MACHINING ROTORS
When you are finished cutting, loosen the cutting arm lock lever, and turn the dials counter clockwise so
they will clear the larger thickness of the second rotor. Loosen the draw bar knob and remove the lathe
from the adapter. Be careful not to bump either the rotor or the wheel with the cutting head as you dis-
mount the lathe. Take special care not to bump the tips against the rotor.
Before removing the adapter from the first side, measure and record the lateral run-out on the rotor. Also
measure and record the thickness to ensure that it is above “machine to” specification. You may com-
pare to factory specifications in the Pro-Cut Brake Spec Guide provided, or other reliable certified source.
When you have finished your measurements, be sure to clear the hub, caliper bracket, and speed sensors
of any brake chips, dust or debris.
Optional: With the motor running, finish sanding with a 150 grit sand-
paper on a sanding block on each side of the rotor for 1 minute will serve to improve the surface roughness
average (Ra) by up to 25%. Excellent surface finishes provide the least amount of initial brake noise and
the best customer satisfaction.
Cleaning the rotor surface after machining to remove all dust and debris is very important in the overall
quality of the brake job. Pro-Cut recommends using liberal amounts of warm water with a mild detergent
and drying thoroughly with clean towels to be certain all loose material is removed.
