Please educate me! And in the best case scenario where I will be driving the most conservatively, can I expect $150,000 miles out of them?

No expert on it myself... unless slow stop and go traffic where using mechanical brakes... in typical hybrid driving you'll use regenerative braking so less wear and tear on mechanical brakes..

When stopping if you can slow down gradually enough so that the Eco needle never bottoms out in the Charge section the van is just using the electric motor/generators to slow the van by charging the battery. If you brake hard enough to bottom out that needle the van is also using the standard friction brakes to slow down.

Wow, that's great information, thanks

Haha, and that's what I do most of the times, which means my brakes will last an awful long time

Oh, and if the battery is full you'll hear the engine rev when slowing down. The van is still using the motors to slow down but it is dumping the electricity into spinning the engine (with no fuel). You'll get this on long downhills as well when the battery fills up. Sounds weird but totally normal.

Ah, I see now. I always wondered what the hell that is

I was about to discuss that with my Dealership, I thought something wrong was with my transmission messing up the engine

Toyota is an amazing company, this is my first Toyota, and I'm sold. I can't wait when they make the first fully electric Sienna

If you really want to learn about the internals of the transmission

i is a great but long watch. TLDR eCVTs are NOT the CVTs or even transmissions most people are used to. They are super solid machines but behave very differently.

I wish there was a separate indicator that defines regen brakes vs standard (friction) brakes. "Bottoming out" means maximized regen AND/or various degrees of standard braking. The left dial seems to have a lot of space for more information like RPM, AMPs generated/lost, Traction battery voltage, battery temperature. Am i asking too much ?

I suggest servicing them at 100k regardless to keep the pins from sticking.

Why do you keep asking this question?

How long do hybrid brakes last?

I am at 80k miles and dealer says my brakes are still pretty good. Is it because I am super conservative driver, or hybrid brakes do last this long? Thanks

I realized that but it was too late then. Apologies. Moderators could merge the two threads. Thanks

When the needle bottoms out, does that mean it's still charging the battery, even if it's using the Friction Brakes?

Yes, it's just supplementing the regen braking with the friction brakes up to the point you lock them up (which may not be completely possible with anti-lock brakes) since at that point the wheels are no longer turning. But you are defeating the purpose if you routinely do this (Emergency braking aside).
