Default disc brake piston won't retract

I put the TSM rear disc brake conversion on a '74 scout II. The directions said to take the calipers off the bracket to bleed them, so I did. After bleeding, one side was fine but the piston on the other side was pretty far out. When I tried to retract it turning clockwise with a needlenose pliers, it came out farther instead of retracting. Rented the piston retraction tool from AZ and even using that I can't get the piston to turn and retract. What can I do? Did I do something wrong or is the caliper bad?
