How to Change the Brake Pad Sensor on a 2001 Mercedes E320

How to Change the Brake Pad Sensor on a 2001 Mercedes E320

The 2001 Mercedes E320 is equipped with a sensor on the brake pads that controls a warning light on the dash that tells the driver when it is time to change them. The sensor is supplied with a 12-volt signal at all times, and when the plastic outer covering is worn away by contact with the rotor the inner copper contact provides a path to ground for the voltage when it touches the rotor. Replace sensor when the brake pads are replaced; many aftermarket pad sets come with a new sensor installed.

Instructions

    1

    Place wheel chocks behind the rear wheels of the Mercedes and set the parking brake. With a floor jack, lift the front of the car, using the factory lift points located just behind the front wheel openings. Place jack stands under the front sub-frame to support the weight of the car and lower it onto the stands. Remove the front wheels using a lug wrench.

    2

    Locate the sensor. Each pair of brake pads on the Mecedes is equipped with one sensor in the pad. Unplug the wiring harness connector located near the front suspension. Unsnap the old sensor from the pad with needle-nose pliers--squeeze the small metal latches together while you pull the sensor from the pad.

    3

    Install the new sensor by pushing it into the pad until the latches snap into place. Hold the sensor in the opening on the pad backing plate as you route the wiring for the new sensor in the same manner the original was routed. Plug the new connector into the wiring harness.

    4

    Reinstall the front wheels and torque the lug bolts to 73 foot-pounds using a torque wrench. Raise the car off the jack stands and remove the stands. Lower the Mercedes to the ground and test drive the car to verify that the warning light is off.

How to Remove Sprayed-On Window Tint

How to Remove Sprayed-On Window Tint

Traditional window tint is applied as a film, which is custom fitted to the vehicle. On some cars, though, people use sprayed-on window tint, which works but doesn't always give a consistent appearance. As a result, some people don't want the sprayed-on tint on their vehicle and decide to take it off. The process of removing the sprayed-on tint is basic enough, but it does involve some elbow grease and a lot of patience. It should take approximately 30 minutes per window to accomplish.

Instructions

    1

    Open the door and sit inside the vehicle. Roll down the window just slightly so that there is about 1 inch of difference between the top of the glass and the window jamb. Spray down the window using the glass cleaner so that it is very wet.

    2

    Hold the razor blade at a sharp angle to the glass so that the blade is almost parallel to the window itself. Scrape the glass using the razor blade, occasionally wiping off the blade using a paper towel. Scrape the entire window until all of the visible glass is clear of the tint. Roll up the window and scrape any remaining tint off of the window.

    3

    Wet down the glass with the glass cleaner. Wipe the glass clean using a microfiber towel. Look at the glass again to make sure that there is no remaining tint on the glass. If you find some, scrape it off with the razor blade and clean the glass again.

How to Repair a Pinhead Chip in My Windshield

Windshield repair can be a complicated procedure, requiring an optically compatible bonding resin to fill and stabilize a large damaged area. Pinhead chip repair is altogether different. With a chip the size of a pinhead, there is no subsurface cracking, spider-webbing or severe damage to deal with. By following a few steps your repair will bring satisfactory results.

Instructions

    1

    Clean the pinhead chip and surrounding area with alcohol. Examine the chip closely and make sure there is only a small, surface chip. If the vehicle is in a sunny spot, move it to a shaded area. Let the glass cool.

    2

    Tape a piece of paper towel below the area to be repaired. This creates a dam to capture any runoff of glue that could harm the vehicle paint.

    3

    Apply a drop or two of glue to fill the pinhead chip. Windshield rearview-mirror glue has a bonding agent in the package that must be applied first. Super Glue-type adhesives are applied directly to the area. Allow either product to set for several minutes before going on to the next step.

    4

    Level the glue with a razor blade, carefully pulling it over the filled area. This will flatten the repair and make it more optically pleasing. Clean the entire glass, and finish the repair by coating the windshield with Rain X or an equivalent product that will fill surface abrasions.

1987 Toyota Pickup: How to Change Out the Master Brake Cylinder

Though the Tacoma and the Tundra get all of the fame, the first Toyota pickup sold in the U.S. was the Stout in 1964. The Stout was short-lived, as Toyota discontinued it in 1967 and replaced it with the Hi-Lux in 1969. With no explanation, Toyota kept the Hi-Lux body, but eliminated the Hi-Lux name in the U.S. in favor of the uncreative Pickup name Hi-Lux remained throughout the rest of the world. The 1987 Toyota Pickup came standard with power hydraulic brakes, which used a master cylinder to create pressure in the brake lines. When replacing the master cylinder, you must bench-bleed it before installation.

Instructions

Changing the Master Cylinder

    1

    Pull the cap off the master cylinder reservoir. Siphon all of the fluid from the reservoir with a clean turkey baster. Transfer this fluid to a small, sealable container.

    2

    Position a small drain pan under the master cylinder and loosen the steel brake line running into the master cylinder with a line wrench. Allow the fluid to drain from the lines into the drain pan, then remove the lines from the master cylinder. Wrap the end of each line with a clean, lint-free cloth to prevent debris from getting into the hydraulic system.

    3

    Press and hold the unlocking button on the wiring harness plugging into the master cylinders brake fluid level sensor wiring, if so equipped, and unplug the harness.

    4

    Remove the four master cylinder-retaining nuts with a ratchet and socket. Pull the master cylinder from the brake booster.

    5

    Set the new master cylinder in a bench vise with rubber jaw protectors installed. Tighten the bench vise until it holds the master cylinder in place. Hand-thread bleeder hoses into the brake line ports on the master cylinder, then snug them with a line wrench.

    6

    Route the bleeder lines into the master cylinder reservoir and fill the reservoir to the Max line with new DOT 3 brake fluid position the bleeder hoses so the ends are in the reservoir to submerge them in the brake fluid.

    7

    Press and release the plunger on the rear of the master cylinder with a wooden dowel rod and watch the ends of the bleeder hoses in the brake fluid for bubbles. Repeat this step until no bubbles come from the hoses.

    8

    Unscrew the bleeder hoses with a line wrench and remove them from the master cylinder. Press the cap onto the master cylinder.

    9

    Set the new boot included with the new master cylinder onto the raised section on the rear of the new master cylinder with the Up marking facing up. Set the master cylinder on the brake booster, guiding the mounting studs on the booster through the mounting holes in the master cylinder. Hand-thread the nuts onto the mounting studs.

    10

    Hand-tighten the brake lines into the ports on the master cylinder.

    11

    Torque the master cylinder-retaining nuts to 9 foot-pounds with a torque wrench and socket. Tighten the brake lines to 11 foot-pounds with a torque wrench and crows foot attachment.

    12

    Plug the brake fluid level wiring harness back into the Toyotas wiring harness.

Bleeding the Brake System

    13

    Raise the front of the truck with a floor jack and slide jack stands under the trucks frame rails. Lower the truck onto the jack stands. Raise the rear of the truck with a floor jack and place jack stands under the rear axle.

    14

    Crawl under the right rear wheel and find the brake bleeder valve the 1/4-inch metal valve on the top of the drum backing plate. Press a 1/4-inch diameter rubber hose onto the bleeder valve and set the other end in a clean, clear container. Fill the container with fresh DOT 3 brake fluid until fluid submerges the end of the hose.

    15

    Instruct an assistant to press and release the brake pedal slowly until the pedal feels firm. Tell your assistant to hold firm downward pressure on the pedal. Turn the bleeder valve a quarter-turn counterclockwise with a combination wrench to open it. Look at the end of the hose in the brake fluid and look for air bubbles. Repeat this step until no bubbles appear.

    16

    Remove the rubber hose from the bleeder valve. Refill the master cylinder to the Max line with fresh DOT 3 brake fluid.

    17

    Repeat steps 2 through 4 to bleed the remaining three wheels, in the following order: left rear, right front and left front. On the front wheels, the bleeder valve is on the rear of the brake caliper, as they are disc brakes.

    18

    Raise the rear of the truck off the jack stands with a floor jack and remove the jack stands. Lower the rear of the truck to the ground. Raise the front of the truck off the jack stands with a floor jack and remove the jack stands. Lower the front of the Toyota to the ground.

    19

    Take any old brake fluid to an automotive fluid recycling center for disposal. Some auto parts stores take old fluid for free.

How to Replace the Rotors on a Ford Excursion

How to Replace the Rotors on a Ford Excursion

The Ford Excursion was manufactured between the years of 2000 and 2005 by the Ford Motor Company. The large SUV featured front disc brakes on both two-wheel drive and four-wheel drive models. Some Excursions in the two-wheel and four-wheel drive categories also featured rear disc brakes. The main component of disc brakes is the rotor, also referred to as the disc. The hydraulic pistons of the calipers extend outward on braking demand, squeezing the brake pad friction material against the surface of the rotor, thus slowing and stopping the vehicle.

Instructions

    1

    Park the Excursion on a level surface suitable for lifting and supporting the heavy SUV. Apply the parking brake only if you're replacing the front brake rotors. Turn off the air suspension button located in the rear of the vehicle.

