Brake fluid comparison list 2010
Time to post up the list again for 2010 because there are new products and some updated pricing since the last list.
Prospeed RS683 with a 683F has the highest dry boiling point and also the highest wet boiling point of 439F:
See: http://www.rs683.com/abc.html\
sold here: http://www.pegasusautoracing.com/pro...asp?RecID=1036
A few other new players since the 2006 list: Motul RBF 660, Endless RF-650, FERODO Super Formula . Also PROSPEED GS610 is discontinued.

DRY:683F -- WET:439F --- PROSPEED RS683 (new since 2010)
DRY:590F -- WET:518F --- CASTROL SRF
Some fluids on the manufacturer's web site did not specify wet boiling point, so I used the relevant DOT 3 value.
Water absorption:
DOT 3: This brake fluid has a glycol base with additives. It is clear to amber in color. It is hygroscopic (meaning it absorbs moisture) and has a minimum dry boiling point of 401F (205C) minimum and a minimum wet boiling point of 284F (140C). It will absorb 1 to 2 percent of water per year depending on climate and operating conditions.
Castrol SRF remains as always the Wet boiling champ. I don't know of any other new ones.
Now of course boiling temp is not the only thing to consider, as compressibility, water absorption rate, recovery, viscosity index, etc all play a part. But without a brake dyno, that data is hard to get.

Re: Brake fluid comparison list 2010
Thanks for the update Claude.
When I think about brakes and fruid, specifically the heat specs, I try to think about the whole system and what the goal is. For most of us, who needs the highest boiling point? If your brake system is developing and failing to shed enough heat, while sure you don't want to boil the fluid and wind up with no pedal, you are paying in terms of something else. The rotor life must be terrible. The wheel bearing life must be terrible. Your tire temps will be running higher as well. If you have to run fluid with a 500 degrees F wet boiling point, and you have to run a pad that still makes good mu at 1700+ degrees F, then maybe you don't have enough rotor diameter/mass and/or cooling.

Re: Brake fluid comparison list 2010
By the way, i've spoke with Prestone (making the Ford oil rated at 550 and 500F).
They say the oil in the 500F bottle is the exact same as in the old 550F. Wich one is the right temp I don't know, but i've been using this oil with great success at 6$ a bottle. I bleed often whatever the oil.

And as for brake heat, an endless concern. Thinking of a fan solution.

Re: Brake fluid comparison list 2010
You do have more V-squared than most of us. Wheel fans - Yes. Drilling holes to mount them - Uhhhhhhh...
Scott, who is sure you can get good brake fruid in Canadia...

Now the most bizzare thing is this quote ..."but it's more resistant to pad knock-back than other fruids" Who said this?

Re: Brake fluid comparison list 2010
Castrol SRF is what i run, bleed the brakes every now and then...
I used to run ATE, worked great in the H4 car.

Re: Brake fluid comparison list 2010
SRF is the best but ATE is not far behind if you flush it often. If every race you start with a fresh bottle of fluid throughout you can get the same performance at a lower cost. The AP 600 is also very good so take your pick. The important thing is to always have fresh fluid because it spoils quicker than milk!

Re: Brake fluid comparison list 2010
I've used Motul RBF 600 for many years in my tracked cars, since it has a much higher dry boiling point than most other fluids, and it has always worked fine. This year I decided to try the Prospeed RS683 and it has worked fine too.

Re: Brake fluid comparison list 2010
I HAVE to run SRF in the datsun or Im flushing fluid out every session. Might give the new stuff a try when its time to flush the system again.
