Brake Rotor Surface and Wear Inspection
- If the inboard friction surface of the brake rotor is not accessible, remove the brake pads. Refer to Front Disc Brake Pads Replacement or/and Rear Disc Brake Pads Replacement .WARNING: Refer to Brake Dust Warning .
- Clean the friction surfaces of the brake rotor with denatured alcohol or an equivalent approved brake cleaner.
- Inspect the friction surfaces of the brake rotor for the following Braking Surface Conditions:
- Heavy rust and/or pitting.
- Light surface rust can be removed with an abrasive disc. Heavy surface rust and/or pitting must be removed by refinishing the rotor. Refer to Brake Rotor Refinishing .
- Cracks and/or heat spots.
- Excessive bluing discoloration.
- If the friction surfaces of the brake rotor exhibit one or more of the Braking Surface Conditions, the rotor requires refinishing or replacement. Refer to Front Brake Rotor Replacement (15 inch Brake System J67 and J93) , Front Brake Rotor Replacement (16 inch Brake System J60) , Rear Brake Rotor Replacement or Brake Rotor Refinishing .
