Brake Pad: Service and Repair

Front 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.

Replacement





1. Remove the bolt (A), and pivot the caliper (B) up out of the way. Check the hose and pin boots for damage and deterioration.





2. Remove the brake pad shims (A) and brake pads (B).





3. Remove the pad retainers (A).
4. Clean the caliper thoroughly; remove any rust, and check for grooves and cracks.
5. Check the brake disc for damage and cracks.
6. Apply a thin coat of M-77 assembly paste to the retainers on their mating surfaces against the caliper bracket.
7. Install the pad retainers. Wipe excess assembly paste off the retainers. Contaminated brake discs and brake pads reduce stopping ability. Keep assembly paste off the brake discs and brake pads.





8. Apply a thin coat of 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 a arrows.
Wipe excess assembly paste off the shim.
Contaminated brake discs and brake pads reduce stopping ability. Keep paste off the brake discs and brake pads.
9. Install the brake pads and pad shim correctly. Install the brake pads with the wear indicators (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.





10. Push in the piston (A) 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.
11. Pivot the caliper down into position. Being careful not to damage the pin boots, install the bolt (B), and tighten it to the specified torque.
12. Press the brake pedal several times to make sure the brake works.

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.

13. After installation, cheek for leaks at hose and line joints or connections, and retighten if necessary.
14. Install the front wheel, then test-drive the vehicle.
