction required to stop the car. The difference between the two is that a single leading edge makes contact with only one part of the drum and a double leading edge makes contact with two parts of the drum.

Disc Brakes

    Disc brakes contain two parts. Instead of a drum, there is a metal disc also known as a rotor. A caliper assembly replaces the brake shoes. Hydraulic pistons located within the caliper cause it to push against the back of the break pad. The break pad presses against the disc, which creates the friction necessary to stop the vehicle.

Full Contact Disc Brakes

    As technology advanced, a new type of disc brake was created. The idea behind this type of brake is that a standard disc brake only applies pressure to 15 percent of the rotor surface at any given time. With a full contact disc brake, five additional pads are used so that contact is made with 75 percent of the rotor's surface. This system is thought to cool the brake better, and make for a quieter and quicker stop.

Brake Squeals

    Oftentimes, a car will come to a stop and as pressure is applied to the brakes, they squeal. There can be a few reasons for that sound. The brake pads or the calipers may be loose or, more often, the squealing sound is caused by a lack of friction material.

Remedies

    Copper-based grease can be placed behind the brake pad to reduce squealing but care must be taken when this is done. If the grease gets onto the front of the pad, the brake pad and the rotor will need to be replaced because copper-based grease is resistant to heat and friction. If all the friction material is gone from the brake pad, it is time to get new brake pads installed. It could also be time for an alignment.

How to Repair a Honda Accord Side Window

How to Repair a Honda Accord Side Window

Although maintenance repairs for your Honda Accord may be infrequent, an unexpected repair such as a cracked side window can occur at any time. The causes can range from flying objects at high speeds to the glass window having a natural defect. If that should happen, take the time to fix the damage yourself with supplies purchased from any local auto store.

Instructions

    1

    Mix a cleaning solution with water and detergent. No measurements are necessary. Simply add enough detergent to the water in order to create a sudsy solution. Wash the window down, rinse it with water and then dry it off to start the repair with a clean surface.

    2

    Put on the goggles and remove pieces of broken glass from within the cracks if possible. Use the razor blade to pick the pieces out carefully.

    3

    Adhere the suction cup stabilizer to the window. Pressing on it firmly will give you the best suction between the two elements.

    4

    Place the resin tube into the injector, and then push the injector into its spot on the stabilizer.

    5

    Remove the injector once it is in place to allow for the resin to be drawn into the cracks.

    6

    Remove the suction cup from the window once the resin tube is emptied.

    7

    Cut a strip of adhesive curing film and place it over the entire repair. Remove the strip after a few hours of curing time. Once the resin has hardened, you can remove the strip.

How to Replace the Brake Rotors on a 1995 Ford Aspire

The disc brake system on your 1995 Ford Aspire uses a caliper and rotor system with brake pads. When you depress your brakes, the caliper clasps upon the rotor, which is a smooth round disc. This motion is what brings your Aspire to a stop. Driving with severely work brake pads can cause damage to your rotor. Jarring impacts or accidents can also damage your rotors, too. If this happens it is important to change the rotors as soon as possible.

Instructions

    1

    Remove tire tool and jack from your Aspire's trunk compartment. Loosen the lug nuts on the both front tires. Jack up your Aspire and set jack stands under its front frame. Take the lug nuts with the tire tool and remove both front tires.

    2

    Find the two brake caliper retaining bolts for the driver's side wheel. On your Aspire, they are located on the inside of the wheel hub. Use a 17mm socket to remove them.

    3

    Slide the caliper up and off the rotor. Hook a coat hanger to your Aspire's brake caliper and suspend it from the frame. This will keep you from breaking your brake line.

    4

    Remove the single screw from the inside of the hub that holds the rotor on. Use a Phillips screwdriver to do this. Slide the old rotor off and put the new rotor on. Replace the rotor screw. Also remove the coat hanger, set the caliper back in place and re-insert and tighten the caliper bolts.

    5

    Repeat steps 2 to 4 for to replace your Aspire's passenger side rotors.

    6

    Put both tires back and and tighten them down with the lug nuts and tire tool. Lift your Aspire some, remove the jack stands and then lower it and remove the jack.

How to Repair a Jeep Cherokee Window

How to Repair a Jeep Cherokee Window

Taking on a car repair job can be scary, but not if it's an easy one, like repairing a window. If your Jeep Cherokee has a cracked window, for instance, all you need are some supplies and free time. You do not need to be a professional, nor do you need to hire a professional to get the job done.

Instructions

    1

    Clean the window entirely with a soapy water solution. Use the soft cloths to wash and dry the glass.

    2

    Use the corner of the razor blade to dig out any pieces of glass that are stuck within the cracks. Put your goggles on for this procedure.

    3

    Attach the suction stabilizer to the window. Push down on it so the suction cup firmly sticks to the window glass.

    4

    Place the resin tube in the injector, put the injector into its port within the stabilizer and then remove only the injector. This will leave the resin tube inside the stabilizer, and the suction will quickly draw all of the resin from the tube into the crack.

    5

    Lift the stabilizer off the window gently. Place a strip of curing film over the repair. Once dried, remove the strip.

How to Replace a Front Windshield

Windshields only need to be replaced when there is damage that is sufficient enough to impair your vision when driving. Modern windshields are held in place by a powerful, yet flexible, urethane molding. Once the molding cures, it will flex, but not allow the windshield to crack under normal driving conditions. The Windshield itself is made of tempered glass. Even if you did get into an auto collision, the glass is designed to break into small pieces to avoid cutting you. However, even a good design is no match for a well-placed stone or a full-on collision. Stone chips are very common and can lead to a compromise in the integrity of the windshield. If you develop a crack that is more than an inch in length, you should seriously consider replacing the front windshield.

Instructions

    1

    Pry the plastic trim molding away from the windshield using a flat-tip screwdriver. Depending on the vehicle, this may or may not require a lot of time. Some vehicles use extensive trim around the windshield, others have no trim and instead use rubber molding. This molding will have to be cut out or carefully pulled out using the screwdriver.

    2

    Cut the urethane molding and break the seal holding the windshield to the vehicle. This molding is extremely tough, so it may take an hour or more to completely cut through all of this material.

    3

    Pull the windshield off and set it aside.

    4

    Scrape of residual molding on the vehicle down to 3 mm using a razor blade.

    5

    Clean off the vehicle's pinchweld where the new windshield will be installed. Use a brush and water to brush away any loose molding and debris. Then dry the area with a clean rag.

    6

    Apply the urethane primer to the frit band on the new windshield. The frit band is the black strip running around the perimeter of the new windshield. This band needs to be activated by the primer in order to adhere to the urethane.

    7

    Apply the urethane to the pinchweld area where the windshield will be placed. Use an electric caulk gun for better consistency in the application process. Use the 3 mm band of old urethane that is still in the pinchweld area of the frame as a guide to place the new urethane. It's OK to apply the new urethane over the old as long as it has been trimmed properly to 3 mm.

    8

    Align the windshield so that there is proper orientation on the frame. Align the top, bottom and sides of the windshield by sight as long as the frit band makes contact with the urethane.

How to Replace Crown Victoria Rear Brake Pads

Crown Victorias with rear disc brakes require rear brake pad replacement approximately every other time you replace the front pads. While there is no set mileage interval for brake replacement, it's best to inspect the brake pads every time you rotate the tires or every 10,000 miles, whichever comes first. Since the rear pads help control the sedan as it comes to a halt, while the fronts do most of the actual braking, you can see why the rears don't wear as quickly as the fronts. Anyone with basic auto-repair experience can replace Crown Victoria rear brakes in two hours.

Instructions

    1

    Position the wheel chocks in the front and back of the Crown Victoria's left-front tire to prevent the Ford from rolling. Turn all the Crown Victoria's rear lug nuts counterclockwise with your lug wrench to loosen them.

    2

    Pick the sedan's rear end up with the floor jack and support it on jack stands. Take the lug nuts off, followed by the rear wheels in order to expose the back disc brakes.

    3

    Place the drain pan under the left-rear brake rotor. Wash the Crown Victoria's left-rear brake caliper and rotor thoroughly with brake cleaner to remove the brake dust.

    4

    Remove the left-rear caliper bolts with a socket set. Lift the caliper from the mount by hand and then remove the old rear disc brake pads manually. Discard the pads.

    5

    Clean the inside of the left-rear caliper with brake cleaner. Grease the caliper slides with white lithium grease. Force the caliper pistons to retract using the caliper tool.

    6

    Insert the new rear disc brake pads manually. Slip the caliper back into the mount and bolt it in with your socket set.

    7

    Move around to the Crown Victoria's right-rear and repeat steps 3 through 6 to replace the right-rear brake pads.

    8

    Put the back tires and lug nuts back on the Crown Victoria by hand. Lower the sedan off the jack stands with the floor jack.