    2

    Place a wheel block or block of wood behind one of the rear tires for added safety when replacing the front brake rotors. Place the block in front of one of the front tires if you're replacing the rear brake rotors.

    3

    Crack the lug nuts loose with a breaker bar and suitable socket on the wheels where you're replacing the rotors.

    4

    Lift the Excursion with the weight-rated floor jack and support the axle onto weight-rated jack stands. Remove the lug nuts and wheels.

    5

    Place a the C-clamp over the caliper so the top of the clamp is touching the inner caliper housing and the screwing bore of the clamp is against the bottom of the outer brake pad plate. Tighten the clamp just enough to allow room for the new rotor (a turn or two). Do not bottom the caliper pistons into their bores.

    6

    Remove the upper and lower caliper plate bolts located on the back side of the knuckle with the breaker bar and a socket. Remove the caliper and plate assembly and then support it on the suspension with heavy-duty caliper wire.

    7

    Remove the brake rotor from the hub. If the brake rotor does not come off the hub due to rust and other corrosives, spray the penetrating lubricant around the center hub hole of the rotor and allow a few minutes for the spray to soak in. Use a hammer to strike the inner plate of the rotor outward and turn the rotor 1/4 turn between strikes until the rotor breaks free from the hub. On rear rotors, strike the front hub of the rotor (being careful not to hit the lug studs) and turn 1/4 turn between strikes until the rotor breaks free from the hub.

    8

    Spray the replacement rotor with brake/parts cleaner spray to remove the sticky rust preventative solution coating. Spray both sides thoroughly.

    9

    Place the replacement rotor onto the hub and reverse the remaining procedure to reassemble the brakes and wheel.

    10

    Tighten the caliper plate bolts to 148-foot pounds with the adjustable torque tool and a socket.

    11

    Replace the wheels and lug nuts and snug the lugs nuts tightly to seat the wheels to the hub.

    12

    Lower the Excursion and re-tighten the lug nuts with the adjustable torque tool set at 110 foot-pounds. Move from one lug nut to the opposite lug in a star or crisscross pattern.

    13

    Apply the brake pedal several times until it feels firm. Remove the wheel block, release the parking brake and turn the air suspension back on before test driving the Excursion.

Fiero Windshield Replacement Instructions

Fiero Windshield Replacement Instructions

Because the Fiero sits low to the ground, it is prone to chips from rocks being flung from the tires of SUVs and trucks. Small chips and cracks may not look dangerous, but they can quickly spread and compromise the integrity of your windshield. If you don't repair or replace your Fiero's windshield, it may eventually shatter.

Instructions

    1

    Clean off any residual urethane on the windshield frame using a wet rag.

    2

    Clean off the pinch weld area on the windshield frame with a cleaning brush, removing all debris.

    3

    Paint urethane primer onto the black edging of the replacement windshield.

    4

    Run a thick bead of urethane around the entire edge of the windshield frame.

    5

    Press the replacement windshield onto the windshield frame from outside the Fiero. Allow the urethane to cure for 25 hours before driving.

How to Install Rear Disc Brakes on a 2000 Ford Mustang

Installing new rear disc brakes on a 2000 Ford Mustang is a common repair project for the Mustang enthusiast. The rear brake system used in the 2000 Mustang is a single piston disc brake with an actuator built into the caliper for parking brake function. This is the same system used on Mustangs from 1994 to 2005. The installation process is a straightforward "remove and replace" procedure and can be completed in about an hour by the average Mustang enthusiast.

Instructions

    1

    Loosen the rear lug nuts half a turn with a lug wrench. Wedge wheel chocks in front of and behind the front wheels. Raise the rear of the Mustang using a floor jack placed under the rear differential and slide jack stands under the rear axle tubes. Remove the rear wheels.

    2

    Remove the caliper bolts that attach the caliper to the caliper mounting bracket using a 13-mm wrench. Remove the caliper mounting bracket bolts from the rear axle flange using a 15-mm socket and ratchet and lift the bracket over the brake rotor. Slip the rotor off the rear hub. A few sharp blows from a hammer around the rotor near the hub will loosen the rotor if it is rusted on.

    3

    Compress the Mustang's caliper piston into the caliper housing using the caliper piston tool. Slip the tool between the caliper housing and the piston and turn the disc on the end of the tools center shaft until it engages the slots in the piston. Hold the disk against the piston and turn the tools outer nut by hand until the tool expands against the caliper housing.

    4

    Turn the outer nut counter clockwise using a one-inch wrench, while simultaneously turning the center shaft clockwise with a 14-mm wrench, until the piston is retracted into the housing.

    5

    Scrub the hub clean using a wire brush to remove rust and scale. Slip the new rotor onto the hub and secure it to the hub using a lug nut screwed onto one of the wheel studs. Apply a drop of thread locking compound to the bracket bolts. Place the caliper bracket over the rotor and reinstall the bracket bolts. Torque the caliper bracket bolts to 64 to 88 ft-lbs using a torque wrench.

    6

    Slip the new brake pads into place on the bracket. Place the caliper over the pads and onto the caliper bracket. Reinstall the caliper bolts. Reinstall the wheels and lower the car to the ground after removing the jack stands. Torque the wheel to 100 ft-lbs using the torque wrench. Apply the parking brake and press the brake pedal several times before test driving the Mustang.

How to Smooth Windshield With Resin

Smooth out a newly repaired windshield with resin. Once the anaerobic resin has been cured over the break of a windshield, you need to use pit resin to smooth out the glass and make the windshield look as good as new.

Instructions

    1

    Gather your tools. Have cellophane patches and a couple of resins, an anaerobic resin and a pit resin like Stone Chip or Chipfix, Inc. that work with ultraviolet light. You also need a UV light. Pull out a regular razor blade to scrape the glass and most importantly for windshield repair will be the bridge.

    2

    Understand the process of repairing a windshield of make of. Windshields have two layers of laminated glass. When a rock or something hits the windshield, air gets in between the two layers, which will make the break contract until you have a long crack across the windshield. When the resin is injected inside the break, the bridge fills up the cracks while at the same time it pulls out any air that has been caught between the glass layers.

    3

    Remove the Bridge from the windshield. Once you have drilled out the break and used the Bridge to inject the resin in and siphon the air out between the layers of glass and let that cure under a UV light, it's time to take the Bridge off. Unscrew the feet holding the Bridge to the glass so that the glass doesn't burst. Take off the Bridge.

    4

    Spread a little pit resin on a cellophane patch. The pit resin is the resin that resurfaces the top layer of glass. Place it over the top of where the break was. Watch and make sure it beads up and spreads out across the patch so there aren't any bubbles in it.

    5

    Let the pit resin cure for approximately five minutes under the ultraviolet light or out in the sun. Use the razor blade and scrape down any extra resin until it is nice and smooth. Now simply wipe the glass and polish it up.

How to Remove a '99 Grand Am Window

When the window gets broken in a '99 Grand Am, it can be quite expensive to take to the dealer or other car repair shop to fix. However, it is actually a simple matter to remove the old glass from the window to get it ready for the new glass. This project should take around 40 minutes to an hour to complete, and requires tools that are commonly found around the house.

Instructions

    1

    Remove the door panel cover from your '99 Grand Am. Near the door release handle is a covered screw. Uncover the screw and unscrew the screw. Pull the cover away from the door handle. Use a screwdriver to pop out the locking mechanism with a flat head screw driver. Pull out slowly and set aside.

    2

    Unscrew the screw from under the Grand Am's door loop. Carefully pull the bottom corner of the panel away from the car with your fingers. Unclip all door connectors. If some break, they are fairly cheap to replace. Pull on the panel until the panel is a few inches away from the door, but not completely detached. Unclip all electrical connectors. Pull the panel completely away from the door.

    3

    Peel aside the plastic sheeting that covers the inside of the door. Set aside. Locate all of the door/window clips that hold the window into place. There should be about 8 to 9 clips. Unclip the glass from the clips. Locate the clip attached to the level that controls the level of the window. Loosen it so the new window can fit.

    4

    Remove any glass pieces or glass shards from the previous window. Use your fingers or a vacuum with a tube attachment. Wear gloves when handling any glass. For shattered windows, you will probably need to use both. If the glass you are removing is a whole sheet, you can ignore this step.

    5

    Remove the weather stripping rubber piece from the top of the window frame. You will probably need to use a scraper or a flat head screwdriver for this step. Be patient, this will take a little time. Try and keep the strip together, as you can use it again for the new window.

    6

    Slide the new window down into the gap where it should go. If there are any bolts in the way, unscrew them so that the window can slide in. Take the glass back out and set aside. Wipe the door down with a wet cloth. You can now install the new window.

How to Change the Brake Pads on a 1992 Dodge Dakota

How to Change the Brake Pads on a 1992 Dodge Dakota

The 1992 Dodge Dakota features front disc brake pads and rear drum brakes. The front brakes work three times harder than the rear brakes, so they will need to be replaced more often. While the brake rotors should always be inspected for scoring, grooves or rust pits, it is sometimes possible to just replace the pads (as long as the vehicle is not experiencing a vibration or pulsation when the brakes are applied.)

