Cutlass V6-191 3.1L VIN M SFI (1998)
Brake Pad: Testing and Inspection
1. Inspect the brake linings every 9654 km (6,000 miles).
2. Inspect the brake linings whenever removing the tire and wheel assembly, such as a tire rotation.
3. Check both ends of the outer pad by looking in at each end of the caliper. These are the points at which the highest rate of wear normally occurs.
4. Check 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.
5. Look down through the inspection hole in the top of the caliper in order to view the inner shoe.
6. 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 it is worn to within 0.76 mm (0.030 in) of any rivet head.
7. Replace all disc brake shoe and lining assemblies at the same time.
