Does aviation brake fluid have a long shelf life? I have some that must
be at least ten years old. Is it safe to use?
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
cited....probably from somebody that sells it, but I don't see people
in a rush to change their brake fluid at annuals. If it ain't broke,
don't "fix" it. I did some research on it (admittedly a year ago, which
is forever in my brain), and I was not concerned.
Also, I've learned the "exercising" brake cylinders past their normal
limits is risky business, because o-rings go places they are not used to
going and do funny things, so it's best to leave that stuff alone, in my
humble opinion, FWIW. Of course it you fill the brake system from the
wheel up, this is not usually an issue. It's the bleeding through
pumping stuff that can get you in trouble.