    9

    Torque the Crown Victoria's rear lug nuts to 85 foot-pounds with the torque wrench.

How to Fix a Honda Civic Front Passenger Window

How to Fix a Honda Civic Front Passenger Window

Fixing the front passenger window in your Honda Civic does not have to be a difficult task. If you inspect the damage and notice there is a crack that has traveled across the window, you can make the repair with few supplies and very little time. Purchase the tools needed from your local auto parts store and choose a warm, sunny day for the repair to help speed up the process.

Instructions

    1

    Mix water and detergent in bucket, then wash the window down. Dry it with a cloth or let it air dry completely.

    2

    Put the stabilizer on top of the cracked area. Push it down to create a suction between the glass window and the stabilizer.

    3

    Put the injector into the open injector site on the stabilizer. Then, put the resin tube into the injector.

    4

    Pull the injector out, and watch the suction of the stabilizer quickly draw the resin out of the tube and into the cracks.

    5

    Remove the stabilizer from the window once the crack, or cracks, have been filled.

    6

    Place the curing film strip over the repaired area, and allow one or two hours for the resin to cure and harden before removing the strip.

How to Repair a Cracked Plexiglass Windshield

How to Repair a Cracked Plexiglass Windshield

Car and boat windshields are often made of Plexiglas because it is an inexpensive and durable material. The biggest problem with Plexiglas is that if it cracks or scratches, the entire area around the crack or scratch becomes cloudy. Fixing a crack in the Plexiglas is the easiest thing to do yourself so you do not have to have a replacement windshield put in.

Instructions

    1

    Drill a fine, tiny hole at the end of the crack. If the crack stretches across the windshield, go to the tip of its reach and drill the tiny hole. This will prevent the crack from extending farther across the windshield. Remember, the hole should be small enough to round out the end of the crack's arm, but not large enough to break the windshield.

    2

    Fill the crack with Plexiglas adhesive. The adhesive will be as thin as water, so be careful not to use too much pressure when injecting it into the crack using an adhesive gun or injector. You can find the adhesive at most hardware stores. Wipe away any excess adhesive that spills outside of the crack onto the windshield.

    3

    Use the rotary polisher to buff and polish over the sealed crack. Place a foam buffer pad on the head of the polisher. Gently lay it flat against the crack, turn it on and use the lowest speed to start with until you get the hang of it. Move it in circular motions just enough to buff the sealed crack evenly against the rest of the Plexiglas windshield.

    4

    Pour a small amount of Plexiglas cleaner on a soft rag, and go over the entire windshield for a clean, transparent finish.

How to Get a Cheap Price for a Brake Job

Price for a brake job varies based on amount of work and type of car you own.
You must be careful when looking for a cheap brake job because you do not want to risk your brakes not working properly because you went for a cheaper price for the brake job.
Read the steps below to find out how to get cheap brake jobs while still guaranteeing that your brake job is done well.

Instructions

    1

    Understand that there are different levels of brake jobs. Price for brake job will depend on the extent of work necessary and parts that you need to buy. You may have to replace brake pads or shoes. You may have to resurface the rotors. You may need to replace the rotor. You may need brake fluid. There are a lot of types of mechanical work all termed "brake jobs".

    2

    Catch brake problem early on to avoid expensive brake jobs later on. If you hear a strange noise coming from your brakes or a strange feeling in your brake pedal, do yourself a favor and get it checked out right away. This could make the difference between a cheap brake job and a very expensive one.

    3

    Make sure your vehicle is inspected before you are given a brake job price quote. Without inspecting your vehicle, a mechanic has no way of knowing what type of brake job you need. He may just give you a higher quote assuming you need to replace extra parts that are really working fine. If possible, look for a mechanic that will give you a free inspection to save on the brake job cost. Get the brake job estimate in writing.

    4

    Don't be lured in by ads for brake job sales that end up costing you more. You may see a cheap brake job price quote written in an advertisement. There is a good chance the advertised price is the price of minimal brake work being done. If you need additional work it may cost you more than the average car mechanic may charge.

    5

    Ask questions when a mechanic describes the type of brake job work that needs to be done. Don't just go ahead with the mechanic replacing all your brake parts and doing extensive work without a justification.

    6

    Use cheaper parts. You may be able to buy cheap brake replacement parts. In some cases the cheap brake replacement parts may be all you need, but you should make sure they fit properly. If you trust your mechanic you can find out what type of cheap parts he is using and if they are good enough for your needs.

    7

    Use a mechanic that charges less per hour. The labor involved in fixing brakes makes up most of the cost of a brake job. If you can find a mechanic that is just as good but charges a few dollars less per hour and the job takes 3 hours to complete, the savings on the cost of the brake job may be substantial.

    8

    Be sure to get a warranty for brake job work to save money in the future on brake jobs. Find out what the warranty includes and get it in writing. Keep the warranty in case you have problems with your brakes in the future.

Auto Glass Installation Supplies

Auto Glass Installation Supplies

The purpose that glass serves in an automobile goes far beyond how it makes the car look. The glass serves as a barrier to the elements and insects. It is also a barrier for passengers who may be thrown out of the car. Properly installed glass supports the roof of a vehicle as protection in the event of a rollover accident. In addition, auto glass aids the accurate deployment of side air bags. Improper installation or poor-quality supplies could mean life or death to a vehicle owner.

Auto Glass

    There are three types of auto glass used for installation. Dealer auto glass is purchased directly from the automobile dealership. Dealer auto glass comes from an Original Equipment Manufacturer (OEM) distributor that originally manufactured the glass. This glass usually has the make of the vehicle stamped on it. OEM distributor glass does not always have the same distributor. but is made to the same specifications as dealer glass, such as thickness, color and durability. Lastly, aftermarket auto glass is made by companies that have not acquired the legal right to make the glass with OEM distributor specifications. Although it is cheaper, it is not accepted by dealers because it does not carry the same guarantees as OEM auto glass.

Windshield Urethane

    A high-quality urethane adhesive must be used so that the car bonds tightly to the auto glass. The U.S. Federal Motor Vehicle Standards requirements should be met or exceeded by the manufacturers of urethane used to install auto glass. OEM specifications must also be met with regard to urethane usage. In vehicles with aluminum bodies, such as late-model BMWs and Mercedes, low-conductive urethane is required in order to keep electrical currents from entering through the glass into the body of the vehicle.

Sealant

    A high-quality sealant is important in auto glass installation. Substandard sealants allow dust, air and water to enter the car. In addition, sealants which are inferior will become tough and eventually harden and crack, breaking the seal. Sealing compounds should create a superior bond between the glass, whether it is bonding to metal or rubber.

Instructions for Replacing a Windshield

Instructions for Replacing a Windshield

The windshield helps provide the overall structural integrity of most modern vehicles so proper installation of auto glass is essential for safety and reliability. Watertight urethane adhesive bonds the auto glass to the vehicle so they act together as a single unit to strengthen the auto body. The process of replacing a windshield is not difficult, and may be done at home with the appropriate tools and the proper procedure.

Instructions

    1

    Wear safety glasses and gloves at all times when working with auto glass. Cover the dashboard and seats in the passenger compartment with protective sheeting in case of broken glass. Remove the windshield wipers with a socket wrench, and the window moldings from around the windshield using a power drill screwdriver attachment. Also remove the hood cowl with a power screwdriver. The cowl is a rubber seal that acts a barrier against water getting into the vehicle behind the hood.

    2

    Cut any weather stripping with a windshield knife and pull it away from the glass. Lubricate the edge of the windshield, inside the vehicle and out, with lubrication aerosol. Cut away the urethane bead around the glass. The urethane bead is the original adhesive used to install the windshield. Insert the windshield knife between the auto body and the glass, and hold the knife so it remains in a vertical position while at the same time pulling toward you. Then go inside the vehicle and repeat, cutting the urethane bead with the windshield knife. If necessary, use a windshield pry to loosen the glass. Lift the glass out with a suction cup.

    3

    Prepare the new windshield for installation by cleaning the edges with acetone to remove any remaining dust or debris. Also clean the edge of the body panel where the glass comes into contact with the vehicle. This structure is called the flange. Apply primer to the edge of the glass and around the flange. Next, apply a new bead of urethane adhesive around the flange, a long continuous strip of adhesive that will spread and bond with the glass and the auto body. The amount of adhesive to apply is equal to the depth of the flange where the glass seats against the vehicle.

    4

    Set the glass over the urethane bead without delay. The urethane sets almost immediately. Lower the windshield in using a suction cup. Check for leaks around the windshield with water from a garden hose.

