Runout Check







Rotor Run-out Check:





NOTE: Whenever brake front disc brake hub and rotor has been separated from hub face, clean any rust or foreign material from mating surface on hub face and front disc brake hub and rotor. Failure to do this may result in increased lateral runout of the front disc brake hub and rotor and brake pulsation.

Install front disc brake hub and rotors on hubs and hold in place by using inverted wheel lug nuts and washers to seat front disc brake hub and rotors to hubs. Tighten wheel lug nuts to 115-142 Nm (85-105 ft lb).

Using a dial indicator D78P-4201-B, or equivalent, measure front disc brake hub and rotor lateral runout as shown. The dial indicator should be centered on brake surface. Rotate front disc brake hub and rotor while measuring runout. If runout is greater than 0.08mm (0.003 inch), front disc brake hub and rotor must be repositioned (indexing) on hub to obtain the lowest possible runout.
