Brake Rotor Refinishing
WARNING: This page is about a different car, the 2003 Oldsmobile Bravada, 2003 GMC Envoy XL, 2003 GMC Envoy, and 2003 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Tools Required: Wheel Hub Resurfacing Kit (J-42450-A), Rotor Resurfacing Kit (J-41013).
NOTE:
DO NOT refinish the brake rotors in order to correct any of the following complaints:
- Growl or squeal brake noise.
- Premature brake lining wear.
- Cosmetic or superficial corrosion of the rotor braking surface.
- Rotor discoloration.
NOTE:
Refinish the brake rotors ONLY when one or more of the following conditions exist:
- Groove depth in excess of specification.
- Severe scoring of the rotor braking surface.
- Brake pulsation caused by the following:
- Lateral runout in excess of specification.
- Brake rotor thickness variation in excess of specification.
- Corrosion or pitting that is deeper than the rotor braking surface.
- Use the Wheel Hub Resurfacing Kit in order to clean the wheel bearing/hub.
- Use a micrometer in order to measure the thinnest point of the brake rotor. If the thinnest point of the brake rotor exceeds the brake rotor minimum thickness, DO NOT refinish the brake rotor. Replace the brake rotor.
- Use the Rotor Resurfacing Kit in order to thoroughly clean the rust from the brake rotor flange.
- Refinish the brake rotor. Refer to the brake lathe manufacturer's operating instructions.
- After machining the rotor, use 120 grit aluminum oxide sandpaper and a non-directional rotor finisher, if available, in order to create a non-directional braking surface.
- Clean the braking surfaces with GM P/N 12377981, Canadian P/N 10953463, or equivalent brake parts cleaner.
NOTE:
Failure to obtain the best possible braking surface finish may cause the vehicle to stop with difficulty.