    5

    Replace the weather stripping around the exterior edge of the windshield if the vehicle had one. Insert the tab on the underside of the stripping into the gap between the glass and the vehicle, and remove the strip to expose the self-adhesive on the underside of the stripping. Reinstall the cowl, the windshield wipers and the moldings. Remove the plastic sheeting from the passenger compartment, clean the new windshield, and the vehicle is ready to drive.

How to Change the Brakes on a Chevy Aveo

The Chevrolet Aveo is a sub-compact automobile manufactured with a hydraulic master cylinder braking system, with rear drums on some models. The pads and shoes are routine replacement parts; rotors, drums, wheel cylinders, calipers and the power brake booster are all prone to failure if not maintained. The average backyard mechanic can change the brakes on the Aveo in about 20 minutes per brake.

Instructions

Changing the Brakes on a Chevrolet Aveo

    1

    Raise the car with the floor jack, and remove a wheel by turning the lug wrench in a counterclockwise direction. Set the wheel aside, away from the car. If starting on an early model Aveo with rear drum brakes, skip to step 6.

    2

    Remove the caliper by turning the rear mount bolts in a counterclockwise direction, then slide the caliper and pads off of the rotor. Take the pads from the caliper, then set the caliper on the upper control arm. Do not let the caliper dangle from the brake lines.

    3

    Remove the rotor by firmly pulling it from the hub. Replace with a fresh rotor, or resurface the existing unit, then press the rotor into place over the hub.

    4

    Replace the brake pads with new units by pressing them onto the caliper pistons. Slide the caliper over the rotor, then secure the mount bolts by turning them clockwise. Some calipers may be difficult to compress once expanded, but removal of the master cylinder cap will lower the pressure in the system enough to press them into place.

    5

    Replace the wheel by turning the lug nuts clockwise, in an alternating pattern; then lower the Aveo from the floor jack.

    6

    (Wheel removed.) Remove the drum keeper screw by turning it counterclockwise. The keeper screw is on the front of the drum, a bit off-center from the hub. Once free, the drum can be pulled off over the shoes.

    7

    Replace the shoes by relieving the long springs from the hooks on each shoe, then turn the center spring bolt in a counterclockwise direction. The new shoe is held in place with the spring bolt, then reattached to the long springs via the shoes hooks. Replace the new or refinished drum by sliding it over the shoes and turning the keeper screw clockwise.

    8

    Replace the wheel, if applicable, and lower the Aveo from the floor jack.

How do I Remove a Windshield From a '90 Chevrolet Astro Van?

How do I Remove a Windshield From a '90 Chevrolet Astro Van?

If you need to remove the windshield on your 1990 Chevrolet Astro Van but don't have the funds to get the work done professionally, do it yourself. You just need a few simple, inexpensive tools that you can purchase from any auto-parts store. The removal process is fairly quick. It's very important to remove and replace your windshield if it has a crack longer than 6 inches. A crack this long compromises the integrity of the windshield and you risk having the windshield shatter if the vehicle becomes involved in an accident.

Instructions

    1

    Twist and remove the retaining nuts from the windshield wipers using a wrench. Set the wipers aside.

    2

    Put on some work gloves to protect your hands. Pry off the rubber fitting using a pry tool and pull it away from the windshield with your hands. Discard or recycle the rubber fitting.

    3

    Run the wire under the windshield and all the way around it to break the urethane seal. Push out the Astro's windshield from inside the van.

    4

    Remove the windshield from the front of the van and recycle or discard it.

    5

    Scrape off the urethane bead from the Astro Van's windshield opening with a utility knife. Try to remove as much of the urethane as you can.

How to Replace the Rear Brake Shoes on a 2005 Chevrolet Silverado

How to Replace the Rear Brake Shoes on a 2005 Chevrolet Silverado

The procedure for removing and replacing the brake shoes on your 2005 Chevy Silverado truck depends on whether you have a 1500 model or a larger truck model. The Silverado 1500 uses different types of brake shoes from most other vehicles--it uses a singular, circular shoe that wraps around the brake actuator on each wheel. Larger trucks use a more standard form of brake shoes. In any case, you need to replace the brake shoes for both rear wheels at the same time.

Instructions

Instructions for 1500 Trucks

    1

    Raise the truck's rear end and support it on jack stands. Remove both rear wheels, but prepare to work on one brake assembly at a time.

    2

    Remove the brake caliper mounting bolts with a wrench (grip the slide pins with a second open-end wrench to keep them from sliding) and lift the caliper off. Unbolt and remove the mounting bracket and then slide the disc off the hub.

    3

    Remove the screw and clip, located near the bottom of the brake shoe, using a screwdriver.

    4

    Lift one of the brake shoe's top ends over the axle flange and wind the shoe around and off the flange.

    5

    Turn the adjuster screw at the top of the assembly with a screwdriver until the adjuster screw's slots and tappet are parallel with the backing plate.

    6

    Insert one end of the replacement shoes into one slot and tappet of the adjuster screw. Wrap the shoe over the axle flange to install it, then fit the shoe's other end on the adjuster screw.

    7

    Turn the adjuster screw until the brake lining begins to drag over the braking surface. Remove the disc and turn the screw in the other direction until the shoes don't drag any more.

    8

    Slide the brake disc back onto the hub and reconnect the caliper mounting bracket and caliper with their bolts. Reconnect the wheels and lower the truck after changing the shoes for both brakes.

Instructions for Larger Trucks

    9

    Raise the truck and remove the wheels, caliper and brake disc, as described in Section 1.

    10

    Push down on the brake shoe's hold-down clip with a flat-head screwdriver, and turn the clip 90 degrees to remove it.

    11

    Unhook the return springs from the top and bottom ends of each shoe using needle-nose pliers, then remove the shoes from the backing plate.

    12

    Install the replacement brake shoes onto the backing plate and connect the return springs with the pliers, followed by the hold-down clips.

    13

    Adjust the shoes with the adjuster screw, as described above.

    14

    Reconnect the brake disc, mounting bracket, brake caliper and wheels and then lower the truck.

Ford Explorer Rear Rotor Removal

Ford Explorer Rear Rotor Removal

Late-model Ford Explorer SUV's are manufactured with rear disc brakes, which have a caliper, rotor, and a drum-style parking brake incorporated into the rotor (as there are no cable-operated calipers). Any one of these parts can become damaged or wear out, requiring replacement. The average backyard mechanic can remove the rotor from an Explorer in about 20 minutes.

Preparation

    Access to the rear brakes requires the removal of the wheel. The truck can be lifted with a floor jack, then supported with a jack stand if necessary. The floor jack head and stand should be placed on a frame rail, not the body or suspension. Turn all lug nuts counterclockwise and the wheel should come off the hub. Set the wheel aside, and away from the work area.

Caliper

    Inspect the brake assembly for damage or wear. The caliper should not be leaking, and the rotor should be smooth and not pitted or scratched. Remove the rear bolts that hold the caliper to the brake assembly by turning them counterclockwise. When they are out, the caliper will slide from the rotor and can be secured to the control arm of the suspension or set there. The caliper should not be allowed to dangle from the brake lines. Check the pads for wear and material thickness.

Rotor

    Some models will have a keeper (or spindle) screw holding the rotor in place, which can be turned counterclockwise and removed. The rotor will slide out directly away from the brake assembly, and underneath it are the parking brake pads. The interior of the rotor is the drum surface of the parking brake. The rotor can now be resurfaced or replaced.

How to Reseal Dodge Van Windshields

Resealing Dodge van windshields needs to be done as soon as you notice a leak develop. Leaks can happen for a variety of reasons. The age of the vehicle often brings with it deterioration in the urethane sealer. The sealer adheres the windshield to the frame of the van. When the seal between the glass edge and the frame occurs, water will get inside the van when it rains.

Instructions

    1

    Run water over the windshield to determine where the leak is. Make a note of the area where water is leaking in through the windshield.

    2

    Pry up the window molding using a trim removal tool. Wedge the tip of the tool underneath the molding where the leak is and pry up on the molding.

    3

    Apply a bead of urethane caulk to the glass edge to reseal the glass to the windshield.

    4

    Press the window molding back against the urethane and glass. Allow the urethane to cure for 24 hours.

How to Remove a Stuck Brake Rotor From a Chevy Silverado

Perhaps you were hoping for a simple brake repair procedure on your Chevy Silverado. That was before you tried to remove the rotor, but it's rusted stuck to the hub. There are still a few tricks you can try before giving up, and chances are, you'll be successful. Perseverance and diligence will pay dividends, and some specialty tools might help as well.

Instructions

    1

    Determine if you're saving the rotor--the farther into this procedure you get without success, the less the chance of reusing the stuck rotor. If you're planning on reusing it, start with the lowest impact removal procedures. Depending on how stuck it is, you'll have to consider replacing it if you're not successful.

