If the parking brake cable is attached to the caliper, then that means that you will have to rotate the caliper piston in order to release it back to the piston bore.
They usually rotate clockwise, I have a special tool for this, because it can take a lot of force to get the piston going, but I have improvised on some occasions with success.
