2004 Chevrolet Impala Brake Disc Parts Questions & Experts Answers

• Q: What Tools Are Required to Service and Repair Brake Discs, and What Considerations Should Be Taken into Account Before Refinishing Them on 2004 Chevrolet Impala?

  A: Performing disc brake repair work calls for having the Disc Resurfacing Kit (J 41013) and Wheel Hub Resurfacing Kit (J 42450-A). Brake technicians do not need to refinish disc brake discs during normal brake service because this practice remains unnecessary. New discs should also receive no refinishing treatment. Only perform disc refinement when the part meets specifications for thickness and shows damage types including severe thickness fluctuation and one of these problems: rust, cracks, heat marks, blueing spots, or severe surface marks. Always measure disc thickness before performing refinishing work. Perform a hub/axle and disc surface pre-treatment by applying the Wheel Hub Resurfacing Kit (J 42450-A) and Disc Resurfacing Kit (J 41013). Check the areas where the disc meets the brake lathe base then put your disc on the machine with proper hardware cleaned for operation. Place the rotating cutting tools on the friction section of the disc while the lathe runs to verify correct tool attachment. The disc requires refurbishing according to lathe maker guidelines while checking its thickness after every passing. The organization must replace the disc because it has gone beyond its permitted thickness after the resurfacing process. For a non-directional outcome use the tooling suggested speed and pick from non-directional finishing tools with 120 aluminum oxide sandpaper or sanding blocks with 150 aluminum oxide sandpaper. Clean the brake surfaces with denatured alcohol or brake cleaner and remove the disc from the lathe for measuring assembled LRO to guarantee good brake performance. The technician needs to resolve the issue when LRO values do not match the standard criteria.
