Did you ever get into a Bendix Automatic? I had those as a kid in the late '50s. Pretty amazing thing and a terrific brake with its three large shoes but I never found a grease exactly like the factory grease. It looked like white soap but was soft and not 'stringy' at all. I used one again years later in the '80s and learned that you don't use a Teflon grease in a CB hub! That really should have been obvious.
BTW, I think on the OP brake hub the problem is wear resulting from lubrication failure. The wear will be manifest in the drum/hub braking surface and the shoes. If new shoes don't make it good enough the brake sector of the hub might be a write-off.
