OTiS Posted August 15, 2011 Posted August 15, 2011 iv got new pads and rotors for the front but cant get the bolts and screws that hold the rotor on to come out. iv tried wd40, and liquid wrench penetrating formula. along with a breaker bar and an impact screwdriver and neither will budge. i actually twisted a bit on the impact screwdriver attempting to break it free. do you guys know of anything that will break through the rust, dirt, grime, and loosen this shit up??
Xeryon Posted August 16, 2011 Posted August 16, 2011 Yea, drill the heads off. On the impact screw driver were you using the + bit? if so toss it. Use a dremel or cutoff wheel to cut a nice big slot in it and use the flat driver head. The + bits cam out unless you can maintain a ridiculous amount of pressure on it. The very nature of an impact driver allows it to bounce too much.

Xeryon Posted August 16, 2011 Posted August 16, 2011 Harbor freight and craftsman impact driver won't make a difference. It's a question of force. The design of a + bit allows for it to cam out when you put a large amount of rotational force into it. The slot is flat and won't push out at you when you torque it. Just drill them off or modify them to use the slot bit. All they do is hold the rotor steady when you have the wheel and caliper off. Once you have the caliper back on the rotor isn't going to move and putting on the wheel finishes holding it in place. You do need to get that caliper bolt off without breaking anything. Lots of PB over time and judicious amounts of heat.
airjordan223 Posted August 16, 2011 Posted August 16, 2011 I had the same problem. Use a torch and heat those bitches up, they spin right out.
