Good day and thank you for inquiring with JustAnswer, my name is XXXXX XXXXX i will be the technician assisting you today. To get the caliper piston to retract, a caliper piston tool will be required to spin the pistons in, they do not push in but screw in as they are threaded for parking brake use. You can get this tool at most autoparts stores and should cost no more than $60, some stores, like Autozone have a tool lend service that you might be able to benefit from as well. I have the snap-on Blue point kit, part number YA8610A, if that might be of any use to you. I would suggest calling your local Autozone if there is one around and ask if they lend that tool as well. With the tool you will turn the piston as the backingplate of the tool applies pressure and that spins the caliper in

I have discovered the solution while waiting for your responce. To free the piston to rotate you must first remove the park brake cable and bellcrank (lever) from the top of the caliper. Once removed, rotate the park brake shaft counter clockwise about 1/8 turn untill you feel a detent. This is what releases a lock or ratcheting device that prevents the piston from screwing in.