    2

    Spray the hub center of the rotor and the back side of the rotor liberally with spray lubricant. Allow the lubricant a few minutes to soak in. Strike the rotor with force using the rubber mallet. Put on the safety glasses and strike the rotor on the plated fins from the backside of the rotor hitting outward. Turn the rotor 1/4 turn after a couple of strikes to change the position of shocking it from the hub.

    3

    Apply the three-stem puller to the front of the rotor. The stems will grip the rotor from behind the plate, and as you tighten the center adjuster, the shaft will sink and pull the rotor from the hub. Generally, this is a successful way to remove the rotor with the intent to reuse it.

    4

    Use a slide hammer with a rotor/drum removal adapter screwed onto the end. Much like rotating the rotor 1/4 turn when striking it with the rubber mallet, you want to position the slide hammer on different striking points of the rotor to finally break it free from the hub.

    5

    Light the torch and heat the hub of the rotor on the edges and in front by the lug studs. The heat may loosen the rust, and then you can try any of steps from Step 2 to Step 4 if you still want to reuse the rotor. Once you've exhausted all of these procedures without success, it's time to throw in the towel and forget about reusing the rotor. Too much force will be required to remove it from the hub, and it will be damaged, but you can still remove it.

    6

    Strike the plated fin of the rotor again using the 2 lb. sledgehammer. Again turn the rotor 1/4 turn between every couple of strikes. Relight the torch at this juncture and strike the rotor again using the sledgehammer.

    7

    Unpack the big guns and use the pneumatic impact hammer with a flat stud removal bit to start. Loosen up the rust by using the hammer to strike the flat of the hub near the lug studs, but be careful not to hit the lug studs accidentally. Use a blunt rounded tip with the impact hammer and strike the rotor from behind outward, being careful of the backing plate, and again turn the rotor manually 1/4 turn after a few seconds of striking. Being the last resort, you will definitely be successful with this procedure, provided you have a quality-brand impact hammer.

    8

    Clean the surface of the hub with a die grinder and a coarse reconditioning disc. Clean along the edges of the hub where the rotor seats against the hub. Apply a light coat of anti-seize lubricant to the edge of the hub and the center of the hub where the center hole of the rotor sits against. This will help you on future removal procedures of the rotor.

How to Install Windshield Rubber

The rubber molding that surrounds a windshield protects the glass edge and helps prevent dirt and debris from working their way into the urethane sealant once the windshield is installed. To install the windshield rubber on most vehicles, however, you must have the windshield off the vehicle. This means that, normally, when you replace the windshield molding, you have to reseal the windshield. Once the windshield is off the vehicle, installing the rubber is relatively easy.

Instructions

    1

    Orient the rubber molding so that the recessed groove is facing the glass edge.

    2

    Press the rubber molding over the edge of the glass. Make sure that the glass edge is fully inserted into the groove on the rubber.

    3

    Work the rubber around the entire edge of the windshield glass until the glass edge is fully protected.

How to Fix Scratches in Auto Glass

The windows of your car are constantly exposed to harsh weather, road debris and other elements of nature, causing an inevitable wear and tear to the glass. Some of these scratches may appear to be irreversible, but many of them can be repaired without seeking professional service. All it takes is a small investment and some extra time to treat auto glass scratches yourself.

Instructions

    1

    Determine the type of scratch you need to repair. Your fingernail should run smoothly across it if it's a surface scratch. These are entirely repairable with the proper materials. Scratches that catch your nail when running across them however are too deep to for simple repair. Deep scratches require that you have the entire window or windshield professionally replaced.

    2

    Purchase a glass or windshield repair kit from your local auto supply shop. Permatex, Stoner and Windshield Pro are some of the most popular and affordable makers of this product. Each kit includes a rubbing compound that will be the solution to your auto glass scratches.

    3

    Prepare the damaged glass by cleaning it with car wash soap and water. Distilled water is recommended in order to avoid contaminants such as grit and chemicals commonly found in hose water. The water is meant to simultaneously wash away the abraded glass and keep the area cool. Heated glass may become distorted, perhaps making scratches worse. For this reason you should also avoid repairing the scratches in direct sunlight.

    4

    Rinse the glass thoroughly and dry it with a microfiber towel to ensure that you've wiped away all traces of dirt. Once the area is completely dry, apply rubbing compound to the scratch according to the recommended amount indicated on the package. Some require you to apply it with a clean cloth, while other brands are safe to apply with your hands.

    5

    Allow the compound to settle for the appropriate amount of time before buffing the area. You can choose to use a terry cloth to buff it by hand, but a small rotary buffer like the Ryobi 10" orbital buffer is much more efficient. It allows you to spread the paste quickly and thoroughly without applying too much pressure. Once you have treated the scratch as instructed, wipe away the remainder of the rubbing compound and verify that there are no signs of damage to the glass. If a scratch persists, repeat the process as needed.

How to Install Rotors on a 2005 Pontiac GXP

The brake rotors on the 2005 Pontiac GXP are the component that the brakes grab onto to bring the vehicle to a stop. The brake rotors sit on the hub assembly with the brake caliper slid over the top of the brake rotor. Every time the brakes are applied, the brake pads are compressed inward onto the brake rotor. Once the brake pads are applied to the brake rotor, the vehicle begins to slow down until it stops.

Instructions

    1

    Park the 2005 Pontiac GXP on a level even surface and set the emergency brake.

    2

    Jack the front of the car up and place the jack stands behind each front tire under the frame rail of the car. Lower the car onto the jack stands. Make sure that the jack stands are securely underneath the cars frame rail.

    3

    Move to the side of the car where you want to install the new rotor. Remove the tire with a lug wrench. Turn the lug nuts counter-clockwise to loosen and remove the lug nuts. Pull the tire off and set it to the side.

    4

    Remove the two allen head bolts that hold the brake caliper in place over the brake rotor. Then slide a flat head screwdriver in between the brake caliper piston and the brake pad. Pry the brake pad forward to make room for the brake caliper to slide off of the brake rotor.

    5

    Slide the brake caliper straight off of the top of the brake rotor. Do not let the brake caliper hang from the brake line. Position the brake caliper so that it is sitting on the front strut or axle.

    6

    Slide the brake rotor off of the hub assembly. The brake rotor on the 2005 Pontiac GXP is not attached to anything and will slide straight off.

    7

    Line the holes up on the new brake rotor and slide the new rotor onto the lugs until it stops. Slide the brake caliper back over the brake rotor and insert the brake caliper bolts back in place and tighten down.

    8

    Put the tire back on and tighten the lug nuts down very tight. Jack the car up and remove the jack stands. Lower the car to the ground.

    9

    Crank the engine and pump the brakes a couple of times to set the brakes to the new brake rotor.

How to Replace the Door Glass on a Camaro

Replacing the door glass on a Camaro is necessary if the glass is chipped or broken. You can expect this project to take the better part of a day. When you replace the door glass, it is a good idea to prop the door open using a cinder block or large brick. This eliminates having to struggle with keeping the door open while dealing with the glass and other parts of the door.

Instructions

    1

    Remove the window crank using a horseshoe-clip removing tool. Place the tool between the crank and the door. Toggle it until the clip comes out. Slide the crank off its shaft.

    2

    Unscrew the armrest and the door lock knob. On some models, there may be other screws inside the door pulls. Disengage the circlip from the door latch pull rod. Remove these items.

    3

    Take off the small metal clips from the edges of the trim panel using a tack puller. Use this tool to remove the "Christmas tree" plastic clips without damaging the hardboard backing on the trim panel. Lift the door trim panel straight up. It should come out easily. Check the condition of the inboard door felt and the tar-paper water seal, and replace them if needed.

    4

    Remove the outer window felt using an offset screwdriver. Take out the plastic rivets, if any, using needle-nose pliers.

    5

    Unbolt the two stabilizers atop the door. You also have to remove the lower and upper stops to get the glass out. To remove the front upper stop and rear upper stop, crank the window to three-quarters of the way down. To remove the stop bolts that are in slotted channels, remove the front and rear lower sash channel nuts.

    6

    Back out the adjustment of the front and rear upper guide bolts that control the in-out tilt adjustment, and carefully lift the old glass out.

    7

    Put in the new glass. Swap the hardware that is in the old glass to the new one using common hex bolts. To transfer the forward bell crank assembly that is retained in the old glass with special two-hole nuts to the new glass, a homemade two-pronged tool or Snap-on S9610 is needed.

    8

    Loosen the star-shaped plastic guide that helped the old glass from rubbing in the track and snap it on to the new glass. This can be done using only your hands. Wiggle it back and forth and lower the new glass into position.

    9

    Bolt the front and rear sash channel nuts to the glass and reinstall all the other mechanisms in the door.

