I had a 5th gen Camaro that had terrible brakes because I could never get the rotors/pads hot enough during normal operation to properly "clean" them. They were so big you just couldn't do it without visiting the freeway or a race track. I had to get the rotors machined or replaced about once a year because the car mostly went to the grocery store.
I think the best thing you can do is to occasionally stand on the brakes as hard as you can from >60mph. In a heavy EV you probably only need to do this once a week/month.
There is something about mechanical contrivances and rare use. Complex machines tend to get sloppy when they aren't exercised regularly. The best way to prove a machine will work correctly is to use it frequently.

The best way to prove a machine will work correctly is to use it frequently. I see this a lot on other sites where people talk about buying an old Landrover or Range Rover as a "weekend car". That's never going to work. My nearly-30-year-old Range Rover had the fewest problems when I was putting around 3000 miles a month on it, all year round. If it sat long enough for the engine to cool to ambient, sure as shit you'd find something wrong the next time you started it.
- yabones 9mo agoStanding on the breaks frequently is how you end up with warped rotors, so there's some nuance here. Once in a while will stop rust and guck building up, frequently and you're replacing the discs early.
- greenavocado 9mo agoTightening lug nuts in a circular pattern instead of switching opposite sides is also a great way to warp rotors and I wager is probably more common than most think
- WarmWash 9mo agoIt's not the pattern that matters so much as the torque spec, but you should still optimally switch sides while using a torque wrench.
- greenavocado 9mo agoI maintain that its both
- clash 9mo agoThis appears to be even more of a problem with EVs and their regenerative breaking and I wonder whether this could not be easily fixed by software: "Breaks were not used recently or car did not move in some time? ⟹ Temporarily disable regenerative breaking for a few minutes until the break pads can be assumed to be clear again."
- SauciestGNU 9mo agoReminds me of the concept of the "Italian tune-up" where carbon fouling in exotic sports cars would be rectified through a spirited driving session to cook it off.
