Brake Pad: Specifications

Inspect the brake linings every 9,650 km (3,000 mi) or any time the wheels are removed, for example in the case of tire rotation.

Check both ends of the outer lining 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 lining to make sure it has not worn prematurely. Some inboard shoe and linings have a thermal layer against the shoe, integrally molded with the lining. Do not confuse this extra layer with uneven inboard-outboard lining wear. Look down through the inspection hole in the top of the caliper to view the inner lining. Replace the shoe and the lining assemblies whenever the thickness of any lining is worn to within 0.76 mm (0.030 inch) of the shoe. Replace the riveted shoe and the assemblies when the lining is worn to within 0.76 mm (0.030 inch) of any rivet head. Always replace the disc brake shoe and the lining assemblies as complete sets.

Check the flatness of the linings. Place the inboard and the outboard lining surfaces together and check for a gap between the surfaces. Any gap should not exceed 0.13 mm (0.005 inch) at the center of the lining surfaces. This applies to both new and used shoe and lining assemblies.





The shoe and the lining assemblies have a wear indicator that makes noise when the lining are worn (2) and need replacement.
