First off, do you have the cap off the master cylinder in the engine compartment? You shouldn't need to open the bleeder valve and I really don't recommend it since it gives you a chance of getting water in the line.
Make sure the cap is off, get some WD40 and lube up inside the sleeve around the piston, then (prefferably in another vehicle :) ) go to autozone, and rent the brake piston tool, since when you return it they give you all your money back, and use that. It works so much better on calipers that are stuck or stiff than c-clamps.
Try this and if that doesn't work let us know and we'll go from there. Good luck.
