Front Disc Rotor

INSPECTION
1) Secure the disc rotor by tightening the five wheel nuts.





2) Set a dial gauge on the disc rotor. Turn the disc rotor to check runout.

CAUTION: Securely fix the disc rotor to hub.

NOTE:
^ Make sure the dial gauge is set 10 mm (0.39 inch) inward of rotor outer perimeter.
^ If the runout of disc rotor exceeds the limit, check for abnormal free play at hub bearing and runout in the thrust direction. If the hub bearing is okay, replace the disc rotor.

Disc rotor runout limit: 0.075 mm (0.0030 inch)








3) Measure the disc rotor thickness. If the thickness of disc rotor is below runout limit, replace the disc rotor.

NOTE: Make sure the micrometer is set 5 mm (0.20 inch) inward of rotor outer perimeter.
