Reduce Brake Temperatures : Ideas ??

osbornsm · 10-09-2012, 01:29 PM

Hello All,

I have had several brake / track posts on here but now i'd like a little of your help.

I boiled SuperBlue brake fluid at Gingerman Raceway and i'm looking for ways to keep the rotor / caliper temperature down.

1. Would removing the backing plates / shield behind the rotors help with cooling?

2. I'm going to Motul 600 fluid next, but that's only 50deg F increase in dry boiling temp... would that be enough ? ? ?

I also rock the Motul 600 fluid, but I've heard that if you drive hard enough, even that won't cut it. It worked for me on my track day with no drama.

You can look into the Stillen brake cooling ducts. They run from the space next to the fangs directly back to the rotors in front.

And it probably goes without saying that you should upgrade the pads from stock.

For track use you want Castrol SRF. It's not cheap, but then you get what you pay for.

You will also want to look into getting some brake cooling ducts.

Could always look into the Stillen brake cooling kit.

I finally had a no brake fade day at the track with all of the above. I also used electric fans on my wheels in between the first three sessions, to force air inbetween. This left me with cold or nearly cold rotors by the next race.
I am using this set up less fans on the 22nd at the fastest track I've ever been to; Thunderhill.

I'm glad I could help!

1) Good brake fluid. Opinions are mixed on the Super Blue. Motul RBF600 gets good reviews. I've had a lot of brake temp issues along the way as I've been sorting out my setup, but I've never boiled my RBF600. Keep in mind that for track stuff, and especially with these better fluids: flush the fluid *at least* once per year, and bleed out what's in the calipers before each track weekend. The Castrol SRF noted above also gets rave reviews, but it's even more expensive than RBF600 and I haven't seen the need to upgrade to that, yet.

2) Stillen's brake cooling kit. It's not perfect, the ducts are a bit small, but it's a pretty reasonable compromise for fitment to our car and spindles, and it definitely helps.

3) Ti Front Pad Heat Shields - I use these in place of the factory pad-shims. They reduce the transfer of heat from the backplate of the pad to the caliper pistons (and thus to the fluid). Even the 0.5mm one can make things tight when fitting new pads+rotors, I'd think the 1.0mm would be a bit much on thickness unless you plan to shave down your fresh pads before installing.

Not directly a temperature countermeasure, but be sure you're running decent track pads as well, and the right rotor can help too (better cooling vane design, etc).

I told you they were POS
