Castrol SRF brake fluid
After boiling Motul 600 a couple times in the past year, I am biting the bullet and going with SRF this season based on the rave reviews i have read. I will also be running stoptech ST60 BBK up front and stick with stock rear setup. Carbotech xp12/xp10 pads are working great and centric rotors in the rear are holding up well.
Curious how often those of you with a similar setup have to bleed brakes? I saw a couple threads where guys said they could bleed once a year with SRF. That sounds like a pretty amazing claim. Is SRF that good?

Mark do you have cooling? you don't say, but if you are having that much trouble then I would think you will need cooling even with your new mods. I run SRF in my racecar, and Stoptechs on the street (against my sanctioning organizations rules), so I can't comment directly on your issue.

My hope is the ST60 BBK will dissipate heat much better to where I could run the motul 600, but I'd just assume go with the SRF based on what I've read on here. Much higher wet boiling point than the motul 600.

I have been using the SRF for 3 years with great results. I don't W2W, just TT with CL pads. Basically I bleed in Feb, and I have been good for the year as stated in some of the post you read. I will point out that I only do 5 - 6 weekends per year. Just my 02.

I have tried Motul 600, High temp Wilwood, ATE Superblue, Elfalub and Castrol SRF. The Castrol is absolutely the best of the bunch and by quite a bit. Couldn't go back now and given the money I spend on pads, I can't complain about the fluid cost. I too don't bother bleeding the brakes during the season (although I do have cooling ducts)

my same experience and use... I do have the quantum/lambert cooling hoses on the front, so I think the OP should be able to run the same?

If your cooler is by the radiator it shouldn't matter-- this kit uses the factory plastic duct from under the front fascia to just in front of the a-arms, then extends it with hose and an aluminum adapter to cool the brakes much better.

WTF kind of hack job did they do? I thought C6 brake ducts drew their air from an NACA duct on the bottom of the bumper? Even on the C5 they're way out to the sides beyond where you'd stick a trans cooler. Can you monitor your trans temps? Do you have any wiggle room with them?

Motul 600 has one of the highest boiling points of any brake fluid - 590 degrees. If you're boiling that then you have an issue. It might be the way you're braking. Do you stay on the pedal for a long time?

I think the difference with the SRF is the wet boiling point. I know plenty of good drivers who seem to boil motul 600 after a few days at the track. I'll be interested to see how long I can go without bleeding the brakes with SRF plus ST60 BBK up front and basically stock rear setup. I plan on around 8 HPDE this season and I'll keep everyone posted.
