VISUAL

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

RUNOUT

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

positions).

2. Inspect runout using a dial gauge placed 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-5, "Inspection"

.

3. When runout exceeds limit value, displace mounting positions of

disc rotor by one hole. Then find a position of the minimum value for runout.

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

THICKNESS

Check thickness of the disc rotor using a micrometer. Replace disc

rotor if thickness is under the wear limit.
