I agree with Bob.
The return hole in the master cylinder is likely blocked.
Also, I'd suggest removing the caliper all together from the line (you may need to use a soft clamp to avoid loosing fluid) and using a vice to hold it in place, pull the pistons all the way out.
Often they can get a build up of corrosion, or a seal on the caliper comes apart and sticks the brakes on a bit.
A good clen with emery paper, or a new piston, and possibly a new seal could fix the problem.
Definately remove the master cylinder and clean the ports out too though.
Best to eliminate all possibilities.
