Brake Pads Replacement Delco 3400

The use of GM brake pad material will help to maintain a balance between the front and the rear brake performance. In addition, the use of GM brake pad 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 brake pads or rear brake shoe 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.
