Rear
WARNING:- Never use an air hose or dry brush to clean brake assemblies.
- Use an OSHA-approved vacuum cleaner to avoid breathing brake dust.
- Block the front wheels before jacking up the rear of the vehicle.
1. Block the front wheels, loosen the rear wheel nuts slightly, support the rear of vehicle on safety stands, then remove the rear wheels.
2. Release the parking brake.
3. Hold the caliper pins with a thin, open-end wrench, and remove the two caliper bolts and the caliper from the bracket.
CAUTION:
- Thoroughly clean the outside of the caliper to prevent dust and dirt from entering inside.
- Support the caliper with a piece of wire so that it does not hang from the brake hose.
4. Remove the pad shim and brake pads.
5. Using vernier calipers, measure the thickness of each brake pad lining.
Brake Pad Thickness:
- Standard: 7.5 - 8.5 mm (0.30 - 0.33 inch)
- Service Limit: 1.6 mm (0.06 inch)
NOTE: Measurement does not include pad backing plate thickness.
6. Remove the pad retainers.
7. Clean the caliper thoroughly; remove any rust, and check for grooves and cracks.
8. Check the brake disc for damage and cracks.
9. Make sure that the pad retainers are installed in the correct positions.
10. Apply Molykote M77 grease to the pad side of the shim. Wipe excess grease off the shim.
11. Install the brake pads and pad shim on the caliper bracket.
WARNING:
- When reusing the pads, always reinstall the brake pads in their original positions to prevent loss of braking efficiency.
- Contaminated brake discs or pads reduce stopping ability. Keep grease off the discs and pads.
NOTE: Install the inner pad with its wear indicator facing downward.
12. Rotate the caliper piston clockwise into the cylinder, then align the cutout in the piston with the tab on the inner pad by turning the piston back.
CAUTION: Lubricate the boot with rubber grease to avoid twisting the piston boot. If the piston boot is twisted, back it out so it sits properly.
13. Install the brake caliper.
14. Install and tighten the caliper bolts while holding the caliper pins with a thin, open-end wrench.
15. After installation, check for leaks at hose and line joints and connections, and retighten if necessary.
16. Depress the brake pedal several times to make sure the brakes work, then road-test.
NOTE: Engagement of the brake may require a greater pedal stroke immediately after the brake pads have been replaced as a set. Several applications of the brake pedal will restore the normal pedal stroke.
