RUNOUT

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

Maximum runout (with it attached to the vehicle) : Refer to See: Specifications\Front Brake Rotor/Disc.

NOTE:
Before measuring, make sure that wheel bearing axial end play is within the specification. Refer to See: Maintenance\Wheels and Tires\Wheel Hub\Testing and Inspection\Front Wheel Hub.

  1. 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.
  2. If runout is outside the specified value after performing the above operation, turn the disc rotor using Tool.

Tool number : 38-PFM90.5

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