The brake rotors on the 1999 Isuzu Rodeo can require replacement for different reasons. A common culprit for damaged rotors are the brake pad wear indicators. When the brake pads reach a critical point of wear, the wear indicators become exposed and make contact with the rotor's surface. The scraping against the metal disc causes an audible alert that the pads should be replaced. Prolonged driving once the indicators begin to make contact with the rotors can lead to gouging of the rotor surfaces. Left alone, the rotors will be damaged beyond the point at which resurfacing can be used to remedy the damage. Replace badly scored rotors immediately.
Crack the lug nuts on the Rodeo's wheels with the lug wrench.2
Lift the vehicle and place jack stands beneath the frame to support the Isuzu while you remove and replace the rotors.3
Remove the caliper bolts with the 13 mm wrench. The bolts are located on the back side, near the outer edge of caliper.4
Lift the caliper from the rotor and rest the front brake caliper on the steering arm above the brake assembly. Place the rear brake caliper on an idle jack stand or suspend it with a bungee from the rear wheel well. The main goal is to not put stress on the connection between the brake line and the caliper by hanging the caliper by the line.5
Pull the rotors from the wheel bolts.6
Spray brake cleaner onto the new rotor and place it onto a piece of newspaper or paper towel on the ground. Spray the wheel hub and wheel bolts with brake cleaner.7
Brush the brake assembly area with the wire brush to rid the area of debris, rust, and leaked brake fluid.8
Wipe the rotors clean with a cloth towel and place them onto the wheel bolts.9
Return the calipers over the rotors and screw in the caliper bolts with the 13 mm wrench.10
Return the wheels to the Isuzu's wheel bolts and screw on the lug nuts by hand.11
Lift the vehicle to remove the jack stands. Lower the Rodeo's tires to the ground. Tighten the lug nuts with the lug wrench.
