Loosen the wheel lug nuts, raise the vehicle, and support it securely on jack stands. 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 under them. Remove the brake caliper without disconnecting the brake hose, and suspend it out of the way with a piece of wire, ensuring it doesn't hang by the brake hose. Visually inspect the disc surface for score marks and other damage; light scratches and shallow grooves are normal, but deep scoring requires disc removal and refinishing by an automotive machine shop. Check both sides of the disc, as severe wear indicates the need for replacement. To check disc runout, place a dial indicator about 1/2-inch from the outer edge of the disc, set it to zero, and turn the disc, ensuring the reading does not exceed the specified allowable runout limit; if it does, refinishing is necessary. 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 under the specified minimum thickness, which is cast into the underside of the front discs and on the outside of rear discs; measure the thickness with a micrometer. Remove the two caliper mounting bracket bolts and detach the mounting bracket. Remove the lug nuts holding the disc in place and slide the disc off the hub, cutting off any pressed-metal retaining clips on the wheel studs if present. Place the disc in position over the threaded studs, install the mounting bracket, and tighten the bolts to the specified torque before installing the brake pads. Install the caliper onto the mounting bracket, tightening the bolts to the specified torque, then install the wheel and lug nuts. Lower the vehicle 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 the vehicle.
