Just wondering if anyone else is seeing such minimal disc wear. I noticed that my front discs were also beginning to corrode so switched off all regen and have driven for a week, coupled with some heavy braking. Hopefully they will soon clear up. The brakes are still excellent.

These look an awful lot like the discs on my Volt. No matter how hard I try, I find them very hard to clean with normal use. There are some who recommend driving with the parking brake engaged, but that sounds abusive to me.

I chalk this up as once of the quirks of EV ownership. I wish companies would build in a more useful 'brake-cleaning' cycle. The Volt will use the friction brakes the first time you touch the pedal upon setting off, but after that it's regen. This barely does anything as far as I can tell, as usually when leaving my neighborhood I hardly have to touch the pedal very hard. I feel like a brake-maintenance cycle should be 1-5 miles every 10th time, or something. Perhaps that would extend disc life more appreciably?

Thanks all for the advice. I have been wondering about the regen as it does regen on the dash even with the setting the pedal to off.

OK, so the of rolling and braking in neutral is good, I will try that in a safe place!

I use hyde's serum rust stopper after a weekly cleaning. Spray some on the disk while it's still wet and it reduces the formation of rust. It's designed specifically for this task.

Other than appearance it's hard to understand how this is any benefit. Anytime you hit the brakes with any force the rust will be gone instantly.

That's all its for, I don't like rust on my disks. I'm hoping that with one pedal driving, I can basically never touch the physical disks (unless I find myself on a nice bendy road).

My passat gte had one pedal mode and corrosion got so bad, it gouged tracks in the disks making them unsafe. VW refused to replace them under warranty so I had to do it myself.

I believe earlier on they did have an auto brake cleaning feature that involved using the friction breaks during some elements of driving about. But it was identified as one of the potential sources of reduced efficiency/range so that, after all the whining we did here about range, it was nixed or made much less frequent in a later update.

What I'm saying is, as one of the earliest adopters, @Arjo , you only have yourself to blame :)

Haha, I accept fault 😂

My brakes drag when I first back out of my garage. If I haven't driven for a couple of days you can really hear them scrubbing for about 20m or so then they release. I'm not having any trouble with rust to this point.

Edit: I don't use OPD so I do engage the brake pedal pretty regularly and I'm sure I occasionally get into friction braking.
