DISC ROTOR : Inspection and Adjustment

INSPECTION

Appearance

Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace it if necessary. Refer to BR "DISC ROTOR : Inspection and Adjustment".

Runout

  1. Fix the disc rotor to the wheel hub and bearing assembly with wheel nuts (2 points at least).
  2. Check the wheel bearing axial end play before the inspection.

    Refer to FAX "Inspection".

  3. Inspect the runout with a dial indicator to measure at 10 mm (0.39 in) inside the disc edge.

Runout (with it attached to the vehicle) : Refer to BR "Front Disc Brake".

Runout

  1. Find the installation position that has a minimum runout by shifting the disc rotor-to-wheel hub and bearing assembly installation position by one hole at a time if the runout exceeds the limit value.
  2. Refinish or replace the disc rotor if the runout is outside the limit even after performing the above operation.

CAUTION: If the thickness is less than wear thickness + 0.3 mm (0.012 in), replace the disc rotor. Refer to BR"BRAKE CALIPER ASSEMBLY : Removal and Installation".

Wear thickness : Refer to BR "Front Disc Brake".

Thickness

Check the thickness of the disc rotor using a micrometer. Replace the disc rotor if the thickness is below the wear limit. Refer to BR "Front Disc Brake".

Wear thickness : Refer to BR "Front Disc Brake".

Thickness variation (measured at 8 positions) : Refer to BR "Front Disc Brake".

Thickness

ADJUSTMENT

Burnish contact surfaces between disc rotors and brake pads according to the following procedure after refinishing or replacing disc rotor, or if a soft pedal occurs at very low mileage.

CAUTION:

  • Be careful of vehicle speed because the brake does not operate firmly/securely until pad and disc rotor are securely fitted.
  • Only perform this procedure under safe road and traffic conditions. Use extreme caution.
  1. Drive vehicle on straight, flat road.
  2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
  3. Drive without depressing brake for a few minutes to cool the brake.
  4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.
