    Counterpoint: why would you need to replace brake pads on an electric car? Regenerative braking should rarely need the mechanical brakes at all.

      Regen has a limit to how much stopping power it can provide, some people drive with a lead foot, and even if you’re really good about it ‘rarely’ is not ‘never’. You will eventually need to change your brakes.

      Even if I wouldn’t need to, I would still want the freedom to change the brake pads myself if I wanted to.

      My Bolt EUV doesn’t hold itself on a hill as well as mechanical brakes. That and having a redundant system on board is usually never seen as a bad thing.

          Yeah, that’s kind of my joke when I describe driving it to my gas car friends. Still want them on my cars though for emergency quick stops. Met a deer on a blind hill earlier this year and had to come to a stop in a short distance. Otherwise yeah, regen braking for everything else and test the mechanical brakes once per trip to ensure they work.

      Regenerative braking does not work well in all scenarios, like heavy braking in an emergency or coming to a complete stop from a slow roll.

      Or five full track days in a heavy EV, I can say from experience that that will wear out brake pads pretty damn quick (Taycan 4S wagon)

      Also, torque vectoring will use friction brakes

        You are right for hard or emergency braking, but Hyundai’s regenerative braking at max is intended to be one pedal driving, and it easily stops you completely in a fairly short distance. I guess that isn’t the way others are doing it. I can get away with only using the brakes at the first stop sign near my house when I leave with a full charge, as the regenerative brakes don’t work when it can’t charge the battery. But I am sure I will still have to change the brake pads eventually anyway, which I would normally do myself during a seasonal tire changeover, so this news sucks.

          Oh yeah, you’re right. We had a BMW i3 for a long time and it also had good one pedal driving. I managed to forget about that since the Taycan doesn’t have one pedal driving basically at all

      Eventually, you do need to.

      My electric car (from 2014) has other stupid features, but at least, no electric parking brake. Rear pads were obviously very thin by now, and most likely the previous owner also changed them once. So I went to a self-service workshop last spring, brought along spare parts from a shop across the road, replaced them.

      Annoying part: drums came off relatively poorly, the new pad set needed treatment with a disc grinder (allegedly compatible part, but a tiny bit of metal was 2 mm too long).

      When the time comes and my factory made car wears down, I intend to build another DIY e-car, as I’ve done twice before.

      Except if you live somewhere with salt/high humidity, the rotors will get rusted to hell without regular use that gets them hot enough to boil off the water.

      I’m 50k km in, and my pads were at 85% when I asked them to check when getting an air filter replaced. I just wanted to have an idea of how they were wearing.
