Good suggestion, Jim
I have already submitted my report and photos to the RV list photo section (can't post a photo directly to the list), am told it should show up for viewing in a day or so. Also reported it to Van's but I don't expect anything from their end - although I did notice they are now offering the flexible stainless steel braided hose for brake lines {:>).

You might want to get on the RV list with that. There might be LOTS of failures, and yours is just the most spectacular fire so far.
I think it's worth publicizing as widely as is practical ... Jim S.

Yes, John - luck and a quick acting nephew {:>). The only answer I can come up with is that the aluminum line suffered a fatigue fracture which weakened the tube and the hydraulic pressure finally blew out the chunk. The line has a loop to provide flexing as the caliper moves in and out - but, flexing aluminum is not know for a long life. In all fairness, there are many RVs flying with this configuration - so the break might be attributed to my installation (stressing the line when I put the loop in it), material weakness, some damage I did not notice, etc. Had over 300 landings before the failure.

Wow, Ed!
You're luck the airplane wasn't consumed.
My question - how did that big chunk get blown out of the brake line?
Regards,
John

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 {:>)
