aircrafts!

(USAF aircraft mechanic ‘69-‘90) any open can of MIL 5606 was disposed of

Automotive brake fluid is a form of liquid plastic and also has alcohol in it
to keep any water that might find its way into the system from freezing. That
is what we were taught in tech school. I have stored unused brake fluid (in
the steel container purchased from the store) and it went dark

Dr. Hsu and all,
No, I did not imply I REUSED brake fluid. That’s bad practice. I have
successfully put AGED brake fluid in my KR with good results.
I bought my present gallon can for my Beechcraft; I sold that airplane in 1993.
I rebuilt the brakes in 133RM 4 years ago with fluid from that sam

By the way John, I forgot to add that, in my eyes you are such one of a
kind aviator who can use or reuse just about anything on your beautiful
KR2, or altering anything you can lay your hands on, let alone to use some
used hydraulic fluid ...! Am I correct?!
My other question here is for Luis, an

Thanks John for agreeing with my suggestion to Mark! Nevertheless, are you
saying that most of what I said here were wrong or ignorant...?! No hard
feelings at all John, am just trying to stirring up a little here in this

Mark,
Though I’ve used old fluid before, Dr. Hsu is right on this one. At least

Mark,
I bought a whole gallon of the aviation grade hydraulic fluid for about $45
not long ago, so if I were you I'd choose to buy a brand new gallon or
bottle of ave fluid instead, simply because it's not worthy of taking any

Here is more than you ever wanted to know. BTW, I use Texaco #15 (5606H
equivalent) that is at least 30 yrs old in the KR and my Cessna.
See #4 below. If it meets that STD then its fine according to the military.
Current spec is MIL-PRF5606H

Just use it. I've been using the same one gallon can for 20 years, and
it's fine. I'm sure somewhere you can find some short shelf life
