2003 Buick Century Brake Disc Parts Questions & Experts Answers

• Q: What tools are required to refinish a Brake Disc on 2003 Buick Century?

  A: Two essential kits needed for brake disc refinishing are the Rotor Resurfacing Kit (J 41013) and Wheel Hub Resurfacing Kit (J 42450-A). Start work only when the brake disc meets minimum thickness requirements and will stay over those specifications after reconditioning. Refinish disc brakes only when their thickness varies more than what the specifications allow and shows excessive rust or pitting along with cracks, heat spots, or heavy scuff marks. Use J 42450-A Wheel Hub Resurfacing Kit first to clean rust from hub/axle flange surface. Then clean brake disc mating and mounting areas using J 41013 Rotor Resurfacing Kit. Set the brake disc on the brake lathe following assembly directions and verify that all parts remain free of impurities during the process. Lower the lathe cutting tools into contact with the disc surface layers while checking if the tool bits align. If necessary, re-mount the disc. Use the lathe per instructions to resurface the disc by checking its thickness after every step. When the disc reaches its predetermined thickness limit during refurbishing it needs to be replaced immediately. Use the recommended speed setting and sand the disc with 120 grit aluminum oxide sandpaper to create a non-directional finish when using a non-directional finishing tool. A sanding block and 150 grit aluminum oxide sandpaper are needed to achieve the same result if the machine lacks this feature. Use denatured alcohol or brake cleaner to clean the surface friction areas before removing the disc from the lathe for lateral runout measurement. This checks if the brake performance meets requirements. When the LRO measurement deviates from standard requirements our team takes required steps to fix the issue.
