The pin for the rear brakes is really frozen.  Used some WD40 but I only had a nail-set rather then a good size punch.  Couldnt get it to move at all.  


I was thinking about getting an air hammer but wasn't sure if this was the best tool for this or a tool I would get a lot of other use out of.  Is there a better tool/way to free this?

Have you tried heat? Try a heat gun.  The progressive heating and cooling will draw penetrating oil between the pin and the calliper bore.


If this fails, push the pads back and remove the whole caliper from the car.  Cut the pads off the pin with something like a Dremel with a V.small cutting disc.  This will allow you to grip the pin with a self grip wrench and try to turn it to get it moving.  It will also allow you to get the pin in a vertical alignment so that gravity will draw penetrating oil into the joint. You could make a small reservoir with SuGru around the pin hole and fill it with penetrating oil and leave it soak over night.


If you continue to bash the pin you will flatten the end and make it larger, then it will jam in the bore even more effectively than it has at present.
