BRAKE TECH: Rotor Runout Solutions

I was recently working on a vehicle with pressed-in wheel bearings. After the bearing was was replaced, I measured the runout and endplay. The endplay was within specs, but with .004″ of runout, something was wrong. It was not the bearing, but the axle stub/hub. If I would have let it go, it would have been a pulsation comeback.

If you think the only solution would have been to replace the hub and destroy the new bearing in the processes, you are wrong. The best solution was to use a runout correction plate from BrakeAlign. The plate brought the runout to within specification of .002″.

Here is a great video explaining the plates.
