You can tell if it is hanging on the brake shoes if it kind of springs back on you when you try to pry it off. If it is hanging on anything else it will come to a dead stop and not feel like it is trying to move back. Make sure the adjuster is all of the way in and try tapping the drum with a 2x4 or brass hammer to get the shoes to move in. Is this a truck that has been running or sitting? I also almost worked myself to death once on one that had been sitting up. I figured out that the parking brake cable was rusted stuck and the shoes weren't comming all the way in.
