On both my Volvo PHEVs I often look at the brake discs and find them rusty from the amount of regen braking. it almost completely eliminates conventional braking unless it's for collision avoidance.


My EV turns regenerative braking off for the first use of brakes after beginning a journey, to avoid the rusting disc syndrome.


What car brand is it? I've read that Audi and Porsche do that.

Also is it only pedal braking? Or does it "fake" things out if you use one-pedal driving?


Brake rotors will noticeably rust overnight if left in wet conditions.


So your primary and emergency brake system elements are rusty and that is now somehow a good thing?
