Brake rotor specs are specified by the manufacturer. It is measured with a micrometer and if too thin via specs, will overheat causing a serious brake fade and loss of braking ability. Other problems could be that the rotor overheats and either warps or breaks~neither good. Turning the rotors is a process of rough cut and smooth cut that is supposed to take minimal amounts of metal off to make it an even surface for your brake pads to brake against. Most manufacturers today produce rotors that are not really able to be turned. So new rotors made be the only answer if yours are bad.
