EGA, I don’t think I would like to try running modern braking systems with any water in them, in fact brake fluid changes are part of the service cycle to eliminate any water that may be in the system, brake fluid is very hygroscopic, I take you point about the historical use of water in braking systems, it is a very good hydraulic medium.

No, indeed; I take it that the objection to water is that it corrodes the braking system and if it boils will adversely affect braking.
I haven't been able to confirm the Miller reference but note that the winning 1921 Duesenberg Grand Prix car had water-operated brakes; possibly the emphasis in those days was on going rather than stopping!