Instructions

    1

    Apply the parking brake to the Dakota after parking it on a flat, hard surface. Release the hood latch and then place a wheel block behind one of the rear tires.

    2

    Open the hood and remove half of the brake fluid from the master cylinder in the engine compartment with a brake fluid baster. Discard the fluid. Replace the cover to the master cylinder.

    3

    Loosen the front lug nuts a quarter-turn with the lug side of the jack wrench.

    4

    Jack a front wheel high enough to place a jack stand under the frame rail or lower control arm. Lower the jack so the truck is supported by the jack stand and then repeat the step for the other side.

    5

    Remove the loosened lug nuts and wheels.

    6

    Remove the outboard pad spring clip from the caliper by prying it off with a small pry tool. Be careful not to bend it in case the replacement pad set does not include a new one.

    7

    Place the 6-inch C-clamp over the caliper so the top of the clamp contacts the inboard housing of the caliper and the drive of the clamp contacts the backing plate of the outboard pad. Tighten the C-clamp to compress the piston until it is fully seated inside the caliper housing bore. Remove the clamp.

    8

    Remove the upper and lower caliper bolt slide using a 3/8-inch hex-head socket and a ratchet.

    9

    Remove the caliper and pad assembly from the rotor and support the caliper to the front chassis with a length of mechanics wire so it does not dangle from the rubber brake hose.

    10

    Pry the outboard pad off of the caliper housing using a the small bar and then pull the spring clips of the inboard pad out of the caliper piston. Install the new pads onto the caliper in the opposite fashion (inboard first and then outboard).

    11

    Clean the caliper and knuckle mating surfaces (upper and lower) with a stiff wire brush and apply a light coat of anti-seize compound to the mating surfaces.

    12

    Place the caliper and assembly over the rotor and then clean off the caliper sliding bolts with a shop rag. Apply a light coat of anti-seize compound to the slides (not the threaded section at the ends of the bolts). Align them into the caliper and tighten them to 25-foot pounds with the torque wrench and 3/8-inch hex-head socket.

    13

    Perform the replacement procedure for the other side and then replace the wheels and tighten the lug nuts snugly to the hub of the truck.

    14

    Raise the Dakota back up with the lifting jack high enough to extract one jack stand at a time and place the truck back on the ground.

    15

    Torque the front lug nuts with the torque wrench and socket to 100-foot pounds in a star pattern.

    16

    Pump the brake pedal until it feels firm, recheck the master cylinder brake fluid level and then add new brake fluid to top off the reservoir if necessary.

    17

    Remove the wheel block, release the parking brake and then test drive the Dakota.

How to Replace the Windshield on a Ford Taurus

Rock or stone chips are the most common causes of damage to a windshield. The Ford Taurus can be prone to this type of damage due to its ride height. This is especially true of older models of the Taurus, which were smaller than the current design and sat lower to the ground. Although replacing the windshield is a complex task, the design of the Taurus's front windshield makes it a pretty straightforward task.

Instructions

    1

    Pry up on the the plastic trim molding with a windshield trim removal tool. Wedge the teeth of the tool under the trim and pry up on it.

    2

    Cut the urethane molding around the outside of the glass with an automotive cutting knife.

    3

    Pull the windshield off.

    4

    Clean the Taurus frame where the new windshield will go. Make sure to remove the old urethane residue and trim the molding back to 3mm with a razor.

    5

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

    6

    Apply a liberal amount of urethane primer to the frit band on the windshield. The frit band is the black strip running around the outside of the glass on the windshield.

    7

    Apply a bead of urethane to the recess on the frame where the windshield will be mounted.

    8

    Align the windshield on the frame and press the windshield into place. Allow the urethane to cure for 12 hours.

How to Change Disc Brakes on a 1965 Ford Falcon

How to Change Disc Brakes on a 1965 Ford Falcon

The Falcon is one of Ford's great classics. According to Dearbornclassics.com, the original 1964 Mustang was composed mostly of design elements and chassis pieces of the Falcon. The 1965 Falcon was available as a two or four door hardtop. It had disc brakes on both the front and the rear, which made changing them rather simple right at home. With a jack and a tire iron handy, changing all four brakes takes about two hours.

Instructions

    1

    Loosen all of the lug nuts with the tire iron two full rotations counterclockwise.

    2

    Place the jack underneath the axle and jack up the car until the tires have 2 inches of clearance from the ground. Set the jack stands underneath the axle. Remove the tire.

    3

    Remove the bolts from the caliper mounting bracket with the socket wrench. Tie the bracket to the car to prevent strain on the brake line. The brake line is the black hose protruding from the rear of the bracket.

    4

    Remove the brake pads from the bracket. The brake pads simply slip out of the bracket.

    5

    Compress the caliper. The caliper is the cylinder in the center of the bracket, and you can compress it by pressing it down by hand.

    6

    Install the new brake pads. They will slide into the same spot where the old ones were.

    7

    Rebolt the caliper mounting bracket to the rotor with the socket wrench. Put the tire back onto the rotor and lower the vehicle. Tighten the lug nuts with the tire iron.

How to Remove an E30 Sunroof

The BMW E30 body style was produced from 1982 to 1990, and included all of the 3-series cars. Some of these cars came with a sunroof, which allowed the sun to shine into the interior when open. These sunroofs have many moving parts, and over time, they can degrade and wear down. If that happens, the sunroof may get stuck or may not open at all. To fix the issue, the sunroof needs to be removed from the car so it can be replaced or serviced.

Instructions

    1

    Sit in the driver's seat. Slide back the inner sunroof lid approximately 4 inches. Pull off the pinch molding that surrounds the perimeter of the sunroof with your hands. Close the sunroof lid.

    2

    Unscrew the screws on the perimeter of the gates using the Phillips-head screwdriver. Remove the retainers on the sides of the lid, unscrew the center screws on the lid, and then take it off of the BMW.

    3

    Pull off the motor around the sunroof motor with your hands. Unplug the wiring harness to the sunroof motor and then remove it from the assembly using the Phillips-head screwdriver.

    4

    Slide back the sunroof cables using your hands. Pull off the rail covers on the sunroof rails, then slide the sunroof cables out of the tracks.

    5

    Put the cable back into the center position on the gate and the push off the sunroof.

How Does a Pendulum in a Brake Controller Work?

How Does a Pendulum in a Brake Controller Work?

    When a vehicle towing a trailer is forced to slow down or stop, the trailer must also stop or else slam into the back of the towing vehicle. The trailer, which is dependent on the towing vehicle for power, may have difficulty stopping effectively when the towing vehicle brakes, due to the forward momentum of the trailer. For this reason, brake controllers are installed. Brake controllers manage the speed of the trailer in relation to the towing vehicle. There are various types of brake controllers available for towing vehicles, including proportional brake controllers.

    Proportional brake controllers, also known as pendulum brake controllers, use a pendulum to detect changes in the tow vehicle's speed. The brake controller can then use this information to adjust the trailer's speed, and match it to the towing vehicle's speed. Since the trailer's speed changes in proportion to the towing vehicle's speed, these are called proportional brake controllers.

    After being installed, the pendulum in a proportional brake controller must be calibrated before being used. This allows the pendulum, which is a motion-sensing device, to synchronize with the motion of the towing vehicle. In this process, the pendulum is adjusted while in place on a flat surface, to ensure that it is pointing straight downward. It should also be tested to ensure that it moves freely with the motion of the vehicle.

    When on a perfectly level surface, the pendulum in a brake controller is pointing down. As the towing vehicle moves forward, the pendulum swings toward the back of the vehicle. As soon as the momentum of the vehicle stops due to a braking action, the pendulum swings forward. The arc of the pendulum's swing is measured, and used to calculate the amount of braking necessary for the trailer. Due to the pendulum's action, it works best when used in areas without large hills.

How to Repair a Power Window on a Dodge Dakota

The power windows on the Dodge Dakota involve multiple components, much like other vehicles. This includes the glass, the window regulator, the run channel and the wiring connecting the regulator to the switches. You may need to replace any one of these to repair the window on your Dakota. Not all models of the Dakota have power windows, and the process to repair one can vary depending on the vehicle's model year.

How to Repair a BMW Rear Window Defroster

How to Repair a BMW Rear Window Defroster

If the grid in your BMW's rear window defroster breaks, and the connection fails, the defroster line containing the break will not work. The typical cost to replace the rear windshield in a BMW was more than $400 as of October 2010. You can do the job yourself for around $10.

Instructions

    1

    Use the voltmeter to find the break in the connection. Turn the defroster on and place the voltmeter probes on either side of the damaged grid. The voltmeter should read 12 volts. Move one probe toward the other one, checking every half-inch until the voltmeter reads 6 volts. This is the area of the grid that needs repair. Once you have found the break in the grid, switch off the defroster.

    2

    Wash the area around the break with a clean rag and rubbing alcohol. Be sure to get all the dirt and oil residue off the window and grid so the conductive paint will stick and give you a sound connection.

