Brake Disc Runout:
Service Limit: O.1 mm (0.004 in)
5. If the disc is beyond the service limit, refinish the rotor with an on-car brake lathe. The Kwik-Lathe produced by Kwik-Way Manufacturing Co. and the "Front brake disc lathe" offered by Snap-on Tools Co. are approved for this operation.

NOTE: A new disc should be ground if its run-out is greater than 0.10 mm (0.004 in.).
