Brake shoes may contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.
REMOVAL & INSTALLATION
See Figures 1 and 2
- Remove the wheel cover.
- To remove the wheel, loosen all the lug nuts at least one full turn, before raising the car.
- Raise and support the car, then remove the front wheel.
- Remove the Allen head caliper mounting bolts and remove the brake caliper.
- Remove the caliper from the knuckle and suspend from a length of wire. Do not allow the caliper to hang from the brake hose.
- Pull the rotor from the knuckle.
- Place the rotor onto the steering knuckle.
- Place the caliper assembly into position on the rotor, then tighten the mounting bolt to 28 ft. lbs. (38 Nm) for 1982-84 models and 38 ft. lbs. (51 Nm) for 1985-96 models.
- Install the tire and wheel, then tighten the lug nuts by hand.
- Lower the car and tighten the lug nuts to 100 ft. lbs. (136 Nm).
- Pump the brake pedal several times to seat the pads against the rotor.
- 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 specifications after refinishing, it must be replaced.
- Check the rotor parallelism with 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.
