I have a 2002 Grand Cherokee. I have the caliper off, but the bracket that surrounds the rotor is stuck. The two 18 mm bolts on the back are seized. I've broke one cheap socket already. I don't want to use a torch because of all the tubing around. I have sprayed it with PB blaster. Just looking to see if anyone has any ideas. I really don't want to have to drill it out.
