I had the same problem when I changed out my brakes. All you needed to do to compress the rear caliper piston is to get a master cylinder kit. you can rent these at any autopart store. What the kit does is it pushes and twists the piston evenly which is what a c clamp does not do. Trust me...if it wasnt for the guys on this forum I would have done the same thing you did. Just for the future just rent the kit and twist the piston back in. A time saver!!
