How effective is Dali brake coolers for stock brakes?

[kenjiMR]

I'll be at Thunderhill on August 1st, but I was wondering how much help the air coolers provide. I have the parts from Mark, but I havn't installed them yet. Its just such a pain in the a$$ to remove the dust shields I think.... I'm not looking forward to doing it. My brakes are completely stock still... I don't even think I have Motul brake oil.

If you are using them on bone stock brakes:

useless if you are easy on the brakes(begainner)

useless if you are hard on brakes(experienced, or dunno how to drive)

I have them, and recommend them. I still experience brake fade on the OEM pads/rotors, but not as much as I have previously. In fact, even in 100 degree Texas summer heat, I experienced less fade with the coolers installed than I did in cooler temperatures without the air deflectors in place.

One other item: they are large enough that when installed, they will "scoop" air up from under the car and onto the brakes. A lot of people probably wonder how effective they are sitting behind a radiator getting hot air... install them and then look under your car from the front.

The dust shields are easy to remove. Just make sure to have an impact screw driver. After that, it's a piece of cake. The DIY is online (you can find it off my site).

I used sheets of aluminum from a hardware store to shape brake ducts that seem to work very well.

The best easy upgrade you can do first is pads and brake fluid flush. Speedbleeders are highly recommended. I have also have better luck with ATE Superblue than Motul.

Keep in mind that if you're thinking of installing cooling ducts to run air to the brakes, those dust shields can serve a useful purpose. On mine, I had a hole cut in the dust shields and a flange welded on, and the ducts are mounted to the flange.
