Take the drum off and check the thickness on the shoes. Sometimes the drum might be stuck on there because of a rust ring on the edge of the drum caused by the shoes not contacting that area of the drum. If you have a plug in the back of the backing plate then loosen the star wheel, but if not then get a couple of screwdrivers of a BFH and go to work but try not tho damage the drum. Then once you get it off compare the thickness of the braking material on the shoe to the thickness of the plate that the material is rivited to. (kinda lost of words but you get the picture) if you have more brake material left than the backing thickness then your good but if the backing is thicker than the material then you need some work done. Hope that helped but i 18 and still going through school so there is probably some other ways that might be easyer but thats how i have been doing it so far.
