Default Brake fluid cooler

I'm just wondering if there is such a thing as a "oil cooler" for the brake fluid. I looked around and didnt find anything. If there isnt, why not? I think this would be helpful in preventing brake fade if possible.

There is no such thing since this fluid is not really flowing, it is used as an incompressible fluid, so when you depress the master cylinder the caliper pistons build pressure and move very slightly. For a cooler you need for the fluid to be flowing and the overall fluid to build temperture. The fluid only builds temperature at the calipers. That is why the fluid is specific to handle high tempertures.

While there is no direct brake fluid cooler, there is an indirect method. A little over a year ago, there was an article in Sport Z magazine about a small company that was developing caliper based cooling fins. Test showed a reduction of over 100°F measured at the backing plate. It's called the Fade Stop Brake Cooler.

Unfortunately, they still don't have one for the 350 brakes. It's an interesting concept though.

The only other option that I know of of is a recirculator. Several years ago Brembo came out with a recirculator system that basically had a set of check ***** and two lines to the calipers. One of the lines would send fluid into the caliper and the other line would return fluid to the master cylinder. The idea was to give the returning fluid time to cool.

Ah. Gotcha MoodDude. That makes sense. I didnt think about the fluid circulating.
That fade stop cooler looks interesting. I see they have a hose pointed to them to ram cooler air in also. Looks like clearance would be an issue though.

It's a brake duct to force air across the rotors. There's a thread in this forum....

Interesting... but can you imagine the plumbing it might take? And what kind of fluid would you use anyway? More brake fluid that can take the temps? (Water certainly can't, neither can most oils right?)

Not quite the same, but these guys claim some good numbers, and they have Brembo application...

You can buy them from the Brembo and AP race catalog. It's being used in WRC with the tarmac front brake setups.

Edit: Enjoy unlimited braking !

Just looked - why are you concerned about brake fad when you have 355mm rotors on all four wheels? You already have a huge heat sink!

'Cuz he hasn't learned how to brake (yet) and he still overheats ?

I tried to get the ball rolling with the brake cooler, but apparently no one actually contacted the guy for test fitting in CA. He sounded like he was ready to do it. You know if it was released, people would be all over it...
