Bob, 

Water and Brake fluid don't mix, you should know that.  If water is
virtually incompressible why isn't it used in hydraulics like front end
loaders?  They don't get hot enough to boil it away.  The Castrol is more
moisture resistant than Dot 3, LMA stands for Low Moisture Activity, its on
the bottle.  By the way what exactly makes the fluid so dirty when it's old?
Water.  And just to prove the point why do the brakes feel better with new
fluid?  Its because the fluid acts as a liquid rod and there are no
contaminates in the fluid to affect it's work.  If you still think I'm wrong
put a little H2O in your master cylinder, pump it around the system and tell
me the brakes aren't bothered by it's presence.

And you are correct when you state Dot 4 is not bothered by heat as Dot 3.
That's because since the 4 doesn't absorb water the way 3 does.  Therefore
when it gets hot there isn't as much water to boil, causing fade and
possibly VAPOR LOCK!!!!!

P.S.  That's why silicon (dot5) is good, although impractical.  It won't
absorb water.
