I had a problem like this once on an old truck that sat for a while. The parking brake was released but for whatever reason it seemed like the pads were still sticking to the drums....maybe from rust? Anyway, I just gave it hell and all of a sudden I heard a pop and it started moving freely again. I'm assuming that the pop was the pads breaking free. With another truck, I had a problem with so much grease and dirt caked on everything that it added up to too much for me to push on my own. Good luck!
