Try some P&B lubricant. You can get it at any auto supply store. I use it at work all the time to loosen bolts. Just let it set for a while. It is great stuff.

What's never failed me is a soak in penetrating oil, followed by a hand impact wrench - the kind that accepts a 1/2" 6 point socket that you hit on the end with a hammer - you just keep bumping the end until the nut comes loose. It's a lot cheaper usually than buying air tools (unless you already have a compresser - then just buy the 1/2" pneumatic impact wrench from Harbor Freight for $16). If you don't have them, investing in some thick walled impact sockets help a lot too.

I use a good ratchet and socket or wrench, and a hammer. Just a few taps on the wrench or ratchet and the bolts come loose. I would try everything before using heat on the caliper bolts. shawn

eastwood has a nice impact/breaker bar. part#14509. its 99 bucks,but is ideal for this situation, as well as others. im sure you could possibly find one cheaper. it has the1/2" socket on one side, and a flat place to hit with a hammer on the opposite side, while you put pressure on the bar to loosen. but im with the others, pb lube is pretty awsome. and just my couple of pennies, when i come up on a tight frustrating bolt like this, i go buy a spare or two BEFORE i get things tore apart so im not walking to the parts store to get another.....you know, just in case it does break....you can always return it if not needed.
