Front 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 front of the vehicle, and support it with safety stands in the proper locations.
2. Remove the front wheels.
3. Remove the brake pads.
4. Check the thickness (A) of the brake pads (B). Do not include the thickness of the brake pad backing plate (C).
5. If the brake pad thickness is less than the service limit, replace all of the front brake pads as a set.
6. Clean the mating surfaces 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 front of the vehicle, and support it with safety stands in the proper locations.
3. Remove the front wheels.
4. Remove the brake hose bracket mounting bolts (A).
5. Remove the flange bolt (B) while holding the caliper pin (C) with a wrench being careful not to damage the pin boot, and pivot the caliper (D) up out of the way. Check the hose and pin boots for damage and deterioration.
6. Remove the brake pads (A) and the pad shims (B).
7. Check the hose and pin boots for damage and deterioration.
8. Remove the pad retainers (A), and check the caliper pin for free movement.
9. Clean the caliper bracket (B) thoroughly; remove any rust, and check for grooves and cracks.
10. Inspect the brake disc, and check for damage and cracks.
11. Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the retainers on their mating surfaces (indicated by the arrows) against the caliper bracket.
12. Install the pad retainers. Wipe excess assembly paste off the retainers. Keep the assembly paste off of the brake disc and brake pads.
13. Apply a thin coat of M-77 assembly paste (PIN 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. Contaminated brake discs or pads reduce stopping ability. Keep grease and assembly paste off the brake discs and brake pads.
14. Install the brake pads and pad shims correctly. Install the pad with the wear indicator (C) on the upper 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.
15. Push in the piston (A) so the caliper will fit over the brake pads. Check the brake fluid level. The brake fluid may overflow if the reservoir is too full. Make sure the piston boot is in position to prevent damaging it when pivoting the caliper down.
16. Pivot the caliper (B) down into position. Install the flange bolt (C), and tighten it to the specified torque while holding the caliper pin (D) with a wrench being careful not to damage the pin boot.
17. Install the brake hose mounting bolts (A), and tighten them to the specified torque.
18. Clean the mating surfaces of the brake disc and the inside of the wheel, then install the front wheels.
19. 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.
20. Add brake fluid as needed.
21. After installation, check for leaks at hose and line joints or connections, and retighten if necessary. Test-drive the vehicle, then recheck for leaks.
