The Brake Align™ Runout Correction Procedure diagnoses and locates the "stack-up" of tolerances and error in the spindle, hub, bearings, and rotor and fully corrects for lateral runout. First, the rotor is machined on your bench lathe. Then the rotor is secured on the hub and checked for runout. The "high-spot" is targeted. The V-notch of the Brake Align™ Runout Correction Plate is lined up with the "high-spot". THE JOB IS DONE RIGHT THE FIRST TIME. "COMEBACKS" ARE ELIMINATED.
