The caliper piston should retract the same as most others. You can open the bleeder valve and try it that way. If it compresses easily, i'd start looking at the brake hose for blockage. If it doesn't compress, sounds like a frozen caliper piston. A c-clamp is ok to use. Don't forget to place the old brake pad between the c-clamp and the piston.
