you won't flow more air. the velocity only goes up because the area is smaller and the same amount of air is supposed to flow through a smaller area. I don't think it will help the cooling of your brakes any. It may not hurt, but I don't see how it could help. Also, if the walls of the tube you are using are really rough, like corrugated dryer venting, that will cause a lot of turbulance inside the tube and restrict more. If I was using that type of tubing (which I probably will) I would not want any more restriction from making a smaller diameter.
