Reply to "silicone brake fluid after 20 years"

Water is present in all fluid in suspension. One of silicones first application in race cars was the hill climbers. They liked it because of the high boiling point. They soon found it's pitfalls. While normal brake fluid can absorb water, silicone cannot. What this means is every drop in suspension which exist from day one settles out in the low spots.

That single drop settles int he calipers and if the calipers get hot enough, that one drop boils rendering the brakes useless. Pretty much any competition if silicone is used the practice is to flush it before every race.

A non-silicon hygroscopic fluid can absorb around a table spoon of water without loosing one's brakes. A silicone fluid can loose it's brakes with as much as one drop in the system.

I don't compare it to regular brake fluid in how long it looks good. With regular brake fluid most manuals tell you it should be replaced in a 2yr minimum yet when is the last time any of us changed brake fluid. Yet silicon is recommended before any performance event or yearly at minimum.

It's great for collector cars and parade cars for the reasons you state but that is why guys with performance cars avoid it.
