The easiest way to remove the drum is to remove it with the hub-brake drum assembly, and then you can use a hammer to separate the hub from the drum. This way you can also repack your rear wheel bearings. If you only want to remove the drum, then you have to hit it with a hammer to free the drum from the hub. Some times it also helps to back off the automatic adjuster screw from the rear of the brake backing plate.
