Machining ("turning") the rotors (discs) on an automotive brake job is fairly routine. This should '''not''' be done on a motorcycle. The rotors are much thinner, and you'll either end up with a rotor that's too thin for specs or warped from the heat. Rotors are extremely important for your safety. Replacing, rather than trying fix it on the cheap, is the way to go if you have a problem one.

Rotor runout (warpage) is measured with your motorcycle. Lightly squeeze the brake lever at 15 mph. If you feel pulsing, the runout is too great and the rotor must be replaced.