    3

    Apply masking tape to either side of the grid at the point of the break. Put the masking tape just on either side so that only the width of the grid is between the two pieces of tape.

    4

    Shake the conductive paint well and apply it to your taped area. Paint all along between the two pieces of tape so that you will be sure to fill any breaks in the grid.

    5

    Let the paint dry for 24 hours. Remove the two pieces of tape and discard them.

How to Fix a Scratch on an Acrylic Windshield

The most important thing, besides the engine, about your motorcycle or any other vehicle that has an acrylic windshield is the ability to see where you are going. An acrylic windshield also helps to protect you from possible debris that may be coming toward you. When there is a scratch in your shield, it may interfere with your visibility and ability to drive safely. Using these steps, you will be able to repair your acrylic windshield should you find a scratch in it.

Instructions

Gauging Scratches

    1

    The first thing you want to do is to investigate what kind of scratches on your acrylic windshield you are dealing with. Small, hairline scratches are easy to take off as compared to larger scratches. As a general rule, if you are able to put your fingernail into one of the scratches, you should probably consult a pro before trying the repair at home.

    2

    Using a mixture of warm water and mild soap, gently clean the acrylic windshield, making sure not to scrub too hard. If you scrub too hard, you may create more scratches. If you are unsure of what kind of fabric to use to clean your windshield, you can either use a special fabric bought through a motorcycle shop, an old T-shirt or even a cloth baby diaper. Using another piece of that fabric, dry off the windshield.

    3

    Using another piece of fabric, gentle apply the fine grade buffing solution to the outside of the acrylic windshield. Make sure to fill in all of the spaces where you are able to see scratches. Read the manufacturers label to see if there are any additional rules you need to follow. If you want to apply a polish, use a furniture polish on yet another piece of fabric. It also works to fill in any scratches that you may have missed.

How to Replace the Rear Shoes on a 94 Chevy 2500

How to Replace the Rear Shoes on a 94 Chevy 2500

Removing and replacing brake shoes from your vehicle is a simple process that nonetheless requires careful attention and expert tool and part manipulation. Poorly executing any step of the process can lead to brake failure. Consequently most mechanics advise you to save this process for experts or at least consult a mechanic before you begin. Replacing the rear shoes on your 1994 Chevrolet 2500 truck is a complicated but doable task.

Instructions

    1

    Remove the hubcaps and loosen the nuts on the rear wheels of your truck before you raise it up onto the jack. The weight of the truck will keep the wheel stable while you're cracking the nuts. If you attempt to loosen the nuts after you raise the truck onto the jack, it will be difficult to crack the nuts without turning the wheels.

    2

    Raise the 2500 on a 5-ton jack and support the truck with two jack stands. Though 2500s don't nearly approach 5 tons in gross weight, it is good to use a jack that can lift twice the weight of your vehicle.

    3

    Unscrew the cracked nuts on the driver's side rear wheel to remove the wheel entirely.

    4

    Cover the rear wheel's hub with a penetrating oil and let the oil work for several minutes. This will lubricate the hub and drum while you're working with it.

    5

    Remove the retaining clips holding the brake drum in place before unscrewing the four anchoring screws that attach the drum to the truck.

    6

    Pull the brake drum off the truck.

    7

    Use brake cleaner spray to remove excess oil, dirt and debris from the drum and the connection point on the truck.

    8

    Use the specialty shoe return ring removal tool to remove the old brake shoe return rings.

    9

    Hold the shoe's retaining pin down while removing the retainer springs.

    10

    Take the old shoes off the drum by pulling each side of the shoe outward from the drum as if you're opening the top of a box.

    11

    Attach the new brake shoes by holding each side open and sliding them over the brake drum.

    12

    Hold the shoe's retaining pin down while connecting the new retainer springs.

    13

    Reattach the new brake shoe return ring.

    14

    Reconnect the brake drum to your truck by rescrewing the anchoring screws and reclipping the retainer clips.

    15

    Repeat these steps for the other rear wheel of your truck.

Windshield Scuff Removal

Windshield Scuff Removal

A scuffed or scratched windshield is not only unsightly, its dangerous. Being able to see clearly out of your cars windshield is crucial to avoiding accidents, so its important to take care of scuffs and scratches as soon as they happen.

Considerations

    First of all, make sure its a scuff mark or scratch and not just dirt. Wash the windshield gently but thoroughly with soap and water, and if necessary, use an ordinary razor blade on an angle to remove any sap or sticky material. If you determine that the mark is indeed a scratch and its fairly deep, you may need to take the car to a professional. If the mark is a crack, it will simply keep expanding until you have no choice but to replace the windshield. If you find you need to take the car to a professional, check with your cars warranty to see whether such service is covered.

Gentle Abrasives

    Many scuff marks and scratches result from faulty or aging windshield wipers scraping across the glass. You can try any one of a number of abrasive recipes and see whether it helps remove the mark. One of the products most recommended by mechanics is cerium oxide, an orange powder you can find in auto stores or online. Wet a soft cloth or sponge and dip it in the oxide so that you make a paste on the cloth. Then rub the cloth in small circles, using pressure over the scuff marks, but keep checking your work so that you dont overdo it.

    Buy some jewelers rouge (iron oxide) for removing the scuff mark. It can be found in department stores, hardware stores, hobby shops or jewelry supply stores. Mix 1 ounce of iron oxide into a paste with 1 ounce glycerin and 1 ounce water. Put a small amount on a cloth and rub it onto the scratches, washing off with clear water from time to time to check your progress.

    If you have difficulty locating cerium oxide or jewelers rouge, try ultra-fine steel wool (0000 grade) and buff very gently followed by a glass scratch remover product from an auto supply store.

    Other abrasives you can find in your local grocery store may also work well. Bon Ami and Bar Keepers Friend are two lightly-abrasive products that are safe to use on most surfaces. Just as with the cerium oxide, take a little on a wet cloth and buff the scratch or scuff mark until its gone. If you have an electric buffer, you can use that instead of plain elbow grease. Toothpaste (not the gel kind) is another very fine abrasive that can be used with a cloth to remove marks.

DIY Kits

    Many auto supply stores sell windshield repair kits or windshield scratch or scruff remover kits that usually consist of a special glass-polishing wheel or pad and different grades of pumice powder. These kits come with full instructions, are easy to use and wont damage or distort the glass.

Professional Service

    If all else fails, or if it appears that your windshield damage is worse than you initially thought, take the car to an auto glass shop. There they will use a clear epoxy and careful buffing, or something similar, to fix the damage, and in most cases, its a relatively easy and inexpensive job.

How to Install the Back Brakes on a Ford Taurus

Standard rear brakes on the Ford Taurus were drum style, using twin shoes to apply friction to the inside of the drum surface. The friction stops the car. When the driver releases the brakes, the shoes retract away from the drum by springs. The shoes, springs, and drum are all regular maintenance items and can take the average backyard mechanic about thirty minutes to replace.

Instructions

    1

    Loosen the lug nuts on the rear tire on one side of the car. Do so with the lug wrench, turning counterclockwise.

    2

    Raise the rear of the car with the floor jack on the same side that you loosened the rear tire lugs, placing the jack head onto a frame rail toward the rear of the car, never on the body or suspension. Place a jack stand under the frame rail near the jack head for support.

    3

    Remove the wheel by removing the lug nuts completely, by turning counterclockwise. Pull the wheel from the hub and set it and the lug nuts aside.

    4

    Remove the drum by pulling it free of the hub, or turning the keeper screw counterclockwise. The drum will slide off of the brake assembly, exposing the shoes and internal workings.

    5

    Remove the shoes by levering off the long springs with a screwdriver, then turning the primary spring bolts counterclockwise. The shoes will slide directly away from the backing plate. Take this opportunity to inspect the wheel cylinder for leaks.

    6

    Replace the shoes by pressing them into place, then turning the spring bolt clockwise. Reattach the long springs using the screwdriver, levering them onto the hooks.

    7

    Resurface the drum material or use a new unit, and place it into position by sliding it over the shoes and brake assembly. Attach the keeper screw clockwise, if applicable.

    8

    Replace the wheel onto the hub. Replace the lug nuts and tighten hand tight by turning all lug nuts clockwise, with an alternating pattern. Tighten the lug nuts with the lug wrench in an alternating pattern--start with one nut, then skip the next in sequence, tightening the third, then the fifth, then the second, then the fourth. Do it all over again until all nuts are tight. Slide the jack stand away from the car. :Lower the vehicle by turning the floor jack's pressure screw counterclockwise.

    9

    Repeat the entire procedure on the opposite brake.

Problems With Parking Brakes Inside Rotors

Problems With Parking Brakes Inside Rotors

The parking brake is an essential safety device on automobiles and operates mechanically when the brakes fail or to safely hold an automobile in place when parked. Most parking brakes on later model vehicles utilize the rear brakes and rotors. A series of cables running from the pull handle or parking brake pedal is used to bypass the hydraulics of the normal braking system; but when the rotors have a problem, the parking brakes can fail.

