I’ve never played with a drum brake, but I’ve assumed that dust is ejected somehow in normal operation. The Continental design is sealed to contain the dust. Maybe dust in the drum isn’t a problem? Or maybe it’s designed so the dust accumulates somewhere other than on the friction surface inside the drum?
