inside the disc edge.
Runout limit: Front Disc Brake.
(with it attached to the vehicle)

NOTE:
Before measuring, make sure that wheel bearing axial end play is within the specification. Testing and 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.
Tool number: 38-PFM-90.5

THICKNESS






Check thickness of the disc rotor using a micrometer. Replace disc rotor if thickness is under the wear limit.
Standard thickness: Front Disc Brake.
