Clean disc thoroughly, and remove all rust. Use wheel nuts and suitable flat washers to hold disc securely against hub, then mount a dial indicator to brake and measure runout at 0.4" (10 mm) from outer edge of disc.

If disc is beyond service limit, refinish brake disc with an on-car brake lathe. See DISC BRAKE SPECIFICATIONS .
