Tools Required
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 |
| • | 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
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. Replace the brake rotor.
- Use the
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.
Important: Failure to obtain the best possible braking
surface finish may cause the vehicle to stop with difficulty.
- 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.
