How to service and repair the brake drum on Buick Century?

Currently performing routine brake system maintenance does not require drum refinishing until at least one of these conditions exists: extreme corrosion, pitting, cracking, heat spots, severe bluing discoloration, or scoring beyond maximum specification or radial runout beyond maximum specification. Check brake drums for these conditions before measuring their diameter when you remove tire and wheel assemblies. The J 41013 Rotor/Drum Flange Resurfacing Kit removes all corrosion from the brake drum flange before you follow the manufacturer's instructions to mount the brake drum on the lathe by ensuring vibration dampening attachments are properly installed. Check the witness mark while operating the lathe by placing the cutting tool against the brake drum friction surface. A properly mounted drum will show witness marks that extend for at least three-quarters of its surface area. The drum refinish process should follow lathe manufacturer guidance while you inspect each cut for diameter deviations and must replace the drum if refinishing extends the drum beyond specified tolerances. Use the specified speeds for your refinishing project when working on non-directional surfaces and use 120 grit aluminum oxide sandpaper if you have a non-directional finishing tool or 150 grit aluminum oxide sandpaper with a sanding block as an alternative when no tool is available. Wipe friction surfaces using denatured alcohol or equivalent brake cleaner after you apply the finish to them. Clear all remaining brake drum from the lathe machine then clean the wheel bearing flange with the J 42450-A Hub Cleaning Kit because not doing so may create lateral runout and brake system pulsation.
