Brake pad wear?

[Florida Panhandler]

Might be a dumb question but can you simply use old school brake pad retractors on the Rivian?

Hopefully they open up the OBD to 3rd parties at least enough to retract pads. I have two scanners that can do this on the later model BMWs, I'd like to see Rivian added to the list. But it should be years before I need that.

I decided to check online for Rivian brake pads. Rock Auto and Autozone allow a Rivian search but don't have anything, NAPA does not even allow searching on Rivian, and Advance Auto Parts came up with this.

Yikes...... hopefully just a placeholder image?

I did exactly that on my i3 when I got it. Rivian? ..... who knows till someone tries it, but it's pointless till we even have an option to purchase the pads & rotors.

For reference.... Rivian told an owner to make a Service Center appointment to change a fuse!

Morning - I have 27K miles on my R1T since mid May of last year. Brought it in for service last week and was told that my brake pads were at 4 and 5mm respectively and needed replacement. Has anyone else had issues like this? I have towed a 16 x 10' trailer for about 3K of the 27K miles but to be honest my main concern with brake pads was that they would rust from lack of use.

At 26,000 I was told my rear pads were shot and had them send me photos and i couldn't believe it but they were.

I was actually kind of upset because just like everybody who is commenting on this i almost never touch my brakes other than the times the regen system over heats and i have too. I have towed less than 500 miles as well.

After a long back and forth about what to do they covered the labor and i just paid for pads on the rear.

I was also told that it was a good idea to do a couple hard brake stops a week to keep everything moving well in there. I informed them that if that was the the best practice that they might want to let that information out to the consumer.

Edit
Pads were $129.08 with tax. Part# PT00122384-A

So as all of us rarely ever touch the brakes, how can the copious brake pad dust on yellow calipers be explained? Also, my rotors are always shiny, never surface rust associated with no use like on other cars. I suspect regen uses some sort of percentage of the regular hydrologic brake system

i also noticed brake pad dust which seemed odd since i have regen on high and have physically pressed the brake 2 times in the 2 months ive owned the truck. never towed.

is it possible Rivian regen uses the calipers to help stop more than we think or expected with regin braking? i assumed they just kicked in when youre near zero mph to hold the vehicle but not sure what else could explain the brake pad dust.

someone with a gopro needs to point it at the calipers and drive around to see whats happening.

I don't have my Rivian yet, but am quite interested in this discussion. Replacing the pads on an EV with regen at 25k miles seems odd; at 9,000 miles it seems incomprehensible. If this is a widespread issue, the posters above may well be on to something. Why a design feature that extensively exercises the hydraulic brake system would be incorporated is more than bit perplexing.

Just had a chat with the technician here in Chelsea, MA. They have seen three examples of this in New England and have elevated this for further inquiry. The working theory is that the climate in New England (wet and cold) creates rust on the pads. (I think this is a known EV issue friends in Norway had to change rotors because they were rusted ). The difference with Tesla is the hold feature that actually holds the Rivian whereas Teslas will "creep". That is the story and it makes sense. My technician said Rivian is looking into what this will mean for warranty etc. As mentioned early they took the labor off immediately. Should have my truck back in an hour or two.

This explanation still makes no sense. I almost never used the brakes in my MINI and it didn't have a hold function or creep mode. Brakes still looked new when I sold it at almost 14k miles and that was even after autocrossing it for probably 10 events using a lot of the brakes.

I was told the same thing ( western NY) snow and salt blah blah blah. My brakes were sticking badly for months that every time i moved i got the large pop*.

what does rust have to do with your original post that it needed to be replaced already? did the rust contribute to the wear?

 

[kurtlikevonnegut]

This seems relatively isolated with only a few examples but this actually seems like it could be a significant issue. If the truck is blending in a noticeable amount of mechanical brakes with Regen to the extent that it causes them to need to be replaced at 25k miles, that's a significant cost of ownership burden to add to a new set of tires every year @ $1600 per set.

I find it hard to believe that corrosion would cause millimeters of brake pad to evaporate in a year's time.

The hydraulic brakes have to be in more use than we think they are even when we hardly ever touch the brake pedal....

 

[Electrified Outdoors]

Something isn't right. My wife an an ICE Honda Pilot SUV and the original brakes are still on that at 50k miles. If the pads are gone at 27k there is a problem. Any pulling or other odd handling issues with the truck?

 

[pasdechevre]

@dleewla according to the tech they are looking at why the pads wear out too fast and one theory they are working on is that with rust on the pads when the truck is held in place, when stopped, this creates excessive wear on the pads . I have not had any issues whatsoever with brakes etc. during my now 12 months with the truck.
