Rear
Rear Brake Pad Inspection and ReplacementCAUTION: Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.
^ Avoid breathing dust particles.
^ Never use an air hose or brush to clean brake assemblies. Use an OSHA-approved vacuum cleaner.
Inspection
1. Raise the rear of the vehicle, and support it with safety stands in the proper locations.
2. Remove the rear wheels.
3. Check the thickness of the inner pad (A) and outer pad (B). Do not include the thickness of the backing plate.
4. If the brake pad thickness is less than the service limit, replace all the pads as a set.
Replacement
1. Remove the bolt (A) and brake hose (B) from the mounting bracket.
2. Remove the caliper bolts (C), and remove the caliper (D) from the caliper bracket.
3. Remove the pad shims (A) and pads (B).
4. Remove the pad retainers (A).
5. Clean the caliper thoroughly; remove any rust, and check for grooves and cracks.
6. Check the brake disc for damage and cracks.
7. Apply a thin coat of Molycote M-77 assembly paste (P/N 08798-9010) to the retainers on their mating surfaces against the caliper bracket.
8. Install the pad retainers. Wipe excess assembly paste off the retainers. Contaminated brake discs and pads reduce stopping ability. Keep assembly paste off the discs and pads.
9. Apply a thin coat of Molycote M-77 assembly paste to both sides of the pad shims (A), the back of the brake pads (B), and the other areas indicated by the arrows. Wipe excess assembly paste off the shim. Contaminated brake discs and pads reduce stopping ability. Keep assembly paste off the brake discs and pads.
10. Install the brake pads and pad shims correctly. Install the brake pads with the wear indicator (C) on the lower inside. If you are reusing the brake pads, always reinstall the brake pads in their original positions to prevent a momentary loss of braking efficiency.
11. Rotate the caliper piston clockwise into the cylinder, then align the cutout (A) in the piston with the tab (B) on the inner pad by turning the piston back so the caliper can be installed on the brake pad. Lubricate the boot with rubber grease to avoid twisting the piston boot. If the piston boot is twisted, back it out so it is positioned properly.
12. Install the brake caliper (C) and caliper bolts (D), and tighten the bolts to the specified torque.
13. Install the brake hose (E).
14. Press the brake pedal several times to make sure the brake works, then test-drive the vehicle.
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.
15. After installation, check for leaks at hose and line joints or connections, and retighten if necessary.
