1) Check bearing axial end play and hub runout before disc rotor runout limit inspection.
2) Secure the disc rotor by tightening five wheel nuts.
3) Set a dial gauge 10 mm (0.39 inch) inward of rotor outer perimeter. Turn the disc rotor to check runout. If the disc rotor runout is above specified
value, after resurfacing, check disc rotor thickness as in step 4.
Disc rotor runout limit: 0.075 mm (0.0030 inch)
4) Set a micrometer 10 mm (0.39 inch) inward of the rotor outer perimeter, and then measure the disc rotor thickness. If the thickness of disc rotor is
outside the service limit, after resurfacing, check disc rotor thickness as in step 4.
