Philip,
I agree totaly with Tom. Once the line is loosened or the bleedscrew is
opened the brakes should release - regardless of the condition of the MC
or any other part of the system.
I'd say the calipers are sticking; remove them, clean them up and
install new kits in them...
If they are sticking now the problem usually gets worse.
