I'm getting ready for my first track day with my N in a few weeks, so I was planning to flush out the factory brake fluid with some good DOT 4 beforehand. However, when I checked the owner's manual for the fluid capacity, I noticed that it lists DOT 4 as the recommended brake fluid. Does this car come from the factory with DOT 4 already in it? Impressive if so!

Yes and it's DOT4 LV. Although, I would still recommend swapping out for a better quality fluid if you're tracking. Not that there is an issue with the OEM fluid, but Motul/Redline are just higher quality and have higher dry/wet boiling points.

I ran OEM fluid for 3 track days and a couple of autocross events and had no issue. Just swapped out because I did the SS lines and figured it was time.

Good to know, thanks for the info! I'll probably do the same and hold off until I do a full upgrade with pads and lines then.

What are SS brake lines? are those braided?

Yes, but make sure they‘re real braided lines. These consist of Teflon or generic PTFE ( polytetrafluoroethylene) inner hose wrapped in a braid consisting of stainless steel wire.

Not all SS braided lines are the same. Some have internal rubber hoses, these are not real braided lines. With rubber internal lines, they functions just as the OEM hoses and provide no benefit.

Do I need a special brake sauce for SS braided lines or can i use an OE equivalent brake fluid?

 

[RedVN]

No and you can use an OEM fluid. However, I’d be utilizing as a minimum, DOT 4 or 5 Racing Brake Fluid.👍🇺🇸

I also noticed that Motul RBF 600 is an SAE J1703 whereas oem is 1704. Motul RBF 600 also doesn't mention that it's LV. Is this still the better choice?
