What is Audi A7’s Brake-by-wire system?

I have heard about brake-by-wire system in the Audi A7 and I am curious to know what it is and how it works. Can someone please explain? Thanks!

The brake-by-wire system in the Audi A7 is a modern technology that replaces traditional brake systems with an electronic system. Instead of using physical components like brake pads and calipers, it uses electric motors to control the brake system. This results in smoother and more precise braking.

One of the biggest advantages of the Audi A7's brake-by-wire system is its improved braking performance. As the system is electronically controlled, it can respond much faster to the driver's inputs, resulting in better stopping power and shorter braking distances.
