REMOVAL & INSTALLATION
See Figures 1, 2, 3 and 4
- Raise the vehicle and support it safely.
- Remove the wheel and tire assembly from the rotor face, being careful not to damage or interfere with the caliper bleeding screw fitting.
Handle the rotor and caliper carefully as to prevent deformation, nicking, scratching and/or contamination of the rotor.
- Remove the caliper anchor plate bolt, then remove the caliper assembly from the rotor. Position the caliper aside and support it with a length of wire. Do NOT allow the caliper to hang by the brake hose.
- Remove the rotor from the hub assembly by pulling it off the hub studs. If additional force is required to remove the rotor, apply rust penetrator on the front and rear rotor/hub mating surfaces, then strike the rotor between the studs with a plastic hammer. If this does not work, attach a 3-jaw puller and remove the rotor.
If excessive force must be used to remove the rotor, it should be checked for lateral run-out before installation.
- Check the rotor for scoring and/or other wear. Machine or replace, as necessary. If machining, observe the minimum thickness specification.
- If a new rotor is being installed, remove the protective coating from the rotor with Carburetor Tune-Up Cleaner D9AZ-19579-AA or equivalent before installation. If the old rotor is being installed, make sure the rotor braking and mounting surfaces are clean.
Failure to clean rust and foreign debris from the rotor and hub mounting faces when installing a new or used rotor, will result in high lateral run-out, which will speed up the development of brake roughness, shudder and/or vibration.
- Apply a small amount of Silicone Dielectric Compound D7AZ-19A331-A or equivalent to the pilot diameter of the rotor.
- Install the rotor on the wheel hub assembly.
- Install the caliper and caliper anchor bolts on the rotor, then tighten the bolts to 85 ft. lbs. (115 Nm).
- Install the wheel and tire assembly, then hand-tighten the lug nuts.
- Lower the vehicle, then final tighten the lug nuts to 85-105 ft. lbs. (115-142 Nm). Pump the brake pedal before moving the car to position the brake shoes and linings.
Check the disc brake rotor for scoring, cracks or other damage. Rotor run-out should be measured while the rotor is installed, but rotor thickness (or thickness variation) may be checked with the rotor installed or removed. Use a dial gauge to check the rotor run-out. Check the rotor thickness to make sure it is greater than the minimum allowable thickness, and check for thickness variations using a caliper micrometer.
