Brake fade happens at the pads, it doesn't have to simulate it.

How does brake by wire simulate brake fade?
Did you mean to ask: "Does brake-by-wire compensate for brake fade, and if so how"?

In a non-brake-by-wire car, if you get brake fade from overheated brake fluid, you'd know it not just by the fact that you ain't slowing down but also be pedal feel. As everyone knows, the pedal would go soft.
So, how does a brake-by-wire car simulate that pedal feel?

I'd guess a big red light flashes on the dashboard saying 'get your brakes serviced'. The EEC will detect that the transfer function of brake pedal travel vs longitudinal acceleration is wrong. It'll just run the pump longer for the brake stop, that's how pressure works.
