I'm an old guy, been building hot rods forty years, been towing with a ton of variety of tow vehicles, I have NEVER changed brake fluid. Yes it is hygroscopic, but needs an entry point to introduce air, considering brake systems are sealed so the oil (fluid) can't get out, how does air or water get in?
Yes, you should change the oil in the tranny annd diffs, but thats just good maintenance.
The OCD people who change their fluid are probably introducing water when the take the brake reservoir cap off every week to check it. ;)