Worn Rotors

    Since the rear rotors of the disc brakes are used for the parking brake system, the same problems that occur with the disc brakes happen with the parking brake. The parking brake cable controls the calipers of the rear brakes, and the rotors can wear down, preventing the calipers from applying enough pressure to the rotors to stop the vehicle. The rotors are a wearable component of the automobile and do need to be inspected each time scheduled maintenance is performed on the vehicle. The brake shoes wear a groove into the rotors under normal driving conditions; and if the rotors are not inspected periodically, the rotors will become worn.

Glazed Rotors

    The rotors on the brakes can become glazed and prevent the parking brake from working properly or slip. This glazing happens to the rotors when the braking system becomes too hot or overheats because the brake shoes are worn. A glazed brake rotor does not allow the brake shoes to hold tight because the rotor's surface has become smooth like glass. Once the parking brake is applied, the calipers will tighten the brake shoes against the rotors; but since the rotors are glazed, the parking brake will not hold the automobile in place. If the rotors are glazed from overheating, they can be machined down to bring the surfaces back or will need to be replaced.

Warped Rotors

    The parking brake will not hold the automobile if the rotors are warped. The rotors become warped when the automobile brakes are operated at an excessively high temperature which takes the rotors past glazing and to the point where their diameters warp. This rotor problem is created because of a problem with the brake shoes rubbing against the rotors during normal driving conditions. The heat builds up on the rotors, causing them to glaze and then warp. Once the rotors are warped, the brake shoes do not press down onto a flat surface because of the warping. Once the parking brake is engaged, the brakes will slip, allowing the automobile to roll freely. The rotors need to be replaced if they become warped.

How to Bleed the Brakes on a 1991 Nissan 300ZX

The Nissan 300ZX's history dates way back to 1970, when Datsun -- now Nissan -- released the 240Z. Until the 1984 release of the 300ZX, Datsun and Nissan introduced two other Z-cars, the 260Z and the 280Z. In 1984, the 300ZX came about and it lasted through 1996. The 1991 300ZX came standard with a 222-horsepower, 3.0-liter V-6 and had an optional turbocharged 3.0-liter engine that produced 300 horsepower. The disc brake system in the 1991 300ZX had a hydraulic fluid that carried the pressure created by the master cylinder to the brake calipers. When air gets in the hydraulic fluid, it can cause a soft-feeling brake pedal or even poor braking. Bleeding the 1991 300ZX's brakes will eliminate the air in the lines.

Instructions

    1

    Open the 300ZX's master cylinder reservoir and add DOT 3 brake fluid to the master cylinder reservoir until the fluid level reaches the "Max" line on the reservoir.

    2

    Wedge wheel chocks in front of the 300ZX's front wheels. Raise the rear of the vehicle, using a floor jack, and position jack stands under the vehicle's frame rails. Lower the 300ZX onto the jack stands.

    3

    Crawl under the vehicle and locate the bleeder valve -- the 1/4-inch metal fitting -- on top of the left-rear caliper. Press a 1/4-inch rubber hose on the bleeder valve and insert the free end in a small, clear container.

    4

    Fill the small, clean container with about two inches of DOT 3 brake fluid -- enough to submerge the free end of the hose.

    5

    Instruct your assistant to press and release the brake pedal until it feels firm -- 10 to 15 pumps -- then hold the pedal down. Open the bleeder valve by turning it about one turn with a combination wrench. Watch the end of the hose that's submerged in the brake fluid and see if bubbles appear when you open the valve.

    6

    Close the bleeder valve, with a combination wrench, and instruct your assistant to release the brake pedal.

    7

    Repeat Steps 5 and 6 until no air bubbles come from the hose.

    8

    Top off the master cylinder reservoir with DOT 3 brake fluid and repeat Steps 3 through 7 on the right-rear caliper.

    9

    Raise the 300ZX from the jack stands, using a floor jack, and remove the jack stands. Lower the Nissan to the ground.

    10

    Wedge wheel chocks behind the rear wheels of the Nissan. Raise the front of the 300ZX off the ground, using a floor jack, and position jack stands under the 300ZX's frame rails. Lower the Nissan onto the jack stands.

    11

    Repeat Steps 3 through 7 on the front calipers -- starting with the right-front caliper, then bleeding the left-front caliper. Top off the master cylinder with fresh DOT 3 brake fluid between bleeding calipers.

    12

    Raise the 300ZX from the floor jack and remove the jack stands. Lower the vehicle to the ground.

    13

    Check the brake fluid level in the master cylinder reservoir and fill it to about the midway point between the "Min" and "Max" lines on the master cylinder reservoir.

How to Repair a Power Window Switch in a Dodge Durango

Many models of the Dodge Durango and other vehicles use power windows in the doors that are operated by switches. Repairing a power switch that doesn't work can be a matter of replacing the switch itself or changing the wiring harness. How much work you have to do depends on exactly what needs replacing. This process can also vary depending on the exact year of your particular Dodge Durango.

Instructions

    1

    Disconnect the truck's negative battery cable at the terminal, loosening the clamp's nut with your wrench.

    2

    Pry out the power switch control from the inner door armrest using a trim stick and disconnect the electrical connector in the rear. Skip to Step 8 if this is all you need to replace.

    3

    Remove the screws for the door's inner trim panel if you need to get to the switch's wiring --- the Durango's screws are usually behind the door handle, behind the pull handle, up near the mirror and along the bottom edge.

    4

    Pull the panel up and off its clips to remove it, then peel back the plastic water shield.

    5

    Disconnect the wiring electrical connector from the regulator's motor and feed the wiring out the door.

    6

    Connect the electrical connector for the new wiring to the window regulator motor and feed it up toward the position of the control switch.

    7

    Press the water shield into position with its own adhesive and reconnect the inner trim panel with its clips and screws.

    8

    Connect the wiring to the window switch plate (old or new) and insert the switch controls in position on the trim panel --- usually above the pull handle and to the side of the main handle.

    9

    Reconnect the battery cable.

How to Change a Rear Windshield

How to Change a Rear Windshield

Changing a rear window, or as Auto Body Mart refers to as a vehicle's back light, requires several tools and materials. The steps involve removing the weatherstripping -- or its watertight adhesive liner that surrounds and seals the window in place. For a successful removal, have an assistant to help remove and install the glass with ease. Wear safety gear before working with glass and other hazardous material.

Instructions

    1

    Wear safety gear. Place utility gloves and goggles on before proceeding to remove and install glass.

    2

    From the outside, puncture any side of the weather-stripping rubber with a windshield knife. Feed the garage cable inside the slice you've made. With one person inside the vehicle and the other outside, begin to saw with the cable all around the adhesive rubber for removal.

    3

    If there is any weather stripping left from inside the vehicle, remove all traces of it with a windshield knife.

    4

    Press on and the loosen rear window from inside the car by adding pressure, it will be much easier to remove the glass from its threshold. Have an assistant stand outside of the car back light to catch the glass.

    5

    Remove any sticky substance from around the threshold with mild soap or a commercial cleaner. Wipe dry.

    6

    Apply primerless adhesive around the perimeter, and allow it to dry for 15 minutes before caulking urethane adhesive on top of the primerless adhesive.

    7

    Choose a rear window that matches the size and grade of the old window. Bead urethane adhesive along the perimeter of the rear glass itself. Have your assistant help you lift the rear glass inside the perimeter so that it fits onto the adhesive. Place pressure on the rear window for a few minutes so that the adhesive can set in place.

    8

    Let the rear window dry for 24 hours.

How do I Replace Aluminum Truck Topper Windows?

How do I Replace Aluminum Truck Topper Windows?

One of the primary functions of a truck topper window is to add more security for your materials. Broken windows, however, make this security void.

How to Replace a Windshield in a 2002 Grand Prix

How to Replace a Windshield in a 2002 Grand Prix

Replacing the windshield in your 2002 Grand Prix not only adds beauty to your car, it can also save your life. Before the 1970s, vehicles were made with steel, not fiberglass and other lighter materials common in cars today. Designers of the 2002 Grand Prix calculate the inherent strength of the windshield into the strength and safety of the car. A windshield installed incorrectly on a later model vehicle can quite literally kill you if you're involved in an accident. Follow these steps carefully to insure a correct and safe installation of the windshield.

Instructions

    1

    Inspect the broken windshield and the area around the windshield. Check for dents, cracks and corrosion. You must fix structure damage first.

    2

    Prepare the area around the broken windshield. Place a vinyl cloth on the interior and exterior of the car. Apply tape over any exterior vents near the windshield to protect the car from broken glass.

    3

    Remove the wiper blades with a puller tool.

    4

    Remove the trim around the outside windshield. The waterproof rubber can be removed with the removal tool. Insert the tool under the trim and pull towards you until all the rubber is removed.

    5

    Remove the adhesive material holding the broken windshield in place. Insert the windshield knife under the windshield and go around the windshield. The broken windshield should now be loose in the frame.

    6

    Remove the windshield. Attach the windshield puller to the windshield with the two suction cups.

