Do Nismo calipers have two bleeders?

NissanParty

Ok, I feel like the dumbest guy in the world, I was reading about my brakes... I have replaced the fluid twice... and I saw talk of inner and outer bleeders. It is night time now so I am not going to go look, but do these cars have inside and outside bleeders on the calipers? I have a 2019 Nismo.

I have only been bleeding the outside bleeder. If they have two, I guess I need to bleed them again!!

Yes you have 2 bleeders on each caliper. To bleed, you have to do the inside one first. Then the outside one.

Yep, 2 bleeders circled in orange, from the last time I rebuilt them

I was just reading this, Step 11 states OUTER first, then inner.

If doing it with pumping the pedal. It works best going the inner one.

Dang!!! I guess I have to bleed again. What a bummer. But it will be nice to see all that old fluid coming out of the back bleeders that have never been bled.

Not to contradict you, just trying to learn, but why would it matter between power bleeding vs manual bleeding?

Also, the web does not have a definitive answer. By the sounds of things...it doesn't matter. I think it's debated more than "which oil should I use"

I've actually tried to picture the hydraulic circuit of our calipers in my head, trying to figure out why it matters. I/m not computing anything.

Willwood says outer then inner on manual method: https://shop.wilwood.com/blogs/news/...r-brake-system

again for reference, not trying to prove a point.

I've tried both methods. Did the outside one first, then the inside. Still got bubbles out of the outside one on the second bleeding. When I do the inside one first, and then the outside. I don't get any bubbles on the second bleeding.

I will try today as I'm doing a flush after tire replacement.

I used power bleeder. Switched between Inner and outer. Didn't see bubbles get induced into the other.

so, didn't make a difference.

Service manual doesn't say anything about inner or outer bleeders.
Just rear right, front left, rear left, front right, in that order.
