Hi, Ed. "Hindsight" my hind foot! Us
aviators are ALWAYS "looking forward" . . . to preventing further occurances of
preventable accidents (Air Force safety jargon?).
Sincerely, you are "breaking new ground" in the
area of brakes. (no double pun intended on breaking a brake
line?) I've always known I'd never use plastic brake line (many have, and
have melted them and lost brakes during/after high speed taxi practice or hard
braking on landing).
You have just drawn a perfect conclusion from yet
another "brink of disaster but saved by the grace of God" event (God MUST love
you greatly!!): Aluminum does have crummy fatigue life. So maybe
I'll get some automotive steel brake line to fit or adapt to my Cleveland
aircraft brakes.

David, it was aluminum tubing which is what's called for
on the RV-6A brake system. However, in hindsight - thinking about the
low fatigue life of flexing aluminum, I think there are better
choices.

Ed, what kind of brake line was
that?

For those interested (and may not have seen them) , here
are a few photos of my brake line fire incident.
Big chunk got blown out of brake line as can be
seen from Brakelines.jpg photo. Effect of resin burning seen on wheel
pant photos. Once the line broke, the next time I depressed the brake
pedal, a fireball from the wheel to over the wing resulted from spraying the
hydraulic fluid over the hot brake assembly. The flash point of the
fluid is only 240F! I am going to investigate some stuff with a bit
higher flash point {:>)
