FAQ for Brake Disc Repair
Q: How do on-car lathes react to Axle Float? Does the play affect the machining of the rotor, either surface finish or LRO?
A:
Because the Pro-Cut on-car lathe adjusts in a live mode while spinning the hub/rotor, the dynamics of a floating axle are effectively eliminated. Once the lathe is compensated, there is no difference in the cutting/surface finish and LRO are just the same as with a non-floating axle.

21/02/2022 Q: What is the Brake Pad and Rotor Burnishing procedure?
A:
First, select a smooth road with little or no traffic. Then accelerate the vehicle to 48 km/h (30 mph). Using moderate to firm pressure, apply the brakes to bring the vehicle to a stop. Do not allow the brakes to lock. Repeat steps 2 and 3 until approximately 20 stops have been completed. Allow sufficient cooling periods between stops to properly burnish the brake pads and rotors.
