Loosen the wheel lug nuts, raise the vehicle and support it securely on jackstands. Remove the wheel and reinstall the lug nuts to hold the disc in place. Remove the brake caliper. It's not necessary to disconnect the brake hose. After removing the caliper guide pin(s), suspend the caliper out of the way with a piece of wire. Don't let the caliper hang by the hose and don't stretch or twist the hose. On all except double-pin non-family calipers, remove the outer brake pad. Visually inspect the disc surface for scoring and other damage. Light scratches and shallow grooves are normal after use and may not affect brake operation, but deep score marks over 0.015-inch require disc removal and refinishing by an automotive machine shop. Be sure to check both sides of the disc. If pulsating has been noticed during application of the brakes, suspect disc run out. To check disc run out, mount a dial indicator with the stem resting about 1/2-inch from the outer edge of the disc. Set the indicator to zero and turn the disc. If it does, the disc should be refinished by an automotive machine shop. Professionals recommend resurfacing of brake discs regardless of the dial indicator reading. At the very least, if you elect not to have the discs resurfaced, deglaze them with sandpaper or emery cloth. The minimum wear (or discard) thickness is also cast into the inside of the disc. The disc thickness can be checked with a micrometer. Remove the lug nuts you installed to hold the disc in place during inspection. The discs on some models are equipped with retaining washers to prevent them from slipping off while the caliper is removed; if the discs on your vehicle are so equipped, remove the washer with needle-nose pliers and discard it. Slide the disc off the threaded studs. Place the disc in position over the threaded studs. Install the caliper and brake pads. Tighten the caliper guide pin(s). Install the wheel and lug nuts, then lower the vehicle to the ground. Tighten the lug nuts. Depress the brake pedal a few times to bring the brake pads into contact with the disc. Bleeding of the system isn't necessary unless the brake hose was disconnected from the caliper. Check the operation of the brakes carefully before driving the vehicle in traffic.
