Most drum brakes have an adjustment which can be accessed by removing a rubber plug. You loosen up the brakes so one can pull the drum. Personally I thought the back brakes on my Focus are the worst brake design I've ever seen. I replaced the brake pads because the rear one on the drum was only a couple mills thick... the new ones were the same thickness. Cheap.
I'm with ZTWsquared, replace with discs... except kits are more expensive then the cars that need them.
