My '05 Legacy started getting hot rotors (does glowing red mean hot?) on the PF after a brake change. The top slide pin moved freely, but the bottom pin didn't move at all. After much heat, PB Blaster, and Kroil, the bottom pin turns freely with my fingers, but will not come out even with a hammer. Is there anything special about removing this pin? I think it has a rubber bushing on it. What else should I do to get this pin out?
