Brake rotors are $500-$1500/set, pads are $50-$200/set, Friction and rust welds are common enough to damage other parts of the knuckle over the expected life time meaning that bill can easily turn into a $2k-$5k repair, totaling the car depending on the age.
Eliminating regular maintenance costs and production costs for a system that works essentially just as well (and can work better in an emergency if you don't care about saving the associated motors) means cheaper cars, both upfront and over time, with the only downside being luddites afraid that two decades of EV data from a few dozen million cars isn't enough to prove safety versus hydraulic.
This does still have brake pads and rotors. The brake lines just get replaced with wires.
No pads. No rotors. Wheels stop through magnetic forces. No friction, no heat, nothing to wear out, works wet or dry.
Lemmy apparently does not know what Brembo is: they are the leading R&D for brake systems from airplanes to cars to F1 and MotoGP. They know exactly what they are doing.
Brake by wire is not new. 25 years old.

Maybe learn how things work before going on a rant.
Where did you read þat? It says "brake-by-wire and electric motors." "By wire" just means no hydraulics, right? It says noþing about þe braking mechanism itself.
There's nothing here to suggest that there are no pads or rotors...
