Electric vehicles are heavier, which means they must spend more brake pads to stop. But they also use regenerative breaking, which reduces pad wear. So I'm not sure if they make it worse or not.
- gr2m 3y agoI drive an EV for over a year, I barely use the break any more. Single pedal driving is wonderful
- qwertox 3y agoCurious: How do you roll towards a red traffic light, do you somehow push a "neutral" button?
- jordanbeiber 3y agoJust take the foot off the accelerator gradually. The kia I drive still roll at a couple of km/h when accelerator is fully released and will not hit 0 unless you use a paddle by the steering wheel (or use the breaks).
- IncreasePosts 3y agoYou just slowly let off the pedal as you approach.
- dzhiurgis 3y agoRelease the pedal. Car figures out where the next car or stop line is (I think. Even when you're not using radar cruise control).
- cbolton 3y agoI hope we'll crack down on heavy SUVs vs normal cars before electric vs ICE.
- ok_dad 3y agoTires are somewhere near the top for distributing microplastics and heavier cars cause more tire wear, so yea we should get on that. I live next to a main road and we run filters in our house and have to wash the surfaces at least once a week to get off the oil and rubber dust. You can't just dust that stuff either, you have to wash it with soap. I almost regret buying this place, but where else would I have bought in this economy!?
- darrenkopp 3y agoThey likely make it better. I rarely use my brakes unless I have to brake suddenly.
- realusername 3y agoThe danger with electric vehicles is actually that the break pad is in risk of rusting since you don't use it enough
- mschuster91 3y agoHit the brakes softly once after driving and the rust is gone.
- dzhiurgis 3y agoThat's why some EVs are moving back to drum brakes
- kube-system 3y agoThe same thing happens to ICE vehicles while parked. It usually isn't a big deal because the area most prone to rust is the rotor surface. And modern brake pads don't usually have any issues rubbing surface rust away very quickly. e.g.: https://cimg0.ibsrv.net/gimg/www.corvetteforum.com-vbulletin/1234x676/rotor_rust_340b7490ea6f881c4ad0de5f3df46744435588c4.jpg https://cimg0.ibsrv.net/gimg/www.corvetteforum.com-vbulletin...
- _whiteCaps_ 3y agoI have a Bolt and the brake pads rarely get used. It's almost all regenerative braking, I would bet it's much better than ICE cars. Tire wear on the other hand... :(
- zyang 3y agoI love the little hand flap that does max regen. Bolt could be a cult classic too bad GM was in such hurry to kill it.
- nozzlegear 3y agoThey’ve unkilled it last I heard. I got an email a few months ago from Chevrolet saying they decided to keep making Bolts due to their popularity, and to keep an eye out for the next model in 2024 or 2025 (can’t remember which year).
- nozzlegear 3y agoSame here with my Bolt EUV. The only time I use the brakes are when I occasionally misjudge how quickly I’m coming up on a turn and one-pedal braking isn’t slowing me down fast enough; or when I first leave home, the car is fully charged, and one-pedal braking can’t regenerate the battery any further so it won’t brake for me.
- cjensen 3y agoPad wear is the source of the pollution. If there is less wear there is less brake dust pollution.
- jordanbeiber 3y agoBut you rarely have to brake an EV though. I’ve had two EV’s over the last 6 years, and I have to remember to occasionally hit the brakes to keep them from rusting. One pedal driving is just money - saves power and is just much smoother over all than old school breaking. IMO.
- EForEndeavour 3y agoI've never driven an EV. How do you approach stop signs and red lights other than braking? Is "engine braking" (regenerative braking?) strong enough to handle that big a fraction of slowing down in city traffic?
- thejazzman 3y agoIt's a timing skill you rapidly develop. Switching models throws off your timing, so don't be surprised when you initially use the brakes more.
- bryanlarsen 3y agoThe engine can slow down the vehicle at roughly the same rate it can accelerate it. And if you have an EV that has a 3 second 0-60...

- WaxProlix 3y agoGenerally, yes. Usually there are settings for how much regen you want, but the term 1 pedal usually inies a regenerative brake strong enough to stop at stop signs or when exiting freeways.
- kube-system 3y ago"1 pedal" just refers to vehicles that perform a high degree of regen when the throttle is lifted. Other designs that require the user to press the brake pedal are not necessarily engaging the brake pads when you do so, many of them are also slowing the vehicle with regen when you press the brake pedal. When you press the brakes on an EVs or hybrid, they typically use regenerative braking up to the limits of the motor and charging system, and only apply the brake pads after those technical limits are met. There are many "two pedal" vehicles that can come to a complete stop, or close to it, with regen.
