4. Mount the brake rotor to the brake lathe according to
the lathe manufacturer's instructions, ensuring that
all mounting attachments and adapters are clean
and free of debris.
5. Ensure that any vibration dampening attachments
are securely in place.
6. With the brake lathe running, slowly bring in the
cutting tools until they just contact the brake rotor
friction surfaces.
7. Observe the witness mark on the brake rotor. If the
witness mark extends approximately three-quarters
or more of the way around the brake rotor friction
surface on each side, the brake rotor is properly
mounted to the lathe.
8. If the witness mark does not extend three-quarters or
more of the way around the brake rotor, re-mount the
rotor to the lathe.
9. Following the brake lathe manufacturer's
instructions, refinish the brake rotor.
10. After each successive cut, inspect the brake rotor
thickness. Refer to "Brake Rotor Thickness
Measurement: ".
11. If at any time the brake rotor exceeds the minimum
allowable thickness after refinish specification, the
brake rotor must be replaced.

Application
Application
12. After refinishing the brake rotor, use the following
procedure in order to obtain the desired non-
directional finish:
a. Follow the brake lathe manufacturer's
recommended speed setting for applying a non-
directional finish.
b. Using moderate pressure, apply the non-
directional finish:
– If the lathe is equipped with a non-directional
finishing tool, apply the finish with 120-grit
aluminum oxide sandpaper.
– If the lathe is not equipped with a non-
directional finishing tool, apply the finish with a
sanding block and 150-grit aluminum oxide
sandpaper.
c. After applying a non-directional finish, clean
each friction surface of the brake rotor with
denatured alcohol, or an equivalent approved
brake cleaner.
13. Remove the brake rotor from the brake lathe.
14. Measure the assembled LRO of the brake rotor to
ensure optimum performance of the disc brakes.
Refer to "Brake Rotor Assembled Lateral Runout
Measurement: ".
15. If the brake rotor assembled LRO measurement
exceeds the specification, bring the LRO to within
specifications. Refer to "Brake Rotor Assembled
Lateral Runout Correction: ".
