Brake Rotor/Disc: Testing and Inspection
Front
INSPECTION
1. Check front wheel bearing play and axial 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 the rotor outer perimeter. Turn the disc rotor to check runout. If the disc rotor runout 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 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
exceeds the service limit, replace with a new disc rotor.
