line lock not releasing?

so i installed my line lock today
cut the existing brake line, used flare nuts to mate the line into the lock, pretty straight forwards

as i was driving though, i noticed the brake pedal would get harder and harder, and something is preventing the fluid from returning to the master cylinder

i checked to make sure it was installed in the right direction (decided to put them on the front brakes after all)

i swapped polarities on the wires (even though they said polarity doesnt matter)

now, did i just get a bad solenoid?

i can feel the difference in brake pedal with it on or of BUT with it off, there is still too much restriction to allow the wheels to spin freely and i can feel the brakes dragging...and smell it too
