good thread, thanks.
also another good read, more on the subject of fade:
from this article
"Our objective here was primarily to test brake fade, not stopping distances. Assuming a brake system is properly balanced, strong enough to lock a wheel, and not yet hot enough to fade, the stopping distance is largely a function of tire traction, not brakes.
Think of it this way: All brake systems, stock and aftermarket, are able to activate the ABS, so how could a stronger brake shorten a stop? Eric Dahl, a brake engineer from Brembo, put it this way: "Don't expect the brake kits to stop you sooner, but expect the 20th lap to feel like the first."
