Best Brake Fluid
Just did my first HPDE, (Hot Atlanta). Great experience. Great instructor, David Leonard. Time to replace pads and change brake fluid from stock. Just curious as to what you seasoned veterans consider to be the best brake fluid.

The best brake fluid is fresh brake fluid.
You'll hear a lot of votes for SRF which I'm sure is great stuff, it's also insanely expensive. I've always used Motul 600RBF with great success.

Motul 600 is a very good brake fluid. However, Castrol SRF is the best. Of course it does cost more. Motul is about $18 for a 1/2 litre bottle, Castrol is about $73 for a full litre.
A freind of mine was always singing the praises of Castrol, saying he would change his fluid at the beginning of the year and would never bleed his brakes all year. I of course, would never want to buy that $73 bottle and would run Motul, bleeding after each session. When we completed the new car this winter I thought I would try this Castrol stuff and see for myself. Sure enough, I haven't bled my brakes once all year. So which one is really cheaper? Not only does it end up being cheaper, I have eliminated another of the jobs I have to do at the track. The longer I do this, the more I am looking for ways to cut down on maitanence.
I have both Motul and Castrol in stock if you are interested, give me a call at 630-844-0089.

Wow, I'm surprised no one said ATE blue. At $10 a Litre its a 2/3 the price of motul, and has 90% of its temp range. I've run it in my race cars since day 1 and there is no reason to change.

I use ATE and I run my SRF a full season, never touch the fluid and never have an issue. I bleed the fluid on the Corvette when I change pads ~ 3 times a year. Seems to work for me and I haven't failed to stop yet.

I remember about three years ago, something happened to the year's supply of SRF. I had every type of pro racer calling asking if I had a bottle or a couple cases. Indy, Nascar, ALMS, and ect. There would be ten phone calls a day looking for the stuff. With that being said the SRF is the best. Everyone tells me I have a really good price on the stuff???
99 percent of all my brake fluid sales are Motul 600, or Brembo LCF.
Here is a little chart that we made a long time ago.
Brand Wet Boiling Point Dry Boiling Point
Castrol SRF 518°F 590f
Motul RBF600 420°F 593°F AP-600 410°F 572°F
Brembo LCF 600 399°F 601°F
ATE-Super Blue 392°F 536°F
Valvoline 333°F 513°F
Castrol LMA 311°F 446°F
Ford HD 290°F 550°F
Wilwood 570 284°F 570°F
PFC-Z rated 284°F 550°F
AP-550 284°F 550°F
The dry temp is when the fluid is nice and fresh. The wet temp is after it's been in the car for enough time to suck in some dampness.

The question was… what is considered the best brake fluid. I’m no veteran (only been doing this 2 years), but my vote is Castrol SRF. Learned the hard way. In reality it’s a safety item, so go with the best.

Good information Randy.
Looks like in the top 3 there will be no noticeable difference to 99.5% of the drivers so why pay $73 when $12-18 will do the same job, safely.
Interesting to see that Valvoline doesn’t appear to be much better than their oil. Living off the old stone age reputation I suspect.

I'd say good brake fluid is even more important for newer folks... they tend to over-brake and put a lot of heat into the system. And on street tires you may have no choice but to brake that much to make the corners... and they're less likely to be willing to pop a wheel off between sessions to push some new fluid through.

This is a great thread and very timely.
If not threadjacking or going OT, I wonder if we might expand this to other fluids (power steering, etc.) and make it a sticky...?
