Brake Rotor Refinishing
WARNING: This page is about a different car, the 2003 GMC Sonoma, 2003 GMC Jimmy, 2003 Chevrolet S10 Pickup, and 2003 Chevrolet Blazer. However, it is still accessible from the selected car via links, so may be relevant.
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.
- Groove depth in excess of specification.
- Severe scoring of the rotor braking surface.
- Brake pulsation caused by lateral runout, brake rotor thickness variation and/or corrosion or pitting that is deeper than the rotor braking surface.
- Use the Wheel Hub Resurfacing Kit (J-42450-A) 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. See DISC & DRUM BRAKE SPECIFICATIONS .
- Use the Rotor Resurfacing Kit (J-41013) 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 brake parts cleaner (GM P/N 12377981) or equivalent .
