Nothing wrong with DOT 3 if one designs brakes with plenty of overhead.

A lot is right with DOT 3 for it being less attractive to water, therefore longer life.

Didn't know exactly why.

Time spent looking at motorcycles, even Harleys, is never wasted.

In my former “pre retirement” life in the brake engineering world we tested most all brake fluids and quite frankly the very best I’ve ever seen was Dow brand HD 50-4 a dot 3 fluid. Far exceeded anything else in dot 3, dot 4 or dot 5.1 in every category. It was spec’d by ford motor company as their oe fill and unfortunately they switched to a much cheaper (absolute garbage) Pentosin Dot4. A big step backwards.

All that said, myself I put very little stock in the dot3 vs dot4 vs dot5.1, as all the testing we’d done showed the differences in claimed temperature & corrosion resistance is more advertising hype than real,,,, just use a good quality name brand (not pentosin) fluid, it’s about all you can do since you really don’t know the real quality of it.

The only real advice I’ll add is keep in mind that brake fluid is basically a vegetable based fluid (most synthetically produced these days) that is very hydroscopic (absorbs water) and WILL easily absorb into your skin so wear gloves. Also avoid any brake part contact with any mineral based fluids or greases like motor/transmission oils or greases or even things like wd-40 as it is a mineral based fluid. Only lube parts with clean brake fluid and only clean parts with either alcohol or brake cleaner.

Any introduction of a mineral based fluid/grease into a brake fluid system can and probably will ruin/swell the seals throughout the system no matter how small the amount. Just don’t do it or you could be replacing all your lines, calipers, mc’s and abs parts. Don’t do it!

I would like to recommend annual flush and bleed with DOT4 and have all your concerns solved. But, that's just me.
