REMOVAL PROCEDURE
GM replacement brake lining material is recommended for all vehicles to maintain the balance between front and rear brake performance. GM
replacement brake parts have been carefully selected to provide the proper brake balance for the purposes of stopping distance and control over the
full range of operating conditions. Installation of front or rear lining material with performance different from that of recommended GM replacement
parts can change the intended brake balance of this vehicle.