How to Fix a Spider-Web Crack in a Windshield

A spider-web crack on your windshield consists of a midpoint with smaller cracks branching out of it. This can be a difficult type of crack to fix; however, depending on the thickness of the crack, its size and whether there are any air pockets in it, you may still be able to reduce the spider-web crack's visibility, if not eliminate it. Visit your local auto shop to purchase an injectable crack filler. Most fillers include all the necessary tools for the job.

Instructions

    1

    Hold a rag over the opening of a can of acetone. Turn the can over to dampen that section of the rag with acetone. Lightly wipe the damp rag over the spider-web crack to clean the affected area of the windshield. Allow the windshield to fully dry.

    2

    Peel off the supplied adhesive strip's paper backing. Center the strip over the spider-web crack. Rub it firmly onto the windshield with your fingernail, then peel off the paper backing on the side facing up.

    3

    Place the supplied fitting onto the adhesive and use your fingernail to rub it in place. Adjust the fitting so it sticks as straight up as possible.

    4

    Remove the resin syringe's cover and insert the tip into the fitting. Hold onto the syringe with one hand and pull the syringe's handle all the way up with the other hand. This creates a vacuum seal between the adhesive strip and fitting and sucks any air bubbles out of the spider-web crack. Wait for about 1 minute.

    5

    Let go of the syringe's handle. The pressure from the vacuum will pull the handle down and shoot resin into the spider-web crack. Pull the handle back up and wait another minute before letting it go again. Repeat an additional four or five times to ensure you filled as much of the spider-web crack with resin as possible.

    6

    Pull the syringe out of the fitting and gently peel both the fitting and adhesive strip off the windshield. Allow the resin to cure according to the manufacturer's directions. Use a bit of rubbing alcohol to remove any adhesive stuck to the windshield.

How to Replace the Side View Mirror on a Honda S2000

Introduced in April, the 1999 Honda S2000 represented the 50th anniversary of the Honda Motor Corporation in grand roadster style. Although the Honda S2000 is a high power sports car, Honda equipped it with standard side view mirrors. The mirror shells are shaped to resemble the art deco mirrors of the late 1960s and attach to the vehicle in the same manner as most convertible vehicles. They bolt into the side of the door.

Instructions

    1

    Remove the inner door panel by using a Phillips screwdriver to remove the five Phillips screws that secure it to the door frame. With the screws removed, pull the panel off the door. The panel has additional tabs hooked to it that press fit into the door. Take caution not to break the tabs while you pull the panel off.

    2

    Roll the window up to allow access to the back side of the door.

    3

    Disconnect the wiring harness from the mirror by pulling the locking tab on the harness upward and then pull the two ends apart.

    4

    Remove the two 12 mm bolts that secure the mirror to the door. Hold the mirror with one hand while you remove the bolts with the other.

    5

    Place the new mirror against the door and bolt it into place.

    6

    Reconnect the wiring harness. Press the locking tab down to prevent the harness from working loose over time.

    7

    Line the tabs on the door panel up with the holes in the door frame and press them into the holes.

    8

    Screw the door panel into place with the five screws.

How to Replace a Cracked Windshield

Windshields are secured to the frame of your vehicle using a strong but flexible urethane sealant. This type of molding or sealant is necessary because of the abuse a windshield typically gets from the elements. Even so, no windshield can withstand a crack. Cracks can start as a stone chip or an actual fracture. Eventually it will spread across the entire windshield until the glass breaks. You should replace the windshield before this happens, but you'll need to know how to replace a cracked windshield first.

Instructions

    1

    Pry the plastic trim molding off the windshield using a windshield molding removal tool.

    2

    Remove the urethane molding with an automotive cutting knife designed to cut urethane molding. These can be found at most auto parts stores.

    3

    Pull the old windshield off.

    4

    Clean the remaining urethane residue from the windshield with a cleaning brush and water and trim the molding back to 3 mm with a razor blade.

    5

    Clean the pinch weld area around the perimeter of the frame where the new windshield will go. The pinch weld area is the recess running around the windshield where the new windshield and molding fits onto the frame.

    6

    Fit the new rubber molding around the outer edge of the windshield and fit the outer trim into the grooves on the rubber trim.

    7

    Apply urethane primer to the frit band on the windshield. The frit band is the black strip running around the edge of the windshield. When you apply the primer to this, it activates the pores on the frit band coating, allowing it to adhere to the urethane.

    8

    Apply a bead of urethane to the pinch weld area on the frame of the vehicle.

    9

    Align the top, bottom and sides of the windshield on the frame and press the windshield into place.

How to Replace a Caliper in a Honda Prelude

The brakes in your Honda Prelude are among the most important parts of the vehicle. If something like the calipers must be replaced, it should be in the hands of an expert. Talk with your mechanic before attempting to change any major part on your Prelude.

Instructions

Removal

    1

    Siphon about half the brake fluid out of the master cylinder reservoir. Don't allow the reservoir to empty to prevent as little air as possible to enter the system.

    2

    Raise and support the vehicle safely on the jack stand. Remove the tire and wheel assembly.

    3

    Unfasten the caliper's mounting bolts. Remove the caliper assembly from the rotor/bracket, pivoting it upward and sliding it off the pin.

    4

    Disconnect the brake hose from the caliper and plug the hose to prevent losing or contaminating the fluid. Don't let the caliper hang from the hose while doing this.

    5

    Remove the bolts on the caliper mounting bracket and remove the bracket from the rotor.

Installation

    6

    See that the new caliper's piston is completely bottomed in the bore. Retract the piston into the caliper with a C-clamp if necessary.

    7

    Clean the both steering knuckle abutments/support brackets. Run a mist of water over them and wipe with a damp towel. Lubricate them with a coating of multi-purpose grease.

    8

    Reinstall the caliper bracket and secure the mounting bolts. Position the caliper and brake pad assembly over the brake rotor.

    9

    Install the assembly into the steering knuckle or support bracket abutments. Make sure that the guide pin bolts, rubber bushings and sleeves are clear of the steering knuckle bosses.

    10

    Reconnect the brake hose, using new washers with the bolt. Fill the master cylinder with fresh fluid and bleed the brake system.

    11

    Attach the wheel and tire assembly back on. Lower the vehicle and tighten the lug nuts.

    12

    Press the brake pedal in two inch strokes, about three to four times, until the brake linings are seated and firm. Don't road test the vehicle until the brakes feel firm.

Do it Yourself Windshield Chip Repair

Do it Yourself Windshield Chip Repair

One minute you're gazing through a clear windshield, then: Ping! You cringe as a chip ruins your view. One chip may not seem like much, but left alone, it could spread to a crack and you could eventually end up having to replace the whole windshield. You could take your car to an auto glass shop and have them fix the chip, but with a do-it-yourself kit and less than an hour of time, you could make the repair yourself.

Repair kits

    There are two types of auto-glass chip repair kits. The least expensive includes a syringe and a special resin. That type of kit is intended for one-time use and contains enough resin to repair one chip. Slightly more expensive kits include the resin and a plastic bridge. You can buy refills of resin for those kits and use them over and over.

    You can repair chips or pits of up to an inch in diameter with these kits. They aren't intended for cracks, spidering or starred chips. Repairs work best when done as soon as possible. The resin may not adhere to old cracks.

Clean the Windshield

    Clean the windshield thoroughly with glass cleaner and allow it to dry. If there's any dirt in the chip itself, you can use a safety pin or bent paper clip to clean it out.

    Spread out an old towel or rag on the hood below the chip to catch any resin drips.

Inject the Resin

    Your kit should contain a small adhesive disk and a plastic pedestal. Adhere the pedestal to the windshield with the adhesive disk, centering it over the chip. Remove the cap from the syringe and seat the syringe firmly in the pedestal. Pull back on the plunger and hold for a few seconds, then let go. That helps pull air out of the chip, and when you release the plunger it forces resin into the chip. Repeat that 10 times.

Inspect the Repair

    Check from inside the car to see if there are any air bubbles. If so, you may need to repeat the plunging process some more.

    The resin will cure in about a half hour. After the resin has cured, remove the syringe and the pedestal. You can scrape the pedestal off with a razor blade.

    Some kits include an additional step for applying a curing film. Follow the directions on the box for that step.

What Is a Metal Oxide Windshield?

What Is a Metal Oxide Windshield?

Car windshields have improved greatly since the introduction of the first safety glass versions in 1905. Windshields containing metal oxides provide an electrical de-icing option or a heat reflecting capability.

History

    The first windshields containing metal oxides appeared in the late 1980s and were installed on certain cars (usually more expensive models) throughout the 1990s and into the 2000s.

Metal Oxides

    A metal oxide is a combination of a metal and oxygen. Oxides of tin, zinc, and/or indium are used in windshields.

Metal Oxide Heating Elements

    Electrically conductive transparent metal oxide films incorporated in a windshield are used to heat the windshield for de-icing.

