Brake by wire means standard brakes, but the control mechanism is electronic, not hydraulic.
Still is a mechanical brake, just controlled with wires.
Overall, it should be less complex/more modular than hydraulic systems that have to be integrated with the drive train. (But it also means more ‘opportunity’ for embedded sensors and non-user serviceable parts signed by code, so who knows how they’re going to mess it up.)
