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

•	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 in) of the shoe. Replace riveted shoe and lining assemblies when the thickness of any lining is worn within 0.76 mm (0.030 in) 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 in) at the middle of the lining surfaces.

•	Check the brake linings for taper. Measure one of the linings at both ends. Compare the measurements. Replace the linings if the difference is greater than 0.15 mm (0.006 in). Repeat the measurement procedure on each lining.

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