Inspection

VISUAL

Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace if necessary.

RUNOUT

1. Attach the disc rotor to wheel hub using wheel nuts at two or more positions.

2. Inspect runout using a dial gauge. Set the dial gauge to measure at 10 mm (0.39 in) inside the disc edge.

NOTE: Before measuring, make sure that wheel bearing axial end play is within the specification. Refer to FAX-6, "Inspection".

3. When runout exceeds limit value, displace mounting positions of disc rotor by one hole. And then find a position of the minimum value for runout.

4. If runout is outside the specified value after performing the above operation, turn the disc rotor using Tool.

THICKNESS

Check thickness of the disc rotor using a micrometer. Replace disc rotor if thickness is under the wear limit.
