Brake Pad: Description and Operation
GM replacement
brake pad material, or equivalent is recommended for all GM vehicles to maintain the balance between front and rear brake performance. GM, or equivalent replacement brake parts have been carefully selected to provide the proper brake balance for purposes of both stopping distance and controllability over the full range of operation conditions. Installation of front or rear brake pad material with performance different from that of the GM replacement parts recommended for this vehicle can change the intended brake balance of this vehicle.