- kalaksi 3y agoBut gasoline also needs ongoing heavy transportation over long distances
- deleted 3y ago[deleted]
- IncreasePosts 3y agoTire wear and tear, which can also give off nasty particles, is also increased with the generally increased weight of EVs
- dzhiurgis 3y ago30% higher tyre wear vs 90% less brake wear && 100% less cancer fumes
- IncreasePosts 3y agoNot 100%, because there are nasty emissions associated with the generation of your electricity however you charge. For the record I have an EV(model Y) and drive that preferably over my other cars.
- techdmn 3y agoI drive a Tesla Model 3, a few thoughts: * I'm hard on brakes in general, but have over 70k miles on the original pads. Regen braking reduces brake use a LOT. * Regen does NOT bring the car to a complete stop, the brakes are blended in below something like 5 MPH. The rotors are not going to rust away, they see action every time you drive. (Some surface rust is fine and normal, EV or no.) * EVs can be heavier than ICE cars, and most are. There are many things I dislike about Tesla, but the Model 3 is a feather weight in the category. A comparison I like to make is to the AWS Dodge Charger, which is heavier by a couple hundred pounds. I won't even talk about trucks and SUVs.
- thejazzman 3y agoIt DOES bring them to a stop in newer models. Not sure which year it started but it's been at least 2 But I know what you mean from my older models
- actinium226 3y agoAre you talking about the hold mode they introduced a couple years back? It will bring the car to a stop but (as compared to the previous mode where you had to press the break yourself below ~4-5 mph), but I'll be good money it's using the brakes to do so. Particularly when it's activated on an incline.
- jader201 3y agoI drive an EV6, and I’m almost confident it uses (or can use) regenerative braking to come to a complete stop. If I use the ePedal or the brake paddle, the stop is super gradual and you never feel the “grab” that you feel when using the brake. Also, I can sometimes feel/see it slightly rolling (so it’s not even truly a complete stop). I’ve seen some people swear that the EV6 always uses friction braking at stops, but again, I’m pretty sure this just isn’t true.
- imp0cat 3y agoIt's probably using mechanical brakes just to anchor itself while stopped (automatic parking brake).
- Lendal 3y agoGood to see dozens of replies to this. Means EVs are popular. Anyway, they're right. Brakes on EVs are normally just for emergency use. Regenerative braking (lifting up on the accelerator pedal) is all you need about 98% of the time. Traffic lights, stop signs, parking, and other such planned stops are all handled by releasing the accelerator which brings the car to a gentle stop while feeding the kinetic energy back into the battery. That's what they mean by "regenerative braking".
- l1tany11 3y agoRegen braking in most EVs is significant enough that the brake lights come on when you lift off the throttle pedal (which is what engages the regen). Tesla has said their brake pads are potentially lifetime. And for good reason. You barely use them; so much less than a normal car it’s not even close. I have a friend with a 3 approaching 100k miles and isn’t even through half a set of pads. My EV, you couldn’t even bother me to check. I already know it’s pointless. There is a lot of variance EV to EV. Some have strong regen, some not so much. Some use 1 pedal driving, some don’t. For instance the Porsche taycan brake pedal is setup such that the first part of the travel uses exclusively regen braking, and as you push harder it blends in more and more friction braking too. Don’t expect this to become common though, as this primarily just benefits real performance driving. Trail braking is very hard/frustrating without this kind of feature, but driving that way on the street is certainly dumb, and probably illegal (could fall under exhibition of speed?).

- maigret 3y agoThey make it better. One data point is that VW had to install drum brakes at the rear as they get barely any use. https://topgear-autoguide.com/category/tech-future/vw-electric-car-why-the-id3-drum-brake-makes-sense1607847651 https://topgear-autoguide.com/category/tech-future/vw-electr...
- byw 3y agoI wonder for drivers who drove with regen-only for too long, do they lose the reflex to hit the brake?
- recursive 3y agoNo. I do fine when I end up in a rental ICE. In my EV, I still use the brake when I need more stopping. If I zone out and forget I don't have regen, at some point, I'll notice I'm not slowing enough, and hit the brake, just like I would normally.
- jillesvangurp 3y agoEVs indeed have regenerative braking. Which means they use their actual brakes so infrequently that they commonly need to be replaced because of corrosion issues on some models. If you use your brakes, the corrosion comes off in the form of brake dust. When you don't use them, it builds up and reduces the effectiveness of the brakes to the point where it becomes a safety risk.
