Who can answer my car brakes repair dilemma?

I can't identify the problem with the adjustor screw at minimum, but I would worry enough to bite the bullet and get professional help. If they are rubbing, they could generate enough heat to damage either drums or bearings.

Is there any possible way there could be parking brake cable tension that's only affecting one side. Or possibly something is preventing the wheel cylinder from retracting after being applied. These are just improbable guesses, but I don't think I've heard of the situation before.
