Maintenance Needs on a Ford Chassis

Brake fluid ought to be replaced every few years--I've read three, but that may be a bit unnecessarily conservative. It tends to be somewhat hydroscopic (i.e. absorbs water from the air) which lowers its boiling point, which causes brake fade or failure sooner under hard use, and can cause corrosion in brake lines etc.

Overall, I agree that it sounds like you're on the right track.
