Ancient Chinese Secret: To knock the drum off, use a hammer. A BIG hammer. You won't hurt the drum, just wail on that sucka. Be careful not to hit the wheel studs though. If it doesn't come all the way off but just gets loose, your drum is dragging on the shoes. You can turn the drum counter-clockwise to try to "unscrew" the drum. If all else fails, you're going to just have to rip it off and plan on getting new shoes and hardware kit. If this happens, dont' forget to get the drum turned or you'll run into issues again the next time you pull it.
Any questions, lemme know. Ex-mechanic that'* dealt with a TON of f'n drum brakes. Discs are so much easier to work on...
