REMOVAL & INSTALLATION
- To remove the wheel, loosen all the lug nuts at least one full turn, before raising the car.
- Raise and safely support the vehicle.
- Remove the tire and wheel assembly.
- Remove the two caliper mounting bolts and remove the caliper from the knuckle.
- Using a piece of wire, support the caliper out of the way. DO NOT disconnect the brake hose or allow the caliper to hang from the brake hose.
- Remove the brake rotor from the vehicle.
- Install the rotor on the vehicle.
- Install the caliper onto the steering knuckle. Make sure the brake hose is not twisted.
- Tighten the mounting bolts to 74 ft. lbs. (100 Nm).
- Install the tire and wheel. Hand-tighten the lug nuts.
- Lower the vehicle, then tighten the lug nuts to 100 ft. lbs. (136 Nm).
- Pump the brake pedal several times to seat the pads against the rotor.
The brake pedal must be pumped prior to operating the vehicle or the vehicle will not stop on the initial pedal application.
- Check the rotor surface for wear or scoring. Deep scoring, grooves or rust pitting can be removed by refacing. This can be performed by your local machine shop or garage. Minimum thickness is stamped on the rotor, or see the brake specifications chart in this section. If the rotor is thinner than specification, after refinishing, it must be replaced.
- Check the rotor parallelism using a micrometer. It must vary less than 0.0005 in. (0.0127mm) measured at four or more points around the circumference. Make all measurements at the same distance in from the edge of the rotor. Refinish the rotor if it fails to meet this specification.
- Measure the disc run-out with a dial indicator. If run-out exceeds 0.002 in. (0.051mm) for 1982-85 models, 0.004 in. (0.10mm) for 1985-87 models, and 0.002 in. (0.051mm) for 1988-96 models and the wheel bearings are OK (if run-out is being measured with the disc on the car), the rotor must be refaced or replaced as necessary.
