Loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands. Remove the wheel and install the lug nuts to hold the disc in place, releasing the parking brake if working on the rear brake disc. Remove the
Brake Caliper without disconnecting the brake hose, suspending it out of the way with a piece of wire after removing the caliper bolts, then take off the caliper bracket bolts and remove the bracket. Inspect the disc surface for score marks and damage; while light scratches and shallow grooves are normal, deep scoring over 0.039-inch requires disc removal and refinishing. Check both sides of the disc, noting that severe wear from neglected brake pads necessitates disc replacement. To check disc runout, place a dial indicator about 1/2-inch from the outer edge, set it to zero, and turn the disc, ensuring the reading does not exceed the allowable runout limit; if it does, the disc should be refinished. It is recommended to resurface the discs whenever the pads are replaced to ensure a smooth finish and flat surface, eliminating brake pedal pulsation. If not resurfacing, remove the glaze from the surface with sandpaper or emery cloth using a swirling motion. Ensure the disc is not machined to a thickness under the specified minimum allowable refinish thickness, which can be checked with a micrometer. Remove the lug nuts that were installed to hold the disc in place, then take out the Phillips-head screws from the disc and slide it off the hub; if the rear disc is difficult to remove, address the
Parking Brake Shoes by removing the plug and rotating the adjuster to back them away from the drum surface. Place the disc in position over the threaded studs, install the caliper and tighten the bolts to the specified torque, bleeding is only necessary if the brake hose was disconnected. For a rear disc installation, adjust the parking brake shoes, then install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the specified torque.
