Kevin, et al,
I did a NTSB search from 1990 to present for Lancair accidents in Oregon -
there were 11 and none involved brake line failure.
I flew my 320 from 1996 until 2013 with Nylaflow brake lines
that arrived, along with fittings, with my 1989 kit (over 1200
landings). However, the lines in the stub wing to the brake were sheathed
with Tygon tubing to protect against nicks and abrasion and Adele clamps were
used to firmly support the lines about 6-8 inches from the brake
housing by screwing the clamps to the rear of the wheel casting.
For all I know, the buyer is still using those lines.
It is possible that unsupported lines flop around in the wind when the
gear is out and the line is weakened at the brake-to-line fitting

I think
the big problem is the plastic/rubber hose. You really don't want it to
fail on landing when you are really trying to stop. I believe a Lancair
brake line failed somewhere in Oregon, airplane went off the runway and
smashed into a tree, killed everyone.
Using Nyflow for brakes is kinda
creepy for
me...

Chris--
I'll be using the synthetic MIL-PRF-83282 brake
fluid. It has a "Fire Point" of 490º F, as compared to 360º F (?) with the
standard MIL-PRF-5606. The synthetic is approved for use with
BUNA-N.
John,
That could have been ugly. A friend of mine with
a Glasair had a rejected takeoff on a short runway. As he turned off the
runway, his plastic brake line melted and the 5606 hit is brake
disk.
