yikes, yea definitely looks like brakes are getting lower on the list of importance
I cant add anything to the stuck drum tho
We have a hammer at our shop just for this type of problem .. named Big Gibb (named from its owner who gave it to my father), its a 10 pound sledgehammer head on a 12 inch long handle for those tight area's that you cant use a normal sledgehammer if all else fails.. Gib will either loosen it up.. or break it off
