Brake Pad

Inspect the brake linings every 10 000 km (6,000 miles) and any time the wheels are removed. Check the following:





^ Inspect the outer brake lining at each end of the caliper. The highest rate of wear occurs at this point.
^ Check the inner brake lining thickness for premature wear. Some inboard shoes and brake linings have a thermal layer against the shoe that is integral to the lining. Do not confuse this extra layer with uneven inboard-outboard brake lining wear.
^ Look down through the inspection hole on top of the caliper and inspect the inner brake linings. Replace bonded brake shoe and lining assemblies when the thickness of any lining is worn within 0.76 mm (0.030 inch) of the shoe. Replace riveted shoe and lining assemblies when the thickness of any lining is worn within 0.76 mm (0.030 inch) of any rivet head. Always replace the disc brake shoe and lining assemblies as a complete axle set.
^ Check the flatness of new or used brake linings. Place the inboard and the outboard brake lining surfaces together. Check for a gap between the brake lining surfaces. The gap should not exceed 0.13 mm (0.005 inch) at the middle of the lining surfaces.





The outboard brake shoe and lining assembly has a wear indicator (1) that contacts the rotor when the lining needs replacement (2) and the brakes are applied. This produces a loud scraping noise.
