In Formula E, they mostly brake with regen so much so that they completely did away with rear brakes. Whether or not current road cars can do the same I do not know. But from what I have heard many electric cars have problems with their brakes because they are used soo infrequently.
They did away with rear hydraulics…for awhile. After testing incidents they added back in a one time use hydraulic emergency system for the rear.

Very interesting
Rears are often drums on modern EVs for this reason. Fronts are usually still disks because some people might want to do more spirited driving.
