Disc Brake piston stuck

I accidentally pulled on the brake when the calipers were off the rotor. I had to take the pads off and squeeze the piston back with a C clamp. Now, when I reassembled it, the piston won't move.

Any ideas?

I disconnected the hose and put more fluid in the reservoir, and it squirted out when I squeezed the lever. So I know that at least it's pumping fluid thru the hose. When I connect the hose to the caliper, the lever doesn't build up any resistance. ???

The piston probably got all cock eyed in the bore. Best I can tell you is to remove the piston, LIGHTLY hone the caliper bore and put the piston back in using new seals.

Yep. Time to get out that ole honing tool you've been wanting to use.
