Rear Brake Pad Inspection and Replacement

CAUTION: 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 brake pad backing plate.





4. If the brake pad thickness is less than the service limit, replace all the pads as a set.

Replacement
1. Raise the rear of the vehicle, and support it with safety stands in the proper locations.
2. Remove the rear wheels.
3. Remove the brake hose mounting bracket (A).





4. Remove the flange bolts (B) while holding the pin (C) with a wrench, being careful not to damage the pin boot, and remove the caliper (D). Check the hose and pin boots for damage and deterioration.
5. Remove the pad shim (A) and pads (B).





6. Remove the pad retainers (A).





7. Clean the caliper thoroughly; remove any rust, and check for grooves and cracks.
8. Check the brake disc for damage and cracks.
9. Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the retainers on their mating surfaces indicated by the arrow against the caliper bracket (B).
10. Install the pad retainers. Wipe excess assembly paste off the retainers. Keep any assembly paste off the discs and pads.
11. Apply Molykote M-77 assembly paste (P/N 08798-9010) to both sides of the shim (A), the back of pads (B), and the other areas indicated by the arrows. Wipe excess assembly paste off the shims and pads. Contaminated brake discs or pads reduce stopping ability. Keep grease off the brake discs and pads.





12. Install the brake pads and pad shims correctly. Install the pad with the wear indicator (C) on the inside. If you are reusing the pads, always reinstall the brake pads in their original positions to prevent a momentary loss of braking efficiency.
13. Install the brake hose mounting bracket (A).





14. Rotate the caliper piston (B) clockwise into the cylinder, then align the cutout (C) in the piston with the tab (D) on the inner pad by turning the piston back. 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.
15. Install the caliper. Install the flange bolts (E), and tighten it to the specified torque while holding the pin (F) with a wrench. Be careful not to damage the pin boot.
16. Press the brake pedal several times to make sure the brakes work.

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.

17. After installation, check for leaks at hose and line joints or connections, and retighten if necessary. Then test-drive the vehicle.
