Frozen Brake Pins

Well I have stripped my front break caliper pins.  Any ideas to removing them?  Is some sort of reverse thread easy-out my next step?  I have tried penetrating fluids, heat and impact socket so far..

Thanks in advance

This worked for me once.

  Use a penetrant. Put a blunt punch in the hole that will bottom out (largest punch that fits). Hit it a couple times pretty hard , then tap on it a little. Have a cup of coffee(?) and hit it again. An easy out of some type should remove it. If it stops hard , run it back in after lubing it . Hit it again and try again.

As a last resort, if everything else fails, remove the caliper, and if need be grind away the loops in the pads so that you can get a pipe wrench on the pin and back it out that way.  And when you put in your new pins be sure you have anti-seize on there

This is a great idea.

Yeah, and if you have a small enough pipe wrench--Rigid makes a 6"--you might get away with not grinding the pads off, or just one of them.  Or a good bite with the right pair of vise grips might do it, I don't know.  Probably need to put the caliper in a bench vise (with protection) or clamp it to the bench.  This, in conjunction with an allen (if there's anything left to the hex socket) or with an easyout wedged in there as pictured, and you shall get the victory.
