Yes, you are encouraged to slam on your brakes at least once a month to get the rust off. I live on the west coast (rain but low humidity and hardly any snow), so its less of an issue.

First read your owner's manual to see if it says anything about this.

My EV for example has a brake cleaning mode that turns off regeneration for approximately the next 10 times you use the brakes.

Using that is probably going to be safer than slamming on the brakes.

You'd think with all that electronics it would be smart enough to use real brakes every now and then. The plug in hybrid Prius runs the gas engine every 100 miles or so.

  • I don't think that is a good feel, you sort of get a feel for how fast you slow down with regenerative braking and throwing real brakes into the mix randomly sometimes would make for a horrible driving experience.

    Better to have a reminder, surely the car could figure that one out.

  • Some cars do this. Audi and Porsche (if I recall correctly) use the disc brakes for the first couple stops each drive to knock off the rust if there's any build up. I think I remember reading that Ford uses the real brakes if you're under 5mph. I'm sure other manufacturers do something similar (other than Tesla which apparently doesn't do anything to help).
