Honda Accord Caliper wont reset!

Honda Accord, 2002, 94,000 miles. I was changing the rear disc brake pads and everything was going along just fine until it was time to use the c-clamp. The plunger simply would not budge. After this I released the bleed line, and the main line going into the caliper and still, nothing. I was wondering is there some special technique that I dont know about for changing honda brakes? Thanks for your time.
