If the rotor was removed during caliper service, the inner hub and hub flange must be cleaned before remounting (See Figure 9). To clean the
corrosion build-up on the rotor hub, use the 80 grit sanding disc J-41013 (or equivalent) on an air/electric drill motor.
NOTE:
It is very important that this cleaning process be done any time the rotor is removed from the hub. This is a leading cause of rotor runout which
leads to brake pulsation.
