Rear Brake Pad Inspection and Replacement
Rear Brake Pad Inspection and Replacement
Special Tools Required
- Brake caliper piston compressor 07AAE-SEPA101
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. Service and Repair
2. Remove the rear wheels.
3. Check the thickness of the inner pad (A) and the outer pad (B). Do not include the thickness of the backing plate.
4. If the brake pad thickness of any of the pads is less than the service limit, replace all the rear brake pads as a set.
5. Clean the mating surface of the brake disc and the inside of the wheel, then install the front wheels.
Replacement
1. Remove some brake fluid from the master cylinder.
2. Raise the rear of the vehicle, and support it with safety stands in the proper locations. Service and Repair
3. Remove the rear wheels.
4. Remove the flange bolt (A) while holding the caliper pin B with a wrench being careful not to damage the pin boot, and pivot the caliper (C) up out of the way. Check the hose and pin boots for damage and deterioration.
5. Remove the pad shims (A) and brake pads (B).
6. Remove the pad retainers (A).
NOTE: The upper and lower pad retainers are different. During installation, make sure the pad retainers are in their proper positions.
7. Clean the caliper bracket (B) thoroughly; remove any rust, and check for grooves and cracks.
Verify that the caliper pins (C) move in and out smoothly. Clean and lube if needed.
8. Check the brake disc/drum 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.
10. Install the pad retainers. Wipe excess assembly paste off the retainers. Keep any assembly paste off the disc/drums and brake pads.
11. Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the pad side of the shims (A), the back of the brake pads (B), and the other areas indicated by the arrows. Wipe excess assembly paste off the pad shims and brake pads. Keep grease off the brake disc/drums and brake pads. Contaminated brake disc/drums or brake pads reduce stopping ability.
12. Install the brake pads and the pad shims as shown. Install the brake pad with the wear indicator (C) on the bottom 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.
13. Mount the brake caliper piston compressor (A) on the caliper (B).
14. Press in the piston with a brake caliper piston compressor so the caliper will fit over the brake pads. Make sure the piston boot is in position to prevent damaging it when pivoting the caliper down.
NOTE: Be careful when pushing in the caliper piston; brake fluid might overflow from the master cylinder's reservoir. If brake fluid gets on any painted surface, wash it off immediately with water.
15. Remove the brake caliper piston compressor tool.
16. Pivot the caliper down into position. Install the flange bolt (C), and tighten it to the specified torque while holding the caliper pin B with a wrench. Be careful not to damage the pin boot.
17. Clean the mating surface of the brake disc/drum and the inside of the wheel, then install the front wheels.
18. Press the brake pedal several times to make sure the brakes work.
NOTE: Engagement 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.
19. Add brake fluid as needed.
20. After installation, check for leaks at hose and line joints or connections, and retighten if necessary.
Test-drive the vehicle, then check for leaks. Testing and Inspection
