[Fot] Source needed for single-flare brake lines

I have to preface this with my usual "Dunno about cars, only airplanes," but 
I never liked the double flare. You are bending the tubing back over itself 
with a zero bend radius, just inviting the tube to crack there. Why invite 
failure?

I wish I had a nickel for every cracked double flare I have found. In fact, 
I just wish I had a nickel.
