  Q: What tools are required to service and repair the brake drum on Chevrolet Cavalier?

  A: The brake drum service process depends on Rotor/Drum Flange Resurfacing Kit J 41013 and Hub Cleaning Kit J 42450-A. You need to refinish brake drums only when they have severe corrosion, deep pits, cracks, overheating marks, excessive discoloration due to heat, scoring that goes beyond allowed levels or when radial runout surpasses specified limits. Start by unlatching the tires and wheels to measure brake drum dimensions while looking for heavy wear and runout imbalances across the surface. To prepare the brake drum for refinishing you need J 41013 and follow lathe manufacturer guidelines for attaching the brake drum to the resurfacing tool. Secure all vibration dampening attachments during the process. Turn on the lathe and let the cutting tool touch the outer brake drum surface; if the witness line shows up on three-quarters or more of the drum periphery the mounting process is correct. Use lathe manufacturer directions to work on the drum while checking its diameter in stages until you need to replace it if the diameter grows too large. Use either 120 grit non-directional sandpaper on a tool or 150 grit aluminum oxide sandpaper on a simple sanding block at specified speed settings to get a smooth uniform texture. Use denatured alcohol or similar products to clean every part of the brake surface before taking the drum away from the lathe. Use the bearing flange Hub Cleaning Kit (J 42450-A) according to instructions when you need it to prevent brake system effects.