    7

    Prepare the windshield mounting surface and new windshield. The area where it will be installed must be clear of all debris. Run the windshield scraper along the mounting surface and apply the bonding agent. Take the scraper knife and scruff the mounting areas around the new windshield. Apply the bonding agent.

    8

    Apply an ample supply of caulk around the mounting area of the car.

    9

    Install the new windshield using the windshield puller to position it on the mounting surface. After the bonding agent has dried, re-install the rubber trim around the windshield.

How to Change a Brake Caliper on a 1996 Acura

How to Change a Brake Caliper on a 1996 Acura

The disc brake calipers on a 1996 Acura feature internal hydraulic pistons that extend outward when the brake pedal is applied. This motion contacts the friction material of the brake pads to the flat surface of the brake rotors. Replacing the calipers is not a common repair unless the pistons are sticking or there is damage to the bleeder screws. The 1996 Acura uses front disc brakes but may also have rear disc brakes. Replacement calipers come with the pistons already compressed, so the only difference in procedure between the front and rear is attaching the parking brake assembly to the rear calipers.

Instructions

    1

    Set the Acura in gear or park on a level surface. Apply the parking brake if replacing a front caliper but do not apply the parking brake if replacing a rear caliper.

    2

    Place a wedge-shaped wheel brace behind one of the rear tires (for front caliper replacement) or in front of one of the front tires (for rear caliper replacement).

    3

    Loosen the wheel nuts on the tire with the faulty caliper using the wheel nut remover. Do not loosen the wheel nuts more than half a turn.

    4

    Lift the quarter panel of the Acura with the faulty caliper using a service jack. Raise the quarter panel up high enough to place a jack stand under the lift point located on the appropriate rocker panel and then lower the jack slowly to support the Acura onto the jack stand.

    5

    Remove the wheel nuts and tire assembly.

    6

    Clamp a brake hose crimp onto the hydraulic brake hose of the faulty caliper.

    7

    Remove the parking brake bracket retaining bolt with the ratchet and a metric socket (rear caliper only).

    8

    Place a drain catch pan beneath the caliper then remove the banjo bolt on the end of the brake hose from the caliper housing using a ratchet and a metric socket. Discard the copper washers on both sides of the banjo at the end of the brake hose. Align the drain pan, if necessary, to catch the slowly leaking brake fluid. The brake hose crimp will minimize the amount of fluid leaking from the brake hose.

    9

    Remove the upper and lower caliper bolts using the ratchet and a metric socket. Pry the caliper off of the caliper mount using a small angled pry tool.

    10

    Remove the brake hose plug from the replacement caliper and the replacement copper washers that come with it. Place the caliper over the brake pads, caliper mount and brake rotor.

    11

    Place one new copper washer onto the banjo bolt then insert the banjo bolt through the banjo of the brake hose. Place the remaining copper washer on the end of the bolt before hand-threading it into the caliper housing. Tighten the banjo bolt snug enough to squash/flatten the copper washers slightly but do not crush them. Remove the brake hose crimp.

    12

    Realign the upper and lower caliper bolts and hand-thread them into the caliper housing. Tighten the bolts snugly with the ratchet and metric socket.

    13

    Reattach the parking brake cable and retaining bracket bolt, then tighten the bolt with the ratchet and metric socket (rear brake caliper).

    14

    Loosen the bleeder screw on the replacement caliper with the ratchet and metric socket until brake fluid begins to drip into the catch pan. When there's a steady stream of fluid, close the bleeder screw and have an assistant get into the driver's seat of the Acura.

    15

    Check the brake fluid level in the master cylinder and top it off with DOT3 brake fluid then replace the cover.

    16

    Instruct your assistant to pump the brake pedal three or four times and then maintain downward pressure on the brake pedal. Loosen the bleeder screw to allow the air and fluid to purge from the bleeder screw until the brake pedal drops to the floorboard. Repeat this step until the brake pedal feels firm. Check the master cylinder after three or four bleeding sequences and top off with DOT3 brake fluid if necessary. Do not allow the master cylinder to run out of brake fluid or the suction cups could reverse internally and damage the cylinder.

    17

    Replace the tire and wheel nuts, then tighten the nuts in a crisscross pattern using the wheel nut remover until the tire and rim assembly are snug to the wheel hub. Lower the Acura quarter panel then torque the wheel nuts with the torque tool set at 80 ft.-lbs. and the metric socket, again, using a crisscross pattern.

How to Remove a Gas Tank Off of a 1990 Ski Doo Mach 1

If your idea of fun is racing over snow-covered hills at top-notch speeds, then the Ski Doo Mach 1 is the ski mobile for you. The 1991 Mach 1 was a reliable snowmobile. However, it does require maintenance and repairs from time to time. If the fuel tank on the Ski Doo ever does get damaged and springs a leak, or if you ever have to change the fuel pump, it may be necessary to remove the tank.

Instructions

    1

    Open the Ski Doo fuel tank, insert the siphon hose and use the hand pump to siphon the gas out of the tank into one or more gas cans.

    2

    Use a wrench to loosen the nuts holding the tank's fuel lines in place and then pull off the lines.

    3

    Use a socket set to loosen and remove the bolts that hold the fuel tank straps in place.

    4

    Lower the fuel tank down gently once the straps are loosened and then slide the tank up and out.

How to Replace the Brake Pads on a Ford F-150

The brake pads on the Ford F-150 are made to grip the brake rotors during braking, slowing and stopping the truck. The material on the brake pads is soft enough to provide a tacky grip on the metal rotors, while sturdy enough to endure the wear of everyday driving. The pads will eventually wear thin, requiring replacement to ensure safe driving. Ford recommends replacing your brake pads every 5,000 miles.

Instructions

    1

    Loosen the lug nuts on the wheels you intend to service. Use the lug wrench from the Ford wheel maintenance kit.

    2

    Lift the front of the vehicle with the jack, and place at least two jack stands beneath the frame of the truck. Lower the truck unto the jack stands.

    3

    Remove the lugs and front wheels from the truck.

    4

    Remove the caliper slide pin on the back side of one of the calipers with the 13mm socket and ratchet.

    5

    Lift the caliper from the caliper bracket on the rotor.

    6

    Pry the brake pad from the inside wall of the caliper with a flathead screwdriver. The pad has metal clips on the back that affix it to the caliper.

    7

    Place a worn brake pad against the caliper piston that extends from one of the inside wall of the caliper. Grip the caliper and the worn pad with locking pliers, and squeeze the piston into the side of the caliper. Remove the pliers and pad once the piston is completely opened on the caliper side.

    8

    Apply brake grease to the sides of the caliper, especially the side from which the piston extends.

    9

    Place the new pad on the inside of the caliper, and press it against the wall to secure the clips to the side.

    10

    Return the caliper to the caliper bracket and screw in the caliper slide pin.

    11

    Repeat Steps 4 through 10 to replace the other brake pad on the other side of the vehicle.

    12

    Replace the wheels onto the wheel bolts, and screw on the lug nuts.

    13

    Lift the truck enough to remove the jack stands. Lower the F-150 to the ground, and tighten the lug nuts with the lug wrench.

Problems With the E-Z-GO Brake System

Problems With the E-Z-GO Brake System

E-Z-GO has been a leader in light transportation since 1954. The company set out to build a better golf cart and now produces an extensive line of over 40 different models. E-Z-GO manufactures top-of-the-line golf carts as well as work vehicles, shuttles and various recreational vehicles. Older E-Z-GO models commonly end up with brake problems after extended use.

Total Brake Failure

    Many E-Z-GO cart owners have noted that their brakes have stopped working entirely and suddenly. When the owner pushed the brake pedal, it went all the way to the floor with no resistance. This is typically the result of a broken cable on the driver's side.

Sticking Brakes

    Some customers have reported sticking brakes that need to be pumped repeatedly in order to engage. This is often the result of a loose bolt on the backside of the backing plate. This bolt ensures proper tension on the brake shoes.

Recommendations

    Because E-Z-GO brake problems are fairly common, some E-Z-GO owners recommend replacing the brakes with four-wheel disc brakes or upgrading to independent hydraulic brakes, such as a Jake brake (a compression release engine brake) for added safety.

Seat Cowl Removal

Seat cowls are plastic trim pieces that are mounted around the bottom of the seats on several types of vehicles, including gas-powered scooters, some motorcycles and three-wheeled all terrain vehicles. They are most common, though, on gas powered scooters, like the Vespa or the Honda Metropolitan. Seat cowl removal will vary slightly from vehicle to vehicle. However, for the most part they are held in place by fasteners and screws. Removal will take about 30 minutes.

Instructions

    1

    Lift up on the seat and then use the socket set to remove the bolts holding the seat in place.

    2

    Locate the plastic fasteners that are placed along the perimeter of the plastic cowl. Push in on the center of these fasteners until they collapse and then pull them straight out by hand. The number of fasteners will vary depending on what sort of vehicle you are removing the cowl on.

    3

    Locate the screws along the inside of the seat cowl and take them out with a screwdriver.

    4

    Lift the seat cowl up and off the vehicle.

