OT, Auto brake fluid questions (split topic)

So does that mean the auto brake fluid has alcohol in it which would explain why it picks up moisture and corrodes things? it goes to a question that I posted a couple of weeks ago that died unanswered. Why not use 5606 in the car? I'm really thinking of an older vehicle pre ABS.

Dave, older cars can still use current DOT 3 or DOT 4 fluids. I would advise against using any fluid other than automotive brake fluid. Auto brake fluid has a high boiling point and that is important. Automobile brake systems generate MUCH more heat than light aircraft systems, and MIL H 5606 is flammable. The older drum systems are particularly susecptible to wheel fires when the wrong fluid is used. (Auto brake fluid isn't alcohol based, ...it's ether based.)

I rub automotive brake fluid on my re-arched tailspring to prevent breakage. Basis for approval-- the devil made me do it.