Metal Oxide Reflectivity

    A thin coating of silver is used in some windshields to reflect infrared and ultraviolet rays. Metal oxides are used in these windshields to protect the silver coating and to reduce reflections of other rays.

Drawbacks

    Windshields containing metal oxide particles can interfere with radio signals. Vehicles equipped with tollway auto-pass systems will often require an externally mounted transceiver if they have a metal oxide windshield.

How to Repair the Brake Line on a Ford Aspire

How to Repair the Brake Line on a Ford Aspire

The brake lines on your Ford Aspire are designed to withstand the tremendous internal hydraulic pressure exerted on them by the brake master cylinder when the brakes are applied. Whether you are dealing with a damaged rubber line leading to a caliper or the steel lines running fluid back and forth from the master cylinder, a damaged brake line must be addressed immediately. Loss of brake pressure due to a failed line can translate to a loss of brakes altogether. Not being able to go is one issue; not being able to stop is a much larger problem.

Instructions

    1

    Use the box wrench to unbolt the damaged brake line at both ends.

    2

    Compare it to the replacement line to make sure the two match up at each bend and in overall length. If you could not purchase an exact replacement line, but had to purchase bulk line instead, move to Step 3. Otherwise, skip to Step 4.

    3

    Take the bulk brake line and fish it through the brake line bender and bend it in each position until it is an exact duplicate of the old brake line. Consult the brake line bender's instruction guide for tool usage. Use patience and care when bending the line, as it can be snapped easily.

    4

    Position the new line in place and tighten down the fittings with the box wrench. Make sure the fittings are flush with the connection when done, but do not overtighten them.

    5

    Top the master cylinder with fresh brake fluid. Make sure not to let the master cylinder sit open for more than the few seconds it takes to fill it with fluid.

    6

    Get a helper to pump the brake pedal several times and then hold it down while you open the brake bleeder screw and release the air. Close the bleeder screw when fluid begins to come out. Repeat this step at all four wheels until no air escapes when the bleeder screw is opened and nothing but clean brake fluid escapes. This will bleed any air out of the system and flush the old, contaminated fluid out as well. Make sure all the bleeder screws are closed when done. When finished, your helper should experience a firm brake pedal that does not sink when applied.

How to Realign a Car's Power Window

How to Realign a Car's Power Window

If the window in your vehicle goes out of alignment it can cause the power window function to no longer work correctly. The most likely cause of the problem is the window not being correctly secured to the window regulator. If you cannot securely close your window it can put your vehicle at risk of being stolen. To solve this problem you need to disconnect the window from the regulator and reattach it correctly.

Instructions

    1

    Open up the door which contains the window which will not work correctly. Use a flat head screwdriver to pry open the automatic window control box, which is in between the two front seats.

    2

    Unhook the electrical connector inside the control box with your hand to prevent power going to the window regulator. Remove the mounting screws on the inner door panel of the door using a phillips-head screwdriver.

    3

    Remove the door panel from the door. Locate the screws attached to the door handle trim. Pull the trim and the door handle away from the door. Unhook the two linkage arms from inside the door with your hands and remove them from the door. This will give you better access to the window regulator.

    4

    Lower the window regulator to its lowest possible position within the door access panel. Use a hex wrench to remove the hex bolts which connect the window to the regulator. Lift the window away from the regulator.

    5

    Align the window with the regulator correctly so that the holes of the regulator line up perfectly with those on the window. Fix them in place by reattaching the hex bolts. Reconnect the rest of the door assembly by following the removal steps in reverse.

How to Remove a Vacuum Booster from a 1999 Olds 88

Older cars use a master cylinder by itself to provide the hydraulic power to operate the brakes on the car. The problem was, mashing the brake took a lot of strength that not everyone had. As a result, the vacuum brake booster was created to add a vacuum assist to the pedal. If the vacuum booster on your 1999 Olds 88 develops a vacuum leak, then your 88's brake pedal will become very heavy and you'll need to change out the booster to make braking as easy as it's supposed to be.

Instructions

    1

    Open the hood. Unbolt the master cylinder from the brake booster using an open-end wrench, then pull the master cylinder off the booster. The booster will be supported by the brake lines, so try not to distort them in the process of removing the unit. Then unplug the vacuum hose leading to the booster, using your hands.

    2

    Crawl underneath the dashboard and follow the brake pedal up under the dash until you see the connection to the master cylinder. Unbolt the connection at the pedal, using an open-end wrench and the ratchet. Then remove the acoustic panel that the master cylinder rod goes through to reveal the nuts holding the booster in place on the firewall.

    3

    Unbolt the brake booster from the firewall, using the 3/8-inch ratchet, extension and sockets. You may need to use a universal joint to gain access to certain bolts depending on the size of your hands and the depth of your sockets.

    4

    Go under the hood again and pull the brake booster off the firewall.

How to Replace a Brake Switch

How to Replace a Brake Switch

The brake light switch activates the stoplights on your vehicle every time you depress the brake pedal. However, a worn out or damaged switch may keep your brake lights permanently on (if the switch cannot open any more after releasing the pedal), permanently off (if the switch cannot close when you depress the brake pedal) or working intermittently. In each case, the switch creates a dangerous situation for you and other drivers on the road. Fortunately, you can replace it in a matter of minutes and with a minimum of tools.

Instructions

Removing the Brake Light Switch

    1

    Park your vehicle in a safe place, away from traffic, where you can work with the drivers door wide open.

    2

    Look under the dashboard and see if you have plenty of room to access the brake light switch mounted in the top section of the brake pedal arm. If not, remove the under-dash panel using a Phillips head screwdriver. The switch mounts on a metal pin or flange attached to the brake pedal arm.

    3

    Unplug the brake switch electrical connector. Be careful not to break the locking tab on the plastic connector.

    4

    Pull off the pushrod retaining clip using a pair of needle nose pliers.

    5

    Remove the nylon washer from the brake pedal pin or flange by hand. On some vehicle models, you may need to remove a plastic bushing from the pedal pin or flange as well.

    6

    Slide the brake light switch off the pin or flange so the outer hole in the switch mounting bracket clears the pin or flange.

    7

    Pull the switch off the pin or flange. The inner hole on the other side of the switch-mounting bracket is U-shaped, so the brake light switch actually straddles the end of the brake booster pushrod, which is also attached to the brake pedal pin or flange.

Installing the New Brake Light Switch

    8

    Position the new brake light switch on the brake pedal pin or flange, straddling the end of the brake booster pushrod.

    9

    Slide the new brake switch and brake booster pushrod against the brake pedal arm so the pedal pin or flange goes through the new switch outer mounting bracket hole.

    10

    Install the nylon washer on the brake pedal pin or flange and bushing if your particular model is so equipped.

    11

    Install the pushrod retaining clip using the needle nose pliers.

    12

    Plug in the brake switch electrical connector.

    13

    Replace the under-dash panel, if you had to remove it, using the Phillips head screwdriver.

How to Remove the Rotors From a 1994 Honda Accord

Every time the brake system on a 1994 Honda Accord is about to be serviced or removed, it is a good idea to check the thickness of the rotors. A worn rotor that is below the acceptable limits heats faster and is more susceptible to warping and should be replaced. Each rotor has the minimum dimensions embossed on the center hub. Always replace the brake pads as well when replacing the rotors. The used pads are no longer a flat surface and would accelerate wear on the new rotors.

Instructions

    1

    Raise and support the car on jack stands. Remove the wheel/tire assembly using the lug wrench. Place the drip pan under the caliper. Use a wrench to loosen the caliper bleeder valve.

    2

    Insert the screwdriver between the brake pad and the rotor and pry the brake pad in toward the vehicle to compress the piston into the caliper. Once the piston is fully compressed in the caliper, close the bleeder valve and tighten with the wrench.

    3

    Use a 3/8-inch drive ratchet and a socket to loosen and remove the two bolts from the caliper. Use a suitable piece of wire and suspend the brake caliper from the spring so that it does not hang by its hose.

    4

    Remove the two bolts in the caliper-mounting bracket, using the ratchet and a socket. Unscrew the two retaining screws in the rotor using a Phillips screwdriver. Pull the rotor off.

    5

    Slide the new rotor on and replace all parts in reverse order of removal.

How to Replace a Rear Windshield

How to Replace a Rear Windshield

Replacing a rear windshield takes patience and the right equipment. It will also take research to determine how the moldings on the glass are held in place. If they are rubber moldings, which most newer vehicles have, they will have to be cut out when the glass is removed. New moldings will have to be purchased from an auto glass company. Some vehicles use chrome trim, and special trim removal tools will need to be used to prevent molding damage.