Parking Brake Spring Installation

Parking Brake Spring Installation

The braking system within a vehicle has many components, from drum brakes to disc brakes. But, the parking brake is vital in case of major brake failure, allowing the vehicle to stop before losing control to stop the vehicle.

Identification

    The parking brake system starts with the lever in the passenger compartment. It is attached to the rear drum brakes by cabling and long springs. When the lever is pulled, the mechanical assembly tightens to press the brake shoes against the drum for halting the car.

Installation

    If the parking brake springs need replacement, they can be installed without professional help. After removing the old springs, verify the parking brake shoes are positioned properly. Attach the spring to the strut, or compression bar, with the spring hook pointing to the ground. Then, attach the spring to the parking brake shoe, creating tension.

Considerations

    After the springs are installed, attach the parking brake cables to the parking brake lever to complete the mechanical assembly. The cabling needs lubrication on its back plate area to avoid friction and damage.

How to Replace the Rotor in a Ford Explorer

When your rotors become warped or worn down on your Ford Explorer, the result is a very obnoxious shudder every time you hit the brakes, usually accompanied by some thudding and screeching. If this sounds like your Explorer, then it's time to swap out the old rotors for new.

Instructions

    1

    Buy new rotors for your Ford Explorer at your local auto parts store or online. Replace all of the rotors at once or at least the front or rear pair of rotors at the same time for safe braking performance.

    2

    Raise your Ford Explorer and be sure to block the wheels to keep your vehicle from rolling while you work. Remove the tire and wheel assembly on the first wheel you intend to work on.

    3

    Remove the caliper mounting bolts with a socket wrench or air ratchet. If you can't slide the caliper off of the brake disc (rotor), you may need to use a c-clamp to compress the piston (especially in dual piston models) back to allow you to move the caliper.

    4

    Use mechanic's wire to suspend the caliper and attached brake line out of the way while you remove the old rotor. Don't let the brake line get disconnected from the caliper or the brakes will need to be bled.

    5

    Pull off the old rotor and then clean the area around the hub with a damp cloth. Apply a small amount of anti-seize lubricant to the hub flange and then put the new rotor into position on the hub.

    6

    Replace the caliper and brake line to their original positions and then fasten the caliper mounting screws with a torque wrench or an air ratchet with an appropriate adapter to 100 ft. lbs. (136 Nm).

    7

    Install the wheel assembly and tire. Repeat the process for each additional rotor. When you've finished, lower your Explorer, tighten the lug nuts with a torque wrench and pump the brakes until the pedal feels firm. Test drive your Ford Explorer to make sure that the rotor installation was successful.

How to Take the Rotors Off a 2002 Intrepid

The 2002 Dodge Intrepid was equipped with front disc brakes that did the majority of the stopping for the braking system of the car. Over time, these rotors wear down from normal use, and when it comes time to change the brakes, you can either get the existing rotors resurfaced, or replace them with newer models. No matter which way you go, you have to remove the rotors from the car first.

Instructions

    1

    Secure the front of the car on jack stands by lifting it up using the jack. Remove the front tires with the tire iron.

    2

    Unbolt the brake-caliper bracket from the front knuckle with the ratchet. Lift the bracket and caliper off of the rotor and hang it from the front suspension using the bungee cord. Make sure the brake line is free of any tension.

    3

    Look on the face of the rotor for any clips going around the wheel lugs. If equipped with the clips, pull them off the lugs using the needle-nose pliers. Hold the rotor with both hands and slide the rotor off of the knuckle.

How to Replace the Window in the Pontiac Vibe

How to Replace the Window in the Pontiac Vibe

The window on a Pontiac Vibe is mounted within the door. The window's regulator is a permanent fixture and can't be serviced without professional help; but it is possible to replace the window glass if needed. You need to get inside the door to remove and replace the window glass. Use extreme caution if you are replacing cracked or broken glass -- one of the more common reasons for replacing the glass.

Instructions

    1

    Roll the window down. Remove the window control. The easiest way is to work a cloth back and forth behind a manual crank to dislodge its clip, or to pry out the power switch and disconnect the electrical connector.

    2

    Pry the mirror trim cover off with a small flat screwdriver -- remove the manual handle with a Philips screwdriver first if needed -- and pry out the screw cover within the inner door handle.

    3

    Unscrew the door panel screws and then pry the panel off its clips with the trim stick or flat screwdriver. Lift the panel off the door, disconnect its electrical connectors and peel off the watershield.

    4

    Drill out the three rivets for the black door access plate and remove the plate.

    5

    Remove the mounting bolts for the window glass with a wrench and pull the glass up.

    6

    Lower the new glass into the door and fasten it within the door with its bolts.

    7

    Reconnect the door access plate, securing it with either rivets and a rivet gun or sheetmetal screws.

    8

    Reconnect the door trim panel with its clips and screws, then reconnect the trim panels and window controls.

How to Fix Moon Roof Leaks

A leaking moon roof can easily put a damper in your day when it rains. The leak is normally caused by a blockage in a water drain in the moon roof. Fixing the leak may be costly if you take it to an auto mechanic, but you should be able to carry out the fix yourself without too much difficulty.

Instructions

    1

    Dampen a towel with isopropyl alcohol. Clean the rubber and the areas around the opening of the moon roof with the damp towel.

    2

    Inspect the corners of the sunroof for blockage by looking closely at each corner. Push picture wire down each opening on each of the four corners to clear each opening of any blockage.

    3

    Spray compressed air in each opening on each of the four corners. Pour water down each opening on each corner of the moon roof to check if the leak persists. If the leak still occurs, contact an auto mechanic.

How to Replace Car Windows

Replacing the windows of a car is not only a costly affair, but also one which takes a lot of time. The good news is, you can do it yourself. So theres no need to lose patience on waiting for a repair shop to fix your window and no need to spend large amounts of money on the repair. Get together some simple tools from your toolbox and follow some simple steps to replace your car window efficiently.

Instructions

    1

    Buy a replacement window for your car. Be sure to base your purchase on the make, model, and year of the car.

    2

    Wrap a cloth around the end of the screwdriver to gently pry off the weather stripping from around the door frame.

    3

    Remove the panel from the inside of the door. Models are different in how they are attached. Some models have clips and some have screws. A screwdriver will be beneficial in both cases, either in unscrewing the screws or popping the clips off.

    4

    Clean any broken glass from inside the panel. Wear heavy work gloves to avoid injury.

    5

    Clean your new replacement window with the cloth. Be sure to clean off any debris so that it does not get into the door seals. This may prevent a tight fit between the car frame and the door.

    6

    Use the socket wrench to remove any bolts that may be in the way, such as from the vent window.

    7

    Consult the car's manual for the positioning guidelines of your particular vehicle before placing the window into the slot. Carefully place the window in the slot. Align the clips and secure them loosely.

    8

    Make sure the window is operating correctly by rolling it up and down a few times. If it is, securely tighten the clips.

    9

    Replace weather stripping and reattach the door panel.

How to Install a Windshield on a 1500 Goldwing

How to Install a Windshield on a 1500 Goldwing

Honda's GL 1500 Goldwing is a premiere touring bike, even though it went out of production in 2001. It's a well-built workhorse that will last for many years if well maintained. Sooner or later, however, the windshield is likely to take a stone from the road and need replacing. It's a job suitable for the intermediate mechanic, and it shouldn't take more than an hour or two. One thing is certain: the next time you get caught in a passing thunderstorm, you'll be glad you took the time to install a new windshield.

Instructions

Remove the Windshield

    1

    Raise both windshield adjuster levers to raise the windshield. Pull back the trim around the mirrors to expose the screws. Remove the two screws holding the black trim under the windshield garnish on each side. Remove the black trim. (This trim is not on the 1995 through 2000 bikes.)

    2

    Remove the two screws on each side of the windshield garnish. (The garnish is the trim that covers the front bottom section of window.) Stand in front of the bike and gently pull the garnish, tipping the top toward you to remove it.

    3

    Remove the five screws holding the windshield. Remove the five oval mounts beneath the screws. Make note of the position of each mount, since they are not identical. Remove the windshield

Install the Windshield

    4

    Set the windshield into position on the bike. Replace the five oval mounts, noting that the two outside mounts are deeper than the others. Replace the five mounting screws.

    5

    Stand in front of the bike, holding the garnish. Note that tabs on the bottom of the garnish fit into slots on the bike. Tip the garnish toward you and slide it into position, tabs first. Replace the mounting screws on each end of the garnish.

    6

    Replace the black trim and mounting screws on each end of the garnish. (This trim is not on the 1995 through 2000 bikes.) Fit the mirror trim back into position. Set the windshield adjuster levers according to your preference.

How to Replace a 1999 Hyundai Accent Brake Switch

The Hyundai Accent continues to be a popular model, primarily because of its low price and snappy performance. The 1999 Hyundai Accent brake switch is located under the driver's dashboard; however, it is mounted near the top of the brake pedal so some effort is needed to reach the mounting area. There are only two wires going to the switch and operation is very straightforward. When the brake pedal is pressed, the switch extends and the brake lights come on.

