Brakes can get rusty if they don't get engaged frequently enough b/c you're using the regenerative braking most of the time. I've read that a lot of newer EV's will periodically engage traditional brakes to help alleviate this issue though.
FWIW I just had my 2018 leaf inspected and at 22K miles they said the brakes looked good.
- manmal 6y agoYes, that’s what I meant. For some reason my ICE’s brakes were so rusty after 5 years that they had to be replaced. VW uses drum brakes for that reason now, at least for the ID3. Those don’t really rust AFAIK.
- fred_is_fred 6y agoI thought drum brakes were considered inferior/cheap/old tech and that everyone switched to disc about 20 years ago? Edit - I should add that when buying a car in the early 2000s having disc was considered a nice feature like "rack and pinyon steering" which was frequently mentioned then too
- manmal 6y agoIndeed! But since EVs rarely need the posterior brakes (if at all), low maintenance becomes more important than performance. Changing 2 disc brakes costs ~€500, and I‘d rather not pay that every few years.
- fred_is_fred 6y agoI had a Neon in the late 1990s and it had disc front and drum rear brakes, I assumed it was just because it was a cheap car. That's super interesting how it just isn't as needed for EVs.
