Front to Rear Brake Pad Friction Balance

In reply to GameboyRMH :

I could be wrong but the amount of air needed to cool the brakes would be pretty negligible. 

In reply to Tom1200 :

True, but the issue is that to get air into the brakes from the outside you'll end up having to move a lot more air, either just blasting a ton at the spokes to get some past the spokes and into the opening around the hat of the brake disc, or using wheels with fanblade spokes that will make a bit of a reverse-sucker-car. A folded aluminum duct to route air from a traditional inboard-fed inlet to the hat on the outside would get the air exactly where it needs to go and have similar aerodynamics to a regular brake duct.

This might be a very stupid suggestion, but instead of forcing air into the outside of the wheel, could you use a backing plate to suck the air out of the inside of the wheel, with maybe something like a naca duct behind the wheel facing backwards?  That way you wouldn't have to fiddle with trying to duct air to the outside and it wouldn't force more air under the car.

Sucking air out of the back of the wheel with something like a ducted backing plate that wraps around the outside of the disc going to a low-pressure area around the rear-center of the car should do something, although I suspect it would be hard to get enough airflow especially at lower speeds.

You could boost the airflow with a high-powered extractor fan and make something like a McLaren/GMD "virtual longtail" although the fan blades would need to be cleaned pretty regularly...

I knew a World Challenge racer who used bilge blowers inline on his brake ducts.

I haven't found any pricing on it though.
