Brake Rotor Refinishing
Brake Rotor Refinishing
^
Tools Required
-
CH-47661 On-Vehicle Brake Lathe
Important 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
Refinish the brake rotors ONLY when 1 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
1. 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.
2. Use the CH-47661 to refinish the brake rotor. Refer to the brake lathe manufacturer's operating instructions.
Important Failure to obtain the best possible braking surface finish may cause the vehicle to stop with difficulty.
3. 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.
4. Clean the braking surfaces with GM P/N 12377981 (Canadian P/N 10953463) or equivalent, brake parts cleaner.