Instructions

    1

    Work your way under the driver's dash, or remove the lower dash cover by removing the two lower bolts and lifting it up and out of the way. While not absolutely necessary to remove this cover, it might make it easier and more accessible to reach the switch.

    2

    Pull out the switch. Shine the flashlight to the top of the brake pedal. Just to the rear of the pedal is a small bracket that the brake switch fits into. Reach behind and grab the switch, then pull it out. The switch is held in place by the bracket and the thread-like rings on the switch body. It makes for a tight fit, so some force may be needed to pull the switch out.

    3

    Unplug the wire connector.

    4

    Insert and adjust the switch. Push the wire connector onto the new switch, and push the switch into the switch mounting hole. Slightly depress the brake pedal and continue to push the switch to firmly seat it next to the switch stop on the pedal. Release the pedal and lightly tug upward to adjust the switch. You will hear the switch click into place as the final adjustment is made.

    5

    Replace the lower cover if it was removed.

    6

    Test the brake lights. Operate the brake pedal and have an assistant watch the brake lights to be certain of their operation.

How to Compress a Big Caliper Piston for the Disc Brakes on a 1993 Honda Accord

The front calipers of the 1993 Honda Accord contain the big caliper pistons. The rear calipers (on applicable rear disc brake models) are about half the size of the front calipers, thus the pistons are also much smaller. No special tools are required to compress the front caliper pistons on the Accord; by contrast, because the rear caliper pistons are integrated with the parking brake mechanism they must be screwed in clockwise to compress, which requires a special caliper retracting tool kit.

Instructions

    1

    Remove half the fluid from the master cylinder in the driver's side engine compartment on the driver's side firewall with a brake fluid baster and discard the old fluid. Replace the cover to the master cylinder.

    2

    Remove the lower caliper guide bolt of the caliper with a metric wrench on the 1993 Honda Accord (with the front axle elevated and the tires removed).

    3

    Pry the bottom of the caliper off of the lower bridge with a small pry tool and pivot the caliper upward away from the bridge bottom.

    4

    Place a small piece of plywood against the piston of the caliper, and tighten a C-clamp against the piston so the driving screw of the clamp is against the wood and the top of the clamp is against the inside housing of the caliper.

    5

    Tighten the clamp until the piece of wood and caliper piston are fully seated in the caliper piston bore. Loosen and remove the clamp.

    6

    Lift up any sections of the rubber caliper piston boot (surrounded the caliper piston) protruding outward past the caliper piston to release any trapped air inside the boot.

    7

    Reassemble the brake caliper and lower the Accord to the ground.

    8

    Pump the foot brake pedal several times until it feels firm. This motion will seat the brake pads to the rotor by extending the brake caliper piston outward. Top the master cylinder off with clean DOT-3 brake fluid and replace the cap.

How to Install a New Window for a Honda Civic

How to Install a New Window for a Honda Civic

A new window in your Honda Civic may mean changing the glass itself, replacing the window regulator that holds the glass or both. You need to install new window glass if the current glass is cracked or broken, and you likely need a new regulator if the current one does not align the glass properly. The replacement process is very much like other vehicles, but it may vary slightly depending on the exact year of the Civic.

Instructions

Removal

    1

    Detach the door's manual window crank if the door has manual windows, inserting a wire hook to disconnect its clip.

    2

    Remove the door and pull handles, prying off their trim panels and removing their screws with a screwdriver. Disconnect the electrical connector for the power window controls if equipped.

    3

    Pry the door trim panel off its clips with a large trim stick and lift the panel up off the upper door ridge.

    4

    Peel back the plastic shield on the door.

    5

    Raise the window if needed (reconnect the window control temporarily) until you can reach the window's bolts through the door frame holes. Remove the two bolts with your wrench, tilt the glass slightly and pull it up and out.

    6

    Disconnect the electrical connector on the window regulator if it uses power windows, then remove the regulator's four bolts (they are lined up near the center of the window like a tilted rectangle) and slide it out through the door's service hole.

Installation

    7

    Insert the window regulator through the service hole and connect its bolts.

    8

    Slide the window glass down into the door and connect it to the regulator with its bolts.

    9

    Push the plastic shield into place and then reconnect the trim panel onto the door. Reconnect the door handles with their screws.

    10

    Reconnect the window handle if needed.

How to Change the Rotors on a 1996 F150

How to Change the Rotors on a 1996 F150

Ford F150 brake rotors on the 1996 models mount the wheel to the vehicle and provide the friction surface for the brake pads to bear on. The rotor is mounted on a spindle with a pair of tapered roller wheel bearings to support the radial and lateral loads of driving. Brake rotors help to dissipate the heat generated by the brake friction and must maintain a machined, flat surface to maximize their braking power. Malfunctioning brake calipers can overheat the rotor and cause it to warp, and worn brake pads can grind away rotor material and ruin the finish on the rotor, making replacement of the rotor a necessity. To change the rotors on either side of the vehicle, use the same procedure.

Instructions

Removal

    1

    Remove the hubcap with the narrow end of the tire tool by inserting the tip of the tool behind the edge of the hubcap and then prying the hubcap off. Loosen the lug nuts a half-turn with the tire tool.

    2

    Elevate the truck with a jack and install the jack stands under the reinforced portion of the front axle. Release the jack to allow the jack stands to fully support the weight of the truck. Finish removing the lug nuts, then pull the wheel from the lugs.

    3

    Drive the caliper pins out of the caliper with a brass drift and a hammer.

    4

    Compress the caliper on the rotor with a c-clamp to make it release the rotor. Release the c-clamp and quickly remove the caliper from the rotor. Hang the caliper with a short bungee. Do not hang it by the brake line. Do not allow the brake line to become kinked or damaged.

    5

    Remove the grease cap located in the center of the rotor by prying the cap loose with a flat screwdriver to expose the wheel nut.

    6

    Straighten out the legs of the cotter pin with a pair of needle-nose pliers. Pull the cotter pin out of the lock nut and discard the pin.

    7

    Remove the spindle nut by hand. Pull the rotor partially off of the spindle and push it back on again. This will leave the outer bearing and washer exposed for easy removal. Remove the washer and bearing, then slide the rotor off the spindle.

Installation

    8

    Apply a thin layer of grease on the spindle. Pack the inner bearing and put it in place in the hub. Place the new seal into the recess in the back of the hub. Tap the seal into place with a hammer and a seal driver.

    9

    Carefully slide the new rotor onto the spindle. Pack the outer bearing and slide it onto the spindle and into the race on the front of the rotor. Slide the washer onto the spindle and let it rest against the outer bearing.

    10

    Install and tighten the spindle nut to 22 to 25 ft./lbs. with a torque wrench. Back the spindle nut off 1/8 of a turn, then tighten the nut as tightly as you can with your fingers.

    11

    Install the nut lock and seat it over the spindle nut. Insert the new cotter pin into the spindle. Bend the cotter pin up against the nut with the pliers. Install the grease cap with a hammer by tapping on the cap until it is fully seated.

    12

    Place the caliper back in place over the rotor. Lightly coat each caliper pin with anti-seize compound, then drive them into their channels until the lock tabs are engaged on both ends.

    13

    Install the tire. Reinstall the lugs nuts then tighten them to 100 ft./lbs. Lower the vehicle off the jack stands.

How to Install Steel Brake Lines

Installing steel brake lines yourself is not difficult. There is no need to take the car to an automotive repair shop because you can install the line in your driveway in just a few minutes. When there is a problem with your brake line such as a kink in the line, or a hole, you need to replace it. You cannot straighten a brake line with a kink without weakening the line, and if you attempt to plug the hole, it will not hold very long and you may even completely clog the line.

Instructions

    1

    Open the engine compartment and disconnect the negative battery cable. Unsnap the lid from the master brake cylinder. Drain the brake fluid from the cylinder using the turkey baster and place it in the drain pan for recycling. Place the wheel chocks in front of the front wheels, or behind the rear wheels depending on where the problem brake line is.

    2

    Lift the automobile using the automobile jack. Place a jack stand under the vehicle and raise it to the frame. Crawl under the car and locate the problem brake line. Thoroughly clean the brake line fittings with the wire brush to prevent contaminating the brake lines. Loosen the fitting with a wrench and disconnect the line.

    3

    Allow remaining brake fluid to drain into the drain pan. Loosen the other end of the line with the wrench and disconnect it, allowing the brake fluid to drain into the pan. Pull the brake line from the retaining clips and from under the car. Place a new brake line under the car and snap it into the retaining clips. Connect the fittings and tighten them with a wrench.

    4

    Remove the jack stand from under the car. Lower the vehicle to the ground. Refill the master cylinder with fresh brake fluid. Bleed the brake lines by having a helper to pump and hold the brake pedal while you open the bleeder valve with a wrench to expel the air from the brake lines. Continue with this procedure until the air is gone from all lines.

    5

    Add brake fluid as needed throughout the procedure to make sure the master cylinder stays full. Connect the negative battery cable and tighten the terminal nut with a wrench.
