In fact most major OEMs are now recommending against resurfacing the rotors. GM goes as far as to state that a .060" deep groove is acceptable, which is odd because the old standard was to not remove more than .030" from each face. I try to test drive each car that comes in for a brake check and if it isn't vibrating I don't cut them.
