Runout

CAUTION: The rotor runout specification must be met to assure proper brake performance without premature vehicle return with shudder, pulsation or roughness complaints.

1. Remove caliper and caliper bracket. Brake Caliper

NOTES:
^ Make sure all mating surfaces between the hub flange and the rotor are clean and free of rust or contaminants to prevent an erroneous reading.
^ Mark stud and rotor hole with touch-up paint.

2. Install front disc brake rotors on wheel hubs and hold in place by using inverted lug nut and washer to seat front disc brake rotors to wheels hubs. Tighten lug nuts to 85 Nm (62 ft. lbs.).

Rotor Runout, Front:

3. Install dial indicator gauge.
4. Measure runout near the center of the the rotor braking surface.
5. If the runout is below 0.035 mm (0.0014 inch), remove gauge and reinstall the caliper and caliper bracket.

NOTE: The gauge can remain mounted at the same location for either measurement. However loosen the tension on the flexible indicator arm and move the gauge well out from the area and tighten while components are being removed or installed.

Hub Face Runout, Front:

6. If the runout is not within specification, remove the rotor and measure the hub flange mounting face outside of the stud circle.
7. If the runout of the hub flange exceeds 0.05 mm (0.002 inch), install a new hub assembly and repeat flange face runout measurement. Refer to Transmission and Drivetrain. Reinstall the rotor and repeat the rotor runout measurement.
8. If the runout of the rotor exceeds the specification but the hub flange is within specification, reindex the rotor and repeat the measurement.
9. If the rotor still exceeds the specification, resurface the rotor, repeat the runout measurement and reindex the rotor if necessary. Brake Rotor/Disc
10. Reinstall the caliper and caliper bracket.
