Ed - your brake problems have made me
rethink my own situation. after maybe 600 hrs I had the brake line snap
off at the fitting. I didn't give it much thought and just cut a bit off
and reflared it, thankful that I had put a generous loop in it originally.
it seemed to me that it had failed more because of that brake pad problems had
me disconnecting the line and the nut had started to cut into the line from all
the tightening. with a -6A no brakes is a big deal. I had to make
270 degree turns in Laramie once when I realized I had no right brake.
other than a personal bias against them, I wonder if the plastic lines are best?
I foamed my gear legs, so am not anxious to attempt replacing the brake
lines. my -8 has rifle drilled brake lines thru the center of the gear leg
which will be nice.

Yes, the aluminum wheel was protected by the steel rotor
between the fire and the aluminum wheel hub. In fact, I could even reuse
the inner tube. Might could have also used the tire, however, it was a
bit puckered and decided it just wasn't worth the risk.

No, I meant the wheel itself. Is it save?

Not certain to which aluminum you are referring,
Ken.
If you are referring to the wing skin, my best
guesstimate is - no. The paint was sooted but not burnt and
when I tapped the skin with a small coin, I got the same tone from the
unaffected wing's panel as I did from the one over the fire, so believe
the temper of the metal was unaffected. However, I suspect if the
fire had gone on much longer, the story would have been much
different.

Hi Ed,
Did the wheel get hot enough to affect the strength of the
aluminum?

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
