For those of you still on SRF, Motul or (shudder) ATE.

Thanks for sharing! I'm planning on flushing my fluid soon I'm still on OEM fluid. I bought a few bottles of the Motul RB600

Awesome read and find! I run rbf600 and always wondered why the pedal felt so mushy. Will switch to endless on next flush.

Interesting. I've been running ATE for seven years now without issue. I guess I'm just not on the brakes that much.

How is this in any way a test? For some of the fluids it simply notes they are using the fluid in some dude's car

Nice find.
It lays out all of the key specifications across the different brake fluids in an organized easy to interpret fashion.

I may try endless next, I noticed some spongy brake pedal feel during my first session with PFC bbk and SRF. However, subsequent sessions the pedal was back to normal. weird.

Try Endless and you will know what you've been missing. I first used ATE Super Blue in 1998 in my Golf3 GTI-VR6. Used it up until 2005 in my cars. Then tried Motul RBF660 for a few years. That was much better than ATE. My last two cars have been on Endless RF650 and it's by far the best fluid I've ever used.

Which is what, exactly?



I'm open to trying alternatives, just not sure how greener the grass actually is.

First of all, pedal feel is greatly improved. Like night and day difference. Brake fade resistance is also greatly improved. I've boiled both Super Blue and Motul 660 at track, but never the Endless fluid. But the single biggest difference for Endless is the nice firm pedal it provides. It's something you appreciate every time you use the brake pedal.

Tough choices. If your M was mostly a daily driver but were doing two or three open track sessions a year on a track notoriously hard on brakes what level of brake fluid is best? On OEM pads currently but purchased some PFC08's to try on stock rotors next time out. Currently flushing fluid once a year.

IMHO brake fluid is cheap enough that you should get the best out there. There are no negatives to a better fluid, other than price. It's not like track pads which may score brake discs. I daily my M3 and I run Endless fluid with no problems.

I noticed this too. I never had any issues on track with feel or modulation so I just ignore it now.

I have Torque 700 in the E46M3 and it has a very firm pedal feel. I've heard really good things about the Endless fluid too. Might give that a go for giggles...

I noticed Prospeed RS683 wasn't included in that list.

I'm checking out the Endless website now. They also have an S-FOUR product. Anyone tried this?

Wish I had found this post before I did my brake fluid flush last week lol Quality information, and I even discovered a new brand which I was unaware of (Torque).

After 2-3 track days I'll flush again and try out either Endless or Torque. They aren't anywhere near as expensive as the article makes them out to be too.

Endless on Amazon.com = $50.00

Torque from either ECS Tuning/Evasive Motorsports = $33.95

Look forward to see how the 2 compare to ATE 200.

so Endless is supposedly better (article and OP) but it has a wet boiling point 15 points lower than SRF.

So does that mean, you have great pedal feel until you boil your fluid - which leads to shitty pedal feel - while on the SRF you haven't boiled nothing yet?

I don't get it.

I always though to look at wet boiling point to get heat performance.

If you're driving to the limit of your fluid's temperature capabilities, pedal feel isn't your main problem.
