If the brake fluid boils during hard sustaind braking, you will loose brake pedal since fluid is compressable and air essentually is not.

Isn't it that air is compressable, and fluid is not? (i.e. air can be compressed) Just thought i'd clarify.
OK, I guess I need to review my rusty High School Physics. When you try to brake with vapor instead of fluid the calipers don't get the pressure needed to make them squeeze the rotors. I guess that you would be correct because a hydraulic system must function without compressing the medium. If there is an engineer in the group that better knows the correct verbage, please speak up.
Yes, brake fluid is nearly incompressible, while brake fluid vapor is highly compressible. This means that when you apply pressure to the system, the vapor will compress instead of moving out of the way, into the caliper. There should be no air in the system at all, I think you meant brake fluid vapor, which is a gas, like air.
And yeah, buy 4 SS brake hoses and flush/bleed the system. It's always a good idea, and from what I hear, the combination of new, clean fluid and stiffer lines means much better brake feel. It's on my to-do list.
