So my question:
How common is aluminum tubing in brake lines from a "per plans" standpoint. Does anyone else agree or disagree with the notion that this may be asking for trouble? Ed has said that he has replaced the offending part with braided hoses, so the problem should not recur at the same location.

According to Tracy, he had failed to tie the line to the gear leg. There is a loop at the end of the line which is only supposed to handle the slight caliper movement - nothing else. It's not supposed to handle movement of the whole length of the line unsupported along the gear leg.

Also, i never realized that brake fluid was flammable.. I did not ask Ed what flavor he used.. but what are the specs with regards to flammability on the different types of fluid?

Yes, the MIL-H-5606G "aviation" brake fluid is fammable. However, it's apparently not corrosive. A good thing for an alu airplane!