Instructions

    1

    Remove the back glass moldings. Using a windshield removal draw knife, cut through the urethane rubber that is holding the glass to the frame. The most common knife is set at a 90-degree angle and has a short, flexible cable attached that is pulled by a handle. A good amount of force is needed to pull the knife through the tough urethane. A long straight-razor knife is also used to quickly work through straight cuts.

    2

    Clean the old urethane out of the glass frame. Windshield urethane is tough. It will take a sharp blade and patience to remove.

    3

    Pump in new urethane with a caulk gun. Windshield urethane comes in metal sleeves and is available at auto parts stores. Clean the new glass and apply a bonding agent to help the glass adhere to the urethane.

    4

    Install the back glass. Install the rubber molding at this time if it is called for. Have an assistant help position the glass, lower the bottom into place on the glass stops, and gently tilt the top into place. Press down on the glass to seat it into the urethane. Install the chrome moldings if the vehicle is so equipped.

How to Remove the Rotors on a Hyundai Accent

All you need is a little mechanical knowledge and some automotive tools to easily remove the rotors from your Hyundai Accent. Auto repair shops and dealerships charge outrageous prices in labor and you can easily invest that money into the tools you'd need in order to perform the repair and have them for future uses.

Instructions

    1

    Open the hood to the Hyundai Accent and remove half of the fluid from the master cylinder reservoir using a turkey baster. Discard the old fluid and replace the master cylinder cover securely. Place a wheel chock behind one rear tire.

    2

    Loosen the lug nuts of both front tires with the breaking bar and a 21 millimeter socket.

    3

    Raise the front end of the car with the floor jack and place the jack stands below the front frame rails to support the car. Remove the lug nuts and wheels.

    4

    Remove the two caliper bolts using the ratchet and a socket. Hang the caliper from the coil spring with the bungee cord then compress the piston of the caliper inward using the C-clamp.

    5

    Remove the brake pads in the caliper anchor, but establish which is the outboard pad and which is the inboard pad and the top and bottom of each pad as it sits in the anchor. You will want to replace the pads in the same manner they were removed if you're not replacing them.

    6

    Remove the two caliper anchor bolts using the ratchet and a socket. These will be very tight and require some strength to remove. Remove the caliper anchor.

    7

    Remove the screw located on the center hub of the rotor using the impact screwdriver (set in reverse), the Phillips head bit and a hammer. Strike the impact screwdriver on the head until the screw loosens.

    8

    Remove the rotor, using the two 8-by-1.25 mm bolts and screw them into the hub holes provided on the face of the rotor. Thread them in and tighten them 3 to 4 times with the ratchet and a socket. Then switch to the next bolt. Keep going back and forth between the two bolts.
    If the threads strip out, strike the rotor with force using the rubber mallet until you shock it from the hub.
    If you're removing the rotor to replace it, use a regular hammer to strike it with and skip the first two options. It'll be easier and much quicker.

    9

    Replace the parts when you're finished by reversing the procedure.

    10

    Torque the lug nuts on the tires after you've lowered the Accent with the torque wrench set to 80 ft.-lbs. and the 21 millimeter socket.

    11

    Pump the brake pedal until it feels normal to restore the hydraulic pressure back to the compressed caliper pistons. After, check and add new DOT 3 brake fluid to the master cylinder reservoir. Don't forget to remove the wheel chock.

How to Replace the Windshield in a 1967 Chevy Nova

How to Replace the Windshield in a 1967 Chevy Nova

If the windshield on your 1967 Chevy Nova is cracked, it is wise to replace it quickly. Even a small crack can grow into a large one over time. A cracked windshield could lead to a ticket, and also presents a safety problem. Your windshield does not just block the wind, it is also one of your car's main safety devices. The correct installation of the windshield is crucial to protect you in case of an accident.

Instructions

    1

    Inspect the broken windshield and frame around it. Check for damage to the mounting area. Dents, cracks and corrosion can make a good seal for the new windshield impossible. If there is damage, get it repaired before installing the new windshield.

    2

    Lay down the drop cloths. Place a vinyl cloth on the hood of the car under the windshield. Spread out another cloth over the dashboard of the car. This is to protect both the exterior and interior of the car from any broken glass from the old windshield.

    3

    Take off the wiper blades and arms. You can use a screwdriver to remove them.

    4

    Pull the windshield gasket off. Insert the flat-head screwdriver under the gasket. Using the screwdriver, pry and pull the gasket off. Do not remove the chrome from the Nova.

    5

    Remove the sealant. Using a razor blade go around the entire windshield to cut free the windshield from the sealant.

    6

    Take out the windshield. Insert the crow bar under the windshield and carefully remove it. Your assistant can help you with it.

    7

    Clean the new windshield and mounting surface. This area must be clean to ensure a tight bond. Run sandpaper around the mounting area. Apply the bonding agent around the area. Sand the new windshield around the edges. Apply the bonding agent to it.

    8

    Lay down a bead of silicone. It should go around the entire mounting area.

    9

    Install the new windshield. Have your assistant help you in carefully placing the windshield. Press firmly and let the bonding agent dry. Replace the gasket around the windshield.

How to Replace the Rear Brake Pads on My Silverado 2500

The Chevy Silverado 2500 is a -ton, mid-duty pickup truck. The 2500 has a larger, more substantial, brake system than the 1500 Silverado. The heavy-duty, four-wheel disc brake system is necessary to stop the truck with heavy loads in the bed. The brake pads are larger than those on the 1500 but wear at roughly the same rate. While there is no set interval for brake pad replacement, you should inspect them every time you rotate the tires and replace the back brakes when the pads fall below 3 mm in thickness.

Instructions

    1

    Shove wheel chocks against the front and back of the Silverado 2500's left front tire. Turn all the rear lug nuts counterclockwise to loosen them with a lug wrench.

    2

    Lift the rear end of the Silverado 2500 with a floor jack. Support the rear end on jack stands placed under the rear axle.

    3

    Pull the rear lug nuts and back tires off the Silverado 2500 to access the back brakes.

    4

    Place a drip pan under the left rear brake rotor. Wash all the brake dust off the caliper and rotor with brake cleaner.

    5

    Unbolt the left rear caliper with a socket set. Remove the caliper from the mount by hand. Extricate the old brake pads and discard them.

    6

    Wash the inside of the caliper with brake cleaner, paying special attention to the pistons and slide pins. Lubricate the caliper slides with white lithium grease to prevent seizing.

    7

    Force the caliper pistons back into the caliper with a caliper tool. Remove the tool and immediately insert the new brake pads.

    8

    Set the caliper back into the mount and bolt it in with the socket set.

    9

    Move to the Silverado 2500's right rear and repeat Steps 4 through 8. Remount the back tires and lug nuts. Lower the truck off the jack stands with the jack.

    10

    Re-torque the lug nuts to 140 ft.-lbs. with a torque wrench.

How to Change a Driver Side Window on a 2000 Mustang

If your driver-side window becomes damaged, it can put your vehicle at risk from further damage or theft. Changing the driver-side window on your 2000 Mustang is essentially the same as in every other car, and it can be completed in a matter of minutes. You can pick up the tools needed for the job from your local auto parts store.

Instructions

    1

    Open up the driver's door. Use a Phillips screwdriver to remove the screws attached to the door panel. Lift the door panel away from the door.

    2

    Remove the screws that are attached to the door handle. Pull the door handle away from the door. Reach in the hole left by the removed door handle and unhook the linkage arm. This will allow you to remove the entire door handle assembly.

    3

    Lower the regulator to its lowest point within the door frame. Use a hex wrench to remove the hex bolts attached to the window pane.

    4

    Pull the window pane out of the driver's side door. Take care not to damage your hand or the door frame.

    5

    Place a new window pane into the door frame. Fix the window to the regulator with the hex bolts. Reattach the door assembly by following the removal steps in reverse.

How to Change Rotors on a Ford F150

How to Change Rotors on a Ford F150

A Ford F-150 pickup truck uses front disk brakes, which incorporate a rotor and caliper for stopping the vehicle. As pressure is applied to the hydraulic system, the caliper squeezes two pads against the rotating friction surface of the rotor. These pads and the rotor itself can wear out and require replacement, which can take the average backyard mechanic about a half hour to complete.

Instructions

    1

    Raise the truck at the front wheel with the floor jack, placing the head onto a frame rail, not the body or suspension. Pump the lever of the jack until the wheel is in the air. Support the jack at the area with a jack stand.

    2

    Remove the wheel by turning the lug nuts counterclockwise, then pulling the wheel from the hub. Store the wheel away from the work area. Inspect the brake assembly for obvious signs of damage, leaking or debris.

    3

    Remove the caliper by turning the twin rear mount bolts in a counterclockwise direction. Unplug the ABS sensor from the wiring harness by pulling the adapter plug from the socket on the caliper. Slide the caliper from the rotor and secure it with zip ties onto the control arm. Do not let the caliper dangle by the brake lines. The brake pads can be gently pried out with a screwdriver and replaced.

