One point about drum brakes not mentioned by anyone so far is that, at least in the old days, the shoes were "arced", i.e., lining material was removed by a specialized machine to match the ID radius of the wheel drum. This is particularly important if the drum and has been "turned", i.e., the ID radius is larger than OEM. The purpose of this procedure is to assure uniform contact between the shoe lining and the drum inner surface. If this procedure is NOT done, then brake efficiency WILL suffer if the two radii are different.
