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.

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





3. Hold the caliper pin (A) with a wrench, being careful not to damage the pin boot. Remove the caliper bolt (B) with another wrench, and pivot the caliper (C) up out of the way. Check the brake hose and pin boots for damage and deterioration.





4. Remove the pad shims (A), retainers (B), and brake pads (C).





5. Using vernier calipers, measure the thickness of each brake pad lining. The measurement does not include the brake pad backing plate (A) thickness.
6. If the brake pad thickness is less than the service limit, replace the front pads as a set.
7. Clean the caliper thoroughly; remove any rust, and check for grooves and cracks.
8. Check the brake disc for damage and cracks.





9. Install the pad retainers (A).





10. Apply Molykote M-77 assembly paste (P/N 08798-9010) to the brake pad side of the shims (A) and back of the brake pads (B). Wipe excess paste off the pad shim. Contaminated brake discs or brake pads reduce stopping ability. Keep assembly paste off of the brake discs and brake pads material.
11. install the brake pads and pad shims 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.





12. 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.
13. Pivot the caliper (B) down into position, being careful not to damage the pin boot. Hold the caliper pin (C) with a wrench, being careful not to damage the pin boot. Install the caliper bolt (D), with another wrench, and torque it to the proper specification.
14. Press the brake pedal several times to seat the pads/pistons and restore brake pedal height.
15. After installation, check for leaks at hose and line joints or connections, and retighten if necessary. Test-drive the vehicle, then check for leaks.
