A: This procedure applies to both front and rear brake discs. Some 2003 and later vehicles are equipped with an optional performance brake system, identifiable by the "Turbo" mark on each caliper. When ordering replacement pads or parts, specify the correct brake system. To inspect the brake disc, loosen the wheel lug nuts, raise and support the vehicle on jackstands, and remove the wheel. Reinstall the lug nuts to hold the disc in place, and if working on the rear brake disc, release the parking brake. Remove the Brake Caliper and pads, but avoid disconnecting the brake hose from the caliper to avoid bleeding the brakes later. Suspend the caliper out of the way with wire. Visually inspect the disc surface for score marks and other damage, addressing deep scoring by removing and refinishing the disc. Check for disc run-out with a dial indicator, and if it exceeds the allowable limit, refinish the disc. The disc should be resurfaced regardless of the indicator reading to ensure a smooth and flat surface, eliminating pulsation. Check the disc thickness with a micrometer to ensure it meets the minimum allowable thickness. For removal, take out the front disc by removing the caliper mounting bracket and the lug nuts holding the disc in place, using bolts to force a stuck disc off the hub if necessary. To install the disc, position it over the wheel studs, install the mounting bracket (for front discs), and tighten the bolts to the specified torque. Install the Brake Pads and caliper, tightening the guide pins to the correct torque. Install the wheel, lower the vehicle, and tighten the lug nuts. Pump the brake pedal to bring the pads into contact with the disc, and check the brake operation before driving the vehicle.
