Inspect the brake pads every 6,000 miles (9650 km) or any time the wheels are removed, for example in the case of tire rotation.


Object Number: 156302  Size: SH

Check both ends of the outer pad by looking in at each end of the caliper. The ends are the points where the highest rate of wear normally occurs. At the same time, check the thickness of the inner pad to make sure it has not worn prematurely. Some inboard shoes and pads have a thermal layer against the shoe, integrally molded with the pad. Do not confuse this extra layer with uneven inboard-outboard pad wear. Look down through the inspection hole in the top of the caliper to view the inner pad. Replace the brake pads whenever the thickness of any pad is worn to within 0.76 mm (0.030 in) of the pad or rivet head. Always replace the brake pads as complete sets.

    • The fastener tightening specifications are for dry, unlubricated fasteners.
    • Perform all of the service operations on a clean bench which is free of any mineral oil or other contaminants.
    • Use extreme care when working around the antilock components to prevent any damage or misalignment.
    • Pump the brake pedal until it is firm before moving the vehicle. Check the brake fluid level in the brake master cylinder after pumping the brakes. Refer to Master Cylinder Reservoir Filling in Hydraulic Brakes.
