You may need to remove assembly clips that will be on three lug bolts if you have never had the drums off before. Don't worry about destroying them because you don't need them they are from the assembly plant. You may also need to loosen the tensioner accessable through a port with a removable rubber seal at back top of mounting plate. The tensioner screw has a star wheel you can turn with a screwdriver. Hitting the outside of the drum with a hammer will help loosen it up. With the drum off clean it and the brake parts with brake cleaner and clean rags.
