Thanks for the explanation. Also it's good to point out that DOT 3 and 4 is NOT compatible with DOT 5 and can cause catastrophic brake failure. But DOT 3 and 4 is indeed fully compatible and can be mixed with DOT 5.1 brake fluids.
So DOT 3 will not absorb water as quickly as DOT 4. Why you should not “upgrade” your car’s system with DOT 4 unless you start changing the fluid more often. DOT 4 does have higher performance when maintained and changed frequently but whatever the higher composition that gives that higher boiling point, it’s the portion that wants to absorb moisture.
