I am getting ready to do a brake flush myself, on my G37 and I wanted to know if using a non-Infiniti brand brake fluid such as Super Racing Blue Racing Fluid is ok for the warranty?



Cheers!

What does the owners and Factory Service Manual say about the proper use of brake fluid?

DOT 4 is fine. Just one thing to note about the Super Blue, the dye is illegal for use in Florida. You won't get stopped for it, but you could be fined or ticketed for it if it comes down to that.

Non-Infiniti brand fluid is fine. There isn't such a thing anyway. The only Nissan-branded fluid is the one they "exclusively" make for the GT-R.

Thanks for the validation! I live far enough away from Florida!

i wouldn't do the blue stuff while under warranty, ate 200 is actually the same fluid but doesn't stain your lines blue if you want to use that stuff

i personally use motul but its about twice as expensive and not really needed unless you track the car. i just love the pedal feel it gives me though

Do you really think the blue dye will void the warranty? I like to swap between the Blue & Amber, so I know that got all the fluid out of the system...

i personally don't know how infiniti is about that stuff, but i just hate all that blue in there...its quite easy to figure out when you've gone through the whole fluid if you go through more than a half bottle of the ATE.

also, why do you need to do a full flush? i only ever did that on my race cars, it really doesn't matter on a street car.

If you're going to bleed it, why not do a full flush. You've already opened the bottle of brake fluid. It all mixes eventually after enough driving and braking. I really don't see bleeding it partially as very useful. ymmv

On that note, how many quart(s) are needed to flush out the system on a sedan with the bbk brakes? I mention sedan because coupe likely has shorter length lines.

I personally don't think so, but you never know with dealerships.

My biggest gripe with the blue fluid is that it does stain. At least it did on my Maxima. Which makes it a little trickier to see at a glance if your new amber fluid is still clear. Then again, a test strip can always be used.

With the Motive bleeder, i go through at least 1L and always try to do a full fluid replacement (or that 1L, whichever is less.) This equates to going around the car quite a number of times.

The only time i bleed a little here and there is if i suspect air in the lines.

Motive PowerBleeder FTW! It makes changing fluid/bleeding almost fun, and damn easy. I actually dont mind doing the recommended full replacement every year or two. Sometimes its a little bit of a pain to setup and get sealed to the master cylinder....Ive been considering making my own attachment using a spare master cylinder cap and a plastic barb fitting threaded/glued into the center of it.

As for fluid, look for Castrol LMA. AutoX-ing friend of mine swears by it, so for a daily driver it has to be just fine. Plus its clear so no dyes to worry about.

I'm using the super blue. It isn't necessary, but it makes it much easier to know when your lines are clear if you switch back and forth between red and blue.

I don't track, but I do drive spirited.

I use Castrol LMA in my 57 MGA since it does not contain silicone, but it definitely needs to be changed more often then ATE Super Blue Fluid. I did use the Motive PowerBleeder for about two years, but I always had issues with the seal and getting brake fluid everywhere. I ended up putting it on eBay and I switched to Mityvac Mv6835. Not trying to sound critical.

^ Wow, pretty penny. How's it working for you though? Curious, and it's always a good excuse for a new toy.

Thankfully i never had problems with the Motive. If i had to nit, it's that the cap is very tight to put on, which isn't necessarily a bad thing for sealing purposes.

oldschool33

The MV6835 works well, I put the compressor up to about 90lbs. and the job is pretty quick. Not much different than the Motive, but I get to use my compressor!

90psi? Isn't that a little too much pressure going through the lines? Or is it stepped down and regulated further down the system? (i.e. before it reaches the reservoir.)
