I am thinking that a heat shield should work perfectly fine. On the Porsche 
944 Turbo the turbo and downpipe are just a few inches from the brake MC, 
and they added a heat shield to protect it. I have heard of people who 
remove the shield for whatever reason actually loosing thier brakes because 
the high temps from the turbo are enough to boil the fluid in the MC and 
lines. The small heat shield that runs from the shock tower to the firewall 
and wraps arround under the MC protects it from a turbo's heat, so any heat 
shield you make should be effective for "just" the hot air from the rad fan.
