Brake Pad Inspection

Inspect the brake linings at regular intervals, and any time the wheels are removed (tire rotation, etc.) The outer pad has a wear sensor which makes noise when the linings wear to the point of requiring lining replacement.





When any lining thickness is worn to within 0.76 mm (1/32 inch) of the pads or rivet, replace the pads in axle sets.

When inspecting the disc brakes, check both ends of the outer pads (1,3) by looking in at each end of the caliper. These points are where the highest rate of wear normally occurs. Also, check the inner pad lining to make sure that it has not worn prematurely. Look down through the hole in the top of the caliper to view the inner pad. Some inboard pads have a thermal layer against the pad, integrally molded with the lining. Do not confuse this extra layer with uneven inboard-outboard lining wear.
