Inspect the brake linings every 9654 km (6,000 miles).
Inspect the brake linings whenever you remove the tire and wheel
assembly, such as a tire rotation.
Inspect both ends of the outer pad by inspecting at each end of
the caliper. These are the points at which the highest rate of wear normally
occurs.
Inspect the lining thickness on the inner shoe for premature wear.
The inboard shoe and linings may have a thermal layer against the shoe which
is molded with the lining. Do not confuse this layer with uneven inboard
outboard lining wear.
Look down through the inspection hole in the top of the caliper
in order to view the inner shoe.
Replace the disc brake shoe and lining assemblies when the thickness
of any lining is worn to within 0.76 mm (0.030 in) of the shoe.
For riveted shoe and lining assemblies, replace the lining if the lining
is worn to within 0.76 mm (0.030 in) of any rivet head.
Replace all of the disc brake shoe and lining assemblies
at the same time.
