when I went riding yesterday I noticed brake fade, I think from overheating. It's the older Polaris brakes that are not liquid cooled. Today I routed a large tube directing cold air towards the brake. Am I creating another problem if snow/water gets onto the brakes?

This is just an opinion... disc brakes on motorcycles and cars work in the wet, so I dont see why snowmobiles wouldn't. My concern would be that you would be increasing the possibility of getting water around the carbs . As you know, some wet could be sucked into the carbs which is risky at best, but also the moisture can get around the cables and freeze during a stop in the action. Ive had problems in the past with older sleds after drift hopping where snow got in, melted and then froze over night . Some how the water got into the choke plunger area and caused them to stick open . took me awhile to figure that one out too. I dont think I would leave it on.

I've seen alot of brakes with ducts . Look at pre 97 ZR's or new Vipers. The cooler the better,Polaris has known this for years with thier L/C brakes

The only thing i would be worried about with your air tube would be getting snow on your rotor. A nice hot rotor doesnt take to freezing cold temps. It will warp your rotor and give you pulsations in your lever.

If you want to step up to a better braking system, you could either look at the new Polaris/Hayes braking system, or one of those wierd looking wave rotors, that increase cooling.

I have the Hayes/Polaris brakes on my 2000 Indy, and i can consistantly stop from 60 mph without any fade at all. This is without the liquid cooling lines running to the brake.

Polaris is my way out - Other people just use a door.

trying to keep it cheap. No wave rotors for me! As for sucking snow and crap into the carbs it's routed so air misses airbox. I'll get a picture of it and post it soon.
