Another thing you might try first is disconnect the line at the slave and see if working the peddle moves any fluid. If you get fluid remove the bleed screw completely and see what happens, but I bet Kirby diagnosis is right.

Once I had it pushing brake fluid through to the can, I put it back on the car and everything was fine.
