Brake Pad: Testing and Inspection

Inspect the brake linings every 9.654 km (6,000 miles) and any time that the wheels are removed (tire rotation, etc.). Check both ends of the outer shoe by looking in at each end of the caliper. These are the points at which the highest rate of wear normally occurs. However, at the same time, check the lining thickness on the inner shoe to make sure that it has not worn prematurely. Look down through the inspection hole in the top of the caliper to view the inner shoe. Whenever the thickness of any lining is worn to within 0.76 mm (1/32 inch) of the shoe at any point, disc brake shoe and lining assemblies should be replaced in axle sets. Front and rear disc brakes have wear indicators that make noise when the linings wear to a degree where replacement is required. The spring clip is an integral part of the outboard shoe and lining. When the lining is worn, the clip contacts the rotor and produces a warning noise.
