Tools Required
J 41013 Rotor Resurfacing Kit
Important: Do NOT refinish the brake drums in order to correct any of the following
complaints:
• Brake noise (growl/squeal) • Premature brake lining wear • Cosmetic or superficial corrosion of the drum braking surface • Drum discoloration • Severe scoring of the drum braking surface (groove depth in excess
of 1.5 mm (0.060 in) • Brake pulsation caused by the following: - Brake drum out of round - Corrosion or pitting that is deeper than the drum braking surface
- Use a micrometer in order to measure the largest diameter of the brake drum. If the largest diameter of the brake drum exceeds the brake drum maximum refinish diameter, do NOT refinish the brake drum. Replace the brake drum.
- Use the J 41013 (or equivalent) in order to THOROUGHLY clean the rust from the brake drum flange.
- Refinish the brake drum. Refer to the brake lathe manufacturer's operating instructions.
- After machining the brake drum, use 120 grit aluminum oxide sandpaper in order to create a non-directional braking surface.
- Clean the braking surfaces with denatured alcohol or with a suitable brake cleaner.
Important: Failure to obtain the best possible braking surface finish may cause the vehicle to stop with difficulty.
Notice: Improperly tightened wheel bolts or nuts can lead to brake pulsation and rotor damage. In order to avoid expensive brake repairs, evenly tighten the wheel bolts or nuts to the proper torque specification.
