   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.

THICKNESS

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