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. If the lug nuts don't contact the disc when screwed on all the way, install washers underneath. Remove the brake caliper without disconnecting the brake hose, and suspend it out of the way with a piece of wire. Visually inspect the disc surface for score marks and other damage; light scratches and shallow grooves are normal, but deep scoring over 0.039-inch (1.0 mm) requires disc removal and refinishing. Check both sides of the disc, as severe wear indicates the need for replacement. If pulsating occurs during brake application, suspect disc runout. To check runout, place a dial indicator about 1/2-inch from the outer edge of the disc, set it to zero, and turn the disc; the reading should not exceed the allowable limit. Resurfacing the discs when replacing brake pads is advisable to ensure a smooth finish and eliminate brake pedal pulsation. The disc must not be machined to a thickness below the specified minimum allowable thickness, which can be checked with a micrometer. Remove the two caliper mounting bracket bolts and detach the caliper mounting bracket. Remove the lug nuts holding the disc in place and take the disc off the hub. If a rear disc is stuck, remove the rubber plug from the parking brake adjuster hole and use a small screwdriver to turn the star wheel and retract the parking brake shoes. Place the new disc over the threaded studs, install the caliper mounting bracket over the disc, and tighten the bolts to the specified torque. Install the caliper and tighten its bolts to the specified torque. Finally, install the wheel, lower the vehicle to the ground, and tighten the lug nuts to the specified torque. Depress the brake pedal a few times to bring the brake pads into contact with the disc, and check the operation of the brakes carefully before driving.
