You can try rotating the piston with either mole grips or slip joint pliers, whilst pushing the piston with a G clamp. Obviously be careful not to pinch the pistons rubber seal. They always seem to corrode where the hex socket goes.

		Well, I finally heard the grinding noise meaning the end of my rear brakes. 
		 I disassembled the brakes and discovered only one bad pad, and a stuck 
		guide pin.  I turned the rotors, and fixed the guide pins.  Now the 
		problem:  I was anticipating cutting a Sealy cube in half (already had one 
		from previous vehicles) but saw a worn out hole in the center of the caiper 
		piston.  I remembered from a post a couple of days ago that a 12 mm inside 
		hex socket was required.  So I picked one up when I went to get the brake 
		pads.  It seems like it wants to fit, but just turns inside the hole 
		without spinning the piston.  Any suggestions?

		I thought the calipers for my Isuzu truck were made of 24K gold, but I now 
		realize they were only gold plated, while the Audi calipers are actually of 
		24K gold.  I really don't want to have to buy new ones.
