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.

Inspection
1. Raise the front of the vehicle, and support it with safety stands in the proper locations.
2. Remove the front wheel.





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 brake pads as a set.

Replacement





1. Remove the flange 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 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 Molycote M-77 assembly paste (P/N 08798-9010) 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 pads reduce stopping ability. Keep assembly paste off the brake discs and pads.





8. 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.
9. Install the brake pads and pad shim 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.





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. Be careful not to damage the pin boots, install the flange 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, check for leaks at hose and line joints or connections, and retighten if necessary. Test-drive the vehicle, then check for leaks.