    4

    On many two-wheel drive models, the rotor will pull free from the hub without much effort. On four-wheel drive models, a spindle nut in the center of the rotor keeps it in place. Turn the spindle nut counterclockwise to remove it, then slide the rotor off. Late models could have internal wheel bearings, making replacement expensive.

    5

    Replace the rotor and secure the spindle nut in clockwise direction, if applicable. Slide the caliper back into position and secure the rear mount bolts clockwise. Plug the ABS sensor into the caliper's socket, if applicable.

    6

    Replace the wheel by turning the lug nuts clockwise, in an alternating direction. Remove the jack stand and lower the truck. Repeat the entire procedure on the opposite brake.

How to Choose Auto Glass

How to Choose Auto Glass

You're driving down the highway and a rock bounces up and chips your windshield. This happens to almost everyone. Unless the damage is sealed quickly, the crack will grow and you'll need a new windshield. Windshields, as well as door and back windows of vehicles, provide safety and good visibility for drivers. Spend time researching and choosing the best quality replacement glass for your vehicle. Know that your efforts can save you money and protect your vehicle and you.

Instructions

    1

    Research the different glass types. The original manufacturer of your car window when it was new produces dealer glass, the most expensive type of glass. Original equipment manufactured (OEM) distribution glass provides the exact specifications as dealer glass, at less expense. Different manufacturers produce this glass besides the original dealer. Research who top OEM distributors.

    2

    Avoid using another main type of auto glass, aftermarket glass. This type of glass typically costs less, but is usually not made to the exact specifications as OEM or dealer glass. Problems with aftermarket glass in autos may include improper fit, leakage and wind noise.

    3

    Contact an authorized auto glass technician and inquire what types of OEM glass they can provide for your vehicle.

    4

    Require that the auto glass technician you have chosen uses OEM parts and adhesives along with the glass during installation. These are proven parts and adhesives designed to work with OEM auto glass.

How to Remove an RV Window

Recreational vehicle windows are typically flat panes of glass held to a window frame with small screws, plastic glass supports and tight rubber gaskets. During the lifespan of the RV, it may become necessary to remove the pane of glass for replacement, cleaning or repair. The average RV owner can remove the window from a motor home in about 20 minutes.

Instructions

    1

    Peel the rubber window gasket from the outer edge of the glass pane. The gasket will have a split in its continuity that can be worked loose with a screwdriver, then pulled free by tugging on it. As the gasket comes loose, the outer mount screws will become visible.

    2

    Remove the inner rubber gasket, if applicable, by pulling it free from the window mount in the same fashion as the outer gasket.

    3

    Remove the mounting screws on the inside of the window mount by turning them counterclockwise. The plastic window frame will become loose as the screws are removed. Some units will free the pane of glass when either side (inner or outer) is unscrewed, most models will release the glass only when both sides are unscrewed.

    4

    Remove the outer mounting screws by turning them counterclockwise. As the frame becomes free, the pane of glass could shift its position. Carefully work the plastic frame mount from the glass without allowing the glass to fall out of the vehicle.

    5

    Pull the glass toward the outside of the RV and carefully lower it to the ground. Two-piece sliding windows will still come out as one part, with two panes held in place with a secondary frame.

How to Fix a Stuck Parking Brake in a Tacoma

The Toyota Tacoma has been hugely popular for Toyota, but the truck isn't without problems. One of them is corrosion and rust issues. If your truck has a stuck parking brake, chances are it's due to rust on the brake cables. Fixing it takes a bit of effort, but it can be done in a garage with a few tools.

Instructions

    1

    Lift up the rear of the vehicle using the jack and support the axle on the jack stands. Be sure the vehicle is secure before you crawl underneath it.

    2

    Locate the parking brake cable on the drums. There is one long cable that goes from the front of the truck that then splits off at the axle into two different sections. It's a flexible, metal line that goes into the back of the brake drums.

    3

    Pull on the emergency brake line to see if it breaks free. If it does, then the job is done. If not, move on to the next step.

    4

    Spray the penetrating oil into the hole where the emergency brake line goes into the drums. This is going to lubricate the line and should free up the corrosion.

    5

    Pull on the line again, trying to break it free. If it doesn't, repeat with the penetrating oil. The line will eventually break free and be good to go. To stop this from happening again, use the emergency brake frequently to slow down corrosion.

How to Fix an Auto Windshield

Cracks and chips in windshields are, unfortunately, a common occurrence. Small cracks and chips are hazardous if they are left unattended. A small crack will eventually spread, making it necessary to replace the windshield. A crack on certain spots of the windshield may easily distract a driver or interfere with his view. Repairing a crack in the windshield will take about 30 minutes and cost between $10 to $15 for a windshield kit.

Instructions

    1

    Purchase a windshield repair kit at an auto parts store. The repair kit will have a suction device and a resin or glue product to repair the crack.

    2

    Thoroughly clean the crack with a can of compressed air. Do the inside of the windshield as well as the outside. The goal is to remove all the tiny bits of loose glass. Remove the stubborn bits of loose glass with a razor blade.

    3

    Clean the surface area around the crack with a window cleaner. This helps the suction device to adhere better to the window.

    4

    Place the suction device over the crack. The center of the device should be directly over the crack.

    5

    Insert the repair tube into the suction device. Screw it tightly in place. Look at the tube from the inside of the windshield and make sure the tip of the tube is perfectly aligned with crack.

    6

    Open the tube and fill the crack with two to four drops of glue. Remove the repair tube from the suction device.

    7

    Insert the plunger into the suction device and tighten it all the way down. Loosen it for a minute to release air bubbles and then tighten it again.

    8

    Remove the suction device. Place a piece of clear finishing film over the repaired crack. Press the edges of the glue toward the edges. This helps to thin out the glue. Tape the film to prevent it from blowing off. Remove the film after 15 minutes. Allow the repair job to cure for 24 hours before driving the car.

How to Tell if I Need New Brake Calipers

How to Tell if I Need New Brake Calipers

Calipers are very important components in disc braking systems. Pistons expand from hydraulic pressure on demand when the brake pedal in the vehicle is applied. The pistons squeeze the brake pads, which then contact the surface of the rotor and slow the vehicle down. When a caliper becomes defective, there will be some obvious telltale side effects. Identifying the symptoms will help you find the bad component and then replace it.

Instructions

    1

    Open the hood and check the fluid level of the master cylinder. A leaking piston, bleeder or brake hose will drain the reserve fluid from the master cylinder eventually. If necessary, top the master cylinder off with clean brake fluid.

    2

    Test drive the vehicle to begin diagnosing the calipers. Choose a parking lot or low-traffic road if possible. Before taking off, be sure you have a firm brake pedal. If the brake pedal fades to the floor with a poor braking response, do not test drive the vehicle.

    3

    Bring the vehicle up to 30 mph and then apply the brakes firmly. Determine whether the vehicle pulls to the right or the left when the brakes are applied. This would be a good indication that a caliper piston is sticking and only one side of the brakes are working properly.

    4

    Drive the vehicle for 10 to 15 minutes applying the brakes often. Bring the vehicle back to the area where you plan on disassembling it for further diagnosis. Before beginning, place you bare hand near each wheel that employs calipers. Do not touch the wheel because a stuck piston will heat the brakes and nearby components up severely and you could burn your hand. Burning brakes will give off both intense heat and a pungent burning odor. If a wheel is indeed extremely hot, allow it to cool down before proceeding.

    5

    Lift the axle of the vehicle that contains the suspect caliper. Use the jack to lift it and be sure to place it safely onto jack stands.

    6

    Remove the wheel using a lug wrench to remove the wheel nuts.

    7

    Remove the two caliper guide bolts using a ratchet and a suitable socket.

    8

    Pry the caliper off of the rotor with a small pry bar. Some calipers will contain pads attached to the caliper while others will leave the pads behind in the caliper anchor.

    9

    Inspect the caliper for any visible signs of fluid leaks. Leaking brake fluid will be very obvious. Thoroughly inspect the piston area, the bleeder screw and the brake hose connection. Also inspect the rubber protective boot surrounding the pistons. Tears or rips in the boot will not necessarily mean the caliper is defective, but it will compromise the pistons eventually. While you're at it, inspect the brake hose for any visible signs of cracking or rips in the rubber.

    10

    Hang the caliper to the suspension using a caliper hook or a wire hanger. Compress the piston using a C-clamp or a caliper piston reset tool. Some rear disc-brake calipers will require the reset tool to screw the piston into the bore while most all front calipers will require compressing the piston into the bore with a C-clamp. Compress it slowly. If the piston does not bottom out in the bore or resists compression, the piston is bad and the caliper needs to be rebuilt or replaced.
