Anyone ever have problems driving the Brake Pad pins out? Doing a rear brake job and I have one on each side that is giving me fits! I was able to easily remove the other pin on each side. I have PB Blaster'd the pins they are definitely stuck. Using a punch that I custom ground down to the exact diameter to fit the pins. I just can not drive out these pins. I don't want to damage the calipers with heat obviously. It's getting to the point where I may have to remove the caliper and have the pin pressed out. Thoughts and suggestions? Thanks in advance for your assistance.
