Vat of used brake fluid?
Around here, brake fluid gets flushed when the seized calipers get replaced... oh every few years or so. Road salt

This is what's wrong with the internet. Moisture-content is NOT over-rated. Moisture-content forces a chemical reaction, which in turn makes fluid acidic. Acid leaches metal. Thus metal content is the product of 'over-rated' moisture-content. Metal is the product of acid. Acid corrodes components and tears seals. Lest we forget the water boils.Not a surprise. Its the metals leaching from brake components that increase the mv. Unused 100 yo brake fluid would probably read the same LOL. Moisture content is way over rated for brake degradation-its the leached metals that do the damage IMO.
Moisture in brake fluid is probably the third most discussed topic here behind AZ on spark plug/lug nut threads and "what oil should I use?".

Moisture-content is over-rated. Right.... I see. Very good.
This is like the other brake-fluid myth that is forever spouted on here. It has the feds put a ban on color brake-fluid, this when the feds did no such thing. Be clear, no one ever uses DOT brake-fluid. You've never seen it, you never will. Because, break the seal and it's not DOT fluid. Brake-fluid can be any color. It might not be the 'right' color however the typical color for brake-fluid is brown.
And those cheapo brake-testers are not reliable, simply because formulations differ. Hence you can't calibrate the things. The pricier fluids are high-resistance when new. Thus these testers would indicate 4% or higher from fresh fluids.
Use a calendar, it will not lie.
As you were.

"Interestingly, moisture is not the main contaminant that causes brake system problems, though thought to be the main problem by many industry professionals."
What part don't you get? Phoenix says moisture is not the problem. If the driving force of the degradation process is moisture and it's not there ("not the problem"); how is this "acid" formed? Ford only found miniscule moisture and "acid" was not mentioned in their report. If "acid" is the issue, the engineers must have overlooked it. And please- lose the condescending attitude.Yes, Ford and Phoenix say the same thing. I'll type slowly.... Phoenix System sell a pH test strip, branded 'Brakestrip' , its existence verifies my words. It tests for acidity. Oddly, that'd be what a pH strip does?
For those without an English education pH is a measure of acidity/ alkalinity.
The litmus test?
I refuse to believe that's not taught in US schools.
The water degrades fluid to acid. Moisture is not the main contaminant to cause brake system problems, it's the product of the moisture, acid. And the product of the acid.... metal. Phoenix measure pH. What part did you not 'get' first time round?
And there's nothing so wrong with those cheapo testers, more they're not reliable because they don't test what we really need to look at. That'd be pH.
