01/11/2022 Q: Is it okay to leave the caliper/pads installed while cutting rotors using an on-car lathe?
A:
On-car lathes should never be used with the pads and calipers installed on the vehicle. The debris from cutting the rotors can contaminate the brake pads/calipers which can lead to other brake concerns and comebacks.

01/11/2022 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.
