I knew the SRF was sick, but that's pretty damn expensive. I think the Super Blue will work for me, too. A friend boiled the fluid in his STi (don't knock it - same brakes as us), so he is running SRF now.

 

Absolutely no knocking - I had my brakes fail to grab on me once last fall. It was late in the afternoon and I had on the track quite a bit; we were running 15 minutes sessions. I was running stock fluid and lines; I had purchased SS lines, but the fronts were incorectly made and the new ones were not back yet. For pads I was using Carbotech Bobcats.

I only had problems once, but that led to an "off" at about 75 mph. I went for the brakes; they were a tiny touch soft and they had no bite. Pressing harder didn't help . Personally I think most of the issue was over-heating the pads. Luckily the track has good run-off space and no damage was done. I don't feel that any of the equipment is to blame, I was just pushing harder at the end of the day and had exceeded the limits of my set-up.

For the comming summer I'll be running Ate Super Blue, SS lines and probably some new pads. I'm considering trying Performance Friction 97s.

 

ATE stopped making the gold variant of SuperBlue last year. You may be able to find a bottle, but it's not in production anymore.

 

Thanks for the info; I hadn't heard that.

 

Ford brake fluid has good specs. If I remember correctly, the dry boiling point is 500 deg F. It's the high performance brake fluid sold at Ford dealerships. It's cheap too.

 

I've heard about the ford brake fluid and even went looking for part number. I took the part number that I was able to dig up for the high performance brake fluid and called 3 different Ford dealerships; they all no longer stocked that PN had had superceeded it with another fluid. Since it was a different fluid with a different PN (and my wife would kill me if I started boiling brake fluid on the stove (joke, really)), I stopped the hunt. I'd be interested in hearing more about the Ford fluid if someone could provide a current part number and a link or scan showing some real specs.

 

Ford Heavy Duty fluid goes off really, really quickly, when I ran it I had to bleed the system monthly to keep them 100%.

Motul fluid is excellent and can stay in the system almost indefinitely. Expensive, but it lasts much longer and doesn't boil, not even with bright Orange rotors.

id go for the silicon based stuff, endless track hours and no fade!

 

I've boiled Motul on several occasions. R compound tires and aftermarket pads will put enough heat into the brakes to boil just about any fluid without some form of auxiliary cooling.

Edit: You should change your brake fluid before any track event. The boil point noticably drops after a while due to water absorption.

 

You're not driving fast enough!

 

are you sure about this... general consensus says that motul eats water and you have to bleed regularly to ge the water out nad if not you get corrosion.
