Electric Vehicle Brakes

[invader166]

I recently found out that a company in Canada called NRS, fabricates a set of specialty brake pads specifically for electric vehicles.

They claim that moisture buildup on regular brake pads can lead to premature brake failure. Their pads are made with a galvanized steel backing, featuring many, many hooks that physically connect the friction material to this backing plate as opposed to the material simply getting glued on.

I'm curious if there is any solid evidence to back-up this claim. In theory it seems plausible, but I want to see if anyone has ever actually encountered issues like this in all of their time of EV ownership.

Here is a very convincing demo for the use of the NRS brakepads from a YouTuber I like - Rich Rebuilds
Start watching the video at 11.39

I do have some doubts that Rich Rebuilds may only be doing this because he is sponsored by NRS however.

I have only changed the brakepads on 1 EV I have owned. An 8 year old Hyundai BlueON with 70,000km.
Am not sure it really needed it because it didn't look as bad as the ones in this video.
The mechanic suggested it because of the car's age and I didn't argue with what could be a safety issue.
After 5 years the Soul EV brakepads have not had a problem.

TeslaBjorn is now testing the NRS pads. Hopefully we'll get a follow-up video in 6 months time.

Another youtuber by the name of ChrisFix has posted about them too it seems. He visited their actual manufacturing plant.

He also posted a follow up video as well.

They may be a better product, but I wonder if they are necessary. If the story is that EV brake pads last longer because so much of their braking is regenerative, so the pads are too old to be safe - well, I have an old sports car which I use very little, so the pads don't get much wear. I think they are at least 25 years old, and they are doing fine.

Yours might be a bit of a special case, as I'm sure you probably store your sports car inside a garage somewhere, where it's protected from the elements.

If you don't, then I must say, I am truly impressed! Do you remember what brand they are? Do you have any photos of them?

 

[IanL]

Yes, I keep it garaged. I think the pads are branded Suzuki (as is the car). I don't have any photos to hand, but they don't look out of the ordinary.

YouTube reviewer TeslaBjorn added NRS - Electric Vehicle Brakes to his Tesla Model 3 last year.
Sometimes I doubt how independent these reviews of products are given that the reviewer is either being paid directly, or is getting the product for free.
Well here is a follow-up to that first video.

I have a pretty high degree of confidence in both Bjorn Nyland and Rich Rebuilds. If they both say they're good pads, then they're probably good pads. As to whether it's necessary or not, I agree that that's an entirely different question.

 

[JejuSoul]

Four years later and no one seems to have been convinced to buy these. I agree with the last comment. They're probably good pads but not necessary. Replacing with regular brake pads makes more sense given how little they are used.

There's a good comment on DIY replacement here. :- EPB tool for rear brake pad replacement

Indeed, a cure looking for a disease, though does seem superior. I've dealt with sticky calipers on older cars before, and it was always related to rusty pins, water in the brake fluid, or bent/missing pad guides (those tiny stainless steel 'clips'). Never had a pad pop apart, but have had drum brake shoes lose their lining due to rust bonding the friction material to the drum better than to the shoe.
