Unless the conversion from speed to electricity is more efficient than to heat, shouldn't the degradation rate be the same? Or is the heat causing most of the degrading?



Braking force in EV is from magnetic fields in the engine pushing electricity back into the battery. Magnets and copper wires do not degrade when used. Pad brakes in EVs are only used when braking HARD, as in emergency stop. They degrade less because they are not used much.
