ok i drilled out those screws and the rotor is stiiillllll stuck on there. i would have tried banging on it with a hammer but i dont know what that will do to it. is there a trick to getting rusted on rotors off or is there any nuts/bolts im missing. i took off the tire, the brakes, then drilled out those two screws. is that it? i know my three lugs will hold for a while but i dont want to push my luck.......thanks
