I seem to recall a looooong time ago that someone had a machine that could surface the drum shoe arc to fit the diameter of the drum. But I haven't seen or heard of anyone doing that in recent memory. Perhaps an old timer or old school shop may still have that capability. The practice could have been discontinued due to the dust it created, even after they quit using asbestos. (At least I think they use to.)

On a side note.....the converter is a factor in how high one can go before the brakes can't hold it. One can usually bring the rpm's higher with a looser converter.
