Steve,
You actually need 2 c clamps or 1 c clamp and a bar with the 2 pot calipers. If you push one piston in, the other one comes out. You can do it by hand, but it's much easier with some clamps.
Alan,
I've got a couple of clamps and you're welcome to come by. Lance should be there by 1:00 or so.
The mini-installfest is on!
