Brake Rotor/Disc: Testing and Inspection
Runout Check
NOTE: The procedure for checking rotor runout and thickness is the same for the front and rear rotor. If there is a specification difference between the
front and rear rotor it will be designated as such in the specifications of the following procedure.
Checking Brake Rotor For Runout
MEASURING ROTOR
On-vehicle rotor runout is the combination of the individual runout of the hub face and the runout of the rotor. (The hub and rotor runouts are
separable). To measure runout on the vehicle, remove the wheel and reinstall the lug nuts tightening the rotor to the hub. Mount Dial Indicator,
Special Tool C-3339 with Mounting Adapter, Special Tool SP-1910, or equivalents on steering arm. Dial indicator plunger should contact braking
surface of rotor approximately 10 mm (0.393 inches) from outer edge of rotor. Check lateral runout on both sides of rotor. Lateral runout of the
rotor should not exceed 0.13 mm (0.005 inch).
