rear brake drum froze

[rustbucket]

I can't get the left rear brake drum off. The trucks been setting up for 17 years. I can turn the drum backward by hand but its froze solid when I try to turn it forward.
The parking brake handle doesn't indicate it's set..but, then...I know that doesn't mean anything.

Suggestions...?

Is it in gear ?

brakes are made to work better in forward than reverse, so the forward rotation may be causing them to set. Try a little heat or spraying WD 40 in there and letting it set for a while. JUST BE CAREFUL IF YOU USE HEAT AFTER USING THE WD 40, IT WILL BURN. Gently tapping with a hammer will help sometimes.
