There’s been a few suggestions that drum brakes should make a come back, for EVs.

They’re enclosed so they don’t get dirty, the inner face of drum will rust less than discs, fade is not an issue thanks to regen braking, and before they get too hot and fade drums will brake harder than disks (thanks to a higher pad surface area). And they’re enclosed so they also keep the brake dust inside the drum, making it easier to dispose of safely.

Drums are heavier tho.

Drum brakes are cheaper, too. The VW ID4 has rear drum brakes for all of these reasons and it seems to work out very well.
