Excellent post, Stealth, except avoid the red aviation fluid. Well, some of
the red aviation fluid. The stuff is
fairly flammable. Many designs use a hard aluminum line down to the brakes.
Overform the hard line, and aluminum will
eventually break, and possibly spew flammable brake fluid onto a hot break.
If that happens to you, you'll be damn
lucky if you have a quick thinking nephew handy with a gallon just of
anti-freeze or some such silly thing.

The airforce got tired for brake fires and had a drop-in replacement
formulated with a higher break point. If it is
good enough for the Stealth Fighter, it should be good enough for the Stealth
Pilot 8*)

8351 is the magic number the stuff is called (I think). I ordered a gallon
online for $20 or so. Enough for SEVERAL
airplanes. Big metal can. I use a sheet metal screw through a small o-ring
to seal up all the extra.

What about materials compatibility with standard O-rings? What about
toxicity and special handling requirements? Some fluids are quite toxic.
