REMOVAL & INSTALLATION
See Figure 1
- Raise and safely support the vehicle.
- Remove the wheel and tire assembly.
- Remove the parking brake rear cable and conduit from the parking brake lever at the disc brake caliper using a pair of pliers.
- Remove the cotter pin and guide pin.
- Remove the caliper locating pin cover and remove the locating pin.
- Lift the rear disc brake caliper off of the anchor plate.
- Secure the caliper using wire to prevent damage to the brake hose.
- Remove the inner and outer disc brake pads.
- Remove the 2 bolts securing the anchor plate. Remove the anchor plate.
- Remove the retainers on the wheel studs securing the brake rotor to the hub (if not already removed).
- Remove the brake rotor.
- Inspect the brake rotor surfaces for scoring, wear or other damage. Machine or replace the disc brake rotor as necessary.
- If the rotor is being replaced, make sure that the new rotor is thoroughly cleaned of its protective coating.
- Lubricate the area of the wheel hub that the rotor fits to with a suitable grease.
- Install the rear disc rotor onto the wheel hub using new retainers.
- Fit the caliper anchor plate and secure with the 2 bolts after applying 1 drop of threadlock sealer to the threads of each bolt.
- Torque the retaining bolts to 43 ft. lbs. (59 Nm).
- Reinstall the inner and outer disc brake pads.
- Reinstall the rear disc brake caliper.
- Fit the caliper locating pin and torque to 30 ft. lbs. (41 Nm).
- Reinstall the caliper locating pin cover.
- Reinstall the guide pin and the cotter pin.
- Reinstall the parking brake rear cable and conduit onto the parking brake lever.
- Adjust the parking brake by operating the parking brake control several times.
- Reinstall the wheel and tire assembly. Torque the lug nuts to 62 ft. lbs. (85 Nm).
- Lower the vehicle.
- Pump the brake pedal several times to achieve a good pedal before attempting to move the vehicle.
- Road test the vehicle and check the brake system for proper operation.
See Figures 2 and 3
Rotor thickness should be measured any time a brake inspection is done. Rotor thickness can be measured using a brake rotor micrometer or Vernier caliper. Measure the rotor thickness in several places around the rotor. Compare the thickness to the specifications chart found at the end of this section.
The run-out of the brake rotor should be checked any time a vibration during braking occurs. Excessive run-out can be caused by a build-up of rust scale or other particles on the rotor or hub surfaces. Remove the rotor and thoroughly clean the hub and rotor-to-hub mounting surface on the back of the rotor. Mount a dial indicator to a suspension member and zero the indicator stylus on the face of the rotor. Rotate the rotor 360 degrees by hand and record the run-out.
Compare measurements to the brake specifications chart. If the thickness and run-out do not meet specifications, replace the rotor.
