Somehow, somewhere (RVlist I think) I'd learned that
ATF was almost identical to this military brake fluid, but since it is much
easier to get, is why I originally went with it. I'm glad to be done with that
experiment.
DOT 5
is good to 550F, won't absorb water or harm paint like DOT 3&4, is readily
available but is $35/litre. I've already replaced all the seals in my brake
system with Viton, so compatibility shouldn't be a problem. So far the brakes
seem to be perfect.
I also read somewhere that (this
list I think) that the short hose for a grease gun was perfect for the brake
line to calliper. This sounded like a great idea and since we happened to stock
a box of new ones at work for the oilers, I liberated a pair of them for use on
my brakes. Unfortunately with the cold, I decided that it was a job that could
wait until warmer weather and I didn't want to start an unnecessary job
that would cut into any chance of flying. Any thoughts on weather this is still
a good idea? Better than the ATF idea :-)?

Rusty,
I went with the new high flash point aircraft brake
fluid (MIL-H-83282)- flash point is 450F vs 240F for the
old stuff. I had to get a gallon of the stuff (enough to probably
last me for years and years and years), but after the fire, I feel a bit more
comfortable that it won't go up with the temp a little over the boiling point
of water. I considered some of the auto brake fluids - but have heard
some horror stories about incompatibility with aircraft seals - I know there
is some DOT formulas that supposedly are compatible - but did not feel like
experimenting {:>)
