• Q: How to Service and Repair Brake Discs on 2001 Chevrolet Impala?

  A: The refinishing of brake rotors only becomes essential when detecting certain required conditions which include corrosion, pitting, cracks, heat spots, excessive bluing discoloration, scores above maximum tolerances, lateral runout surpassing specifications or rotor thickness deviation exceeding required measurements. The Hub Cleaning Kit (J42450-A) should be used to remove rust at the brake rotor hub when needed for refinishing purposes. Inspect rotor surface wear and thickness before proceeding with brake rotor hub cleaning. Put the brake rotor onto the brake lathe while following its manufacturer directions but taking proper measures to secure vibration dampening attachments. Follow the lathe operation by bringing the tools into contact with rotor surfaces while checking for a proper mounting through the witness mark. The witness mark needs to reach three-quarters around the rotor before continuing with the process; otherwise, re-mount it. Follow the rotor refining protocol provided by the lathe manufacturer while measuring adjusted rotor thickness regularly until the minimum thickness limits are exceeded. The achievement of a non-directional surface requires users to follow specified speed settings through application of 120 grit aluminum oxide sandpaper when using non-directional finishing tools or 150 grit aluminum oxide sandpaper with a sanding block when finish tools are unavailable. Clean apply each finishing surface using denatured alcohol or an equivalent brake cleaner after finishing application. The brake rotor exit requires the Rotor/Drum Flange Resurfacing Kit (J41013) for removal of wheel bearing flange corrosion which prevents lateral runout and brake system pulsation.
