Electric vehicles should actually ditch disk brakes and return to drum. Disk brakes are great for heat dissipation (not a problem on EVs because regen is the primary braking system) but they corrode and rust if not used regularly (as happens on EVs). Drum brakes, on the other hand, can be basically maintenance free until you wear out the shoes and are fully sealed. Lots of trailers have 20 year old drum brakes that still work!
