Brake Pads Replacement Rear

Linings

The use of GM brake lining material will help to maintain a balance between the front and the rear brake performance. In addition, the use of GM brake lining material will provide the proper brake balance for the purposes of stopping distance and control over the full range of operating conditions. The installation of any front or rear lining material with a performance different from that of the suggested GM replacement parts for this vehicle may change the intended brake balance of this vehicle.

Removal Procedure

  1. Remove the caliper. Refer to Brake Caliper Replacement . Do not disconnect the brake hose as in Caliper.

  2. Object Number: 156335  Size: SH
  3. Suspend the caliper.
