3) Set a dial gauge 10 mm (0.39 in) inward from the disc rotor outer circumference. Rotate the disc rotor to check runout. If the runout of disc rotor
exceeds the service limit, resurface the disc rotor. After resurfacing, check disc rotor thickness as in step 4).
Disc rotor runout limit: 0.05 mm (0.0020 in)
4) Set a micrometer 10 mm (0.39 in) inward from the disc rotor outer perimeter, and then measure the disc rotor thickness. If the thickness of disc
rotor exceeds the service limit, replace with a new disc rotor.
