Lotta Brake Dust - R1S Quad

where is the blended brake setting?

In settings under driver assistance if I remember correctly.

if you use Driver+ it'll use the friction brake to slow the vehicle to maintain its distance to the car in front of you. if you have dynamic brake assist turned on, it will apply the friction brake if the system thinks you might potentially hit the car in front of you. and there's the regenerative brake assist feature that will use the fiction brake if regen is limited.

Where did you get this information? The truck definitely uses regen in all braking conditions and because of brake blending, your brake pedal will always move a little on its own any time brake lights are needed. It then supplements with more friction brake if faster deceleration is necessary. Not being a jerk, I genuinely want to know if my truck is braking differently in various [non emergency] situations.

As others have stated Rivian uses blended braking at low speeds all the time. You will notice this if you watch the brake pedal from the back seat.

If the regenerative braking assist is off (my setting) then it should not blend in brakes when Regen is limited.

My observations of driver plus is that it does use Regen however it uses friction brakes more in some situations because it doesn't slow down far enough ahead of time ...resulting in significant braking force being needed to slow the vehicle.

Something I suspected as the culprit is traction/stability control. Would explain why not everyone is seeing the accelerated wear on the pads.

Truck burns through brakes. They are sneakily using them and not letting us know. 60,000 miles. I've done front brakes once and back brakes twice.


Blah blah blah. Don't come at me with I'm doing something wrong. Truck applies them a lot.

Not comming at you but do just want to say I have 45k, always kept the blended brake thing off, and I do my own tire rotations and check my pads. Mine are essentially at new thickness....all around.

So maybe Rivian calls it normal.....and I have seen them call alot normal....where normal.....is some have issues and some don't.

What is your elevation change In a given day? My house is at 2300' on my 10 miles drive to work I drop to 800' and back up to 1700'. I live in the hills of western ny where every drive you probably lose or gain 1000'.

Highway driving is the same. Up and down? Is that your topography?

There are so many variables with a truck that brakes itself with out us running A to B tests what happens to yours or somebody else isn't the same as me. What about weather? Snow and salt? To many variables to compare but read through the 2 threads I posted and you will see a pattern of people who live in Hilly situation with 4 different seasons sure seem to be using there pads at a higher rate.

Maybe we are all just idiots with the brake pedal and can't read a screen that says blended brakes.

Hard to say....lots going on.

But I am in heavy salt Wisconsin, so I do worry a bit of how little my brakes are used, but so far so good. And I have not done any brake maintenance. 2 winters now. But I do wash it alot and it is garaged at night.

But very little hills.....we don't have many of those here.

I think this must be it.

I would turn off the blended braking function, so you know when the brakes are being applied. At the 7,500 inspection I had limited to no brake use. By the measurements given I should get 110k miles before brakes are needed.

53,500 miles 60% of original pads remain. I'm thinking 90K+ miles for me.

Considering my 6k+ lbs 2019 Audi Q7 w/ 83k+ miles on it has it's original pads & rotors, any less than 100k miles on my original R1S brakes/pads would be a disappointment considering that I ALWAYS are in max regen mode and rarely touch the brake pedal.

All vehicles of the last 20 years use brakes for traction and stability control. I had a buddy burn through his rear brake pads in 2k miles on his Porsche.

i was hoping an R1S Quad would not need to use brakes for stability since it has 4 independent motors.

Here is an interesting update. I was out running errands for a couple of hours. When I got home I measure the brake rotor temperature with my IR temp gun. The brake rotors were around 20F, same as the outside air temperature. I was driving manually without Driver+.
