2005 Cadillac XLR Parts Questions & Experts Answers

• Q: How to service and repair the Brake Disc using the J 41013 and J 42450-A kits on 2005 Cadillac XLR?

  A: For Brake Disc service and repairs use both the j 41013 disc resurfacing kit (J 41013) and the j 42450-a Wheel Hub resurfacing kit (J 42450-A). Regular maintenance of disc brake discs excludes any disc refinishing or new disc refinishing procedures. Refinishing procedures must be conducted on discs exhibiting adequate thickness and specific defects including excessive thickness variation or corrosion, cracks, blueing discoloration or scoring beyond maximum specifications. Use the j 42450-a to clean hub/axle flange and Brake Disc mating surfaces before proceeding to disc refinishing with the j 41013. Examine mating surfaces of the disc then place the disc onto the brake lathe and verify that all attachments are free from contaminants. Put the lathe into motion while you introduce the cutting tools onto the disc friction surfaces to check for a proper mounting by examining the witness mark. Follow the manufacturer's instructions to refinish the disc while inspecting the thickness after each cutting operation before possible re-mounting. The disc needs replacement once the minimum allowable thickness gets exceeded during the refinishing process. Applying a non-directional finish demands the use of 120 grit aluminum oxide sandpaper as a non-directional finishing tool or 150 grit aluminum oxide sandpaper with a sanding block while following the recommended speed settings. Clean the frictive areas with denatured alcohol or approved brake cleaner followed by disc removal from the lathe and lro measurement to confirm proper disc brake function with necessary adjustments for exceedances in specifications.
