[Spridgets] FW: Racer type question..

Well put.

And I still believe that the silicon brake fluids are not hydroscopic.
Thus moisture that will get in there, sinks to the low places and rusts
whatever it is in contact with; sooner than with DOT 3 fluid. ...bill in

I'm with Bill below but I would add one of the reasons for any water build 
up (It comes IN the fluid hydroscopically) is not changing the fluid every 
couple of years.  Old fluid is old because it has absorbed airborne moisture

until it concentrates sufficiently to distil from the fluid as puddles in 
the line.  The moisture content turning to a gas by heating is the reason 
for true brake fade - as opposed to burning the braking material.
I don't particularly want to open up another 'can of worms' but IF you are 
having a new braking system (that is everything in the brake system) and one

that is not contaminated with ordinary braking fluid it is a good time to 
change over to silicon fluid.  If it is just new calipers and nothing else 
don't do it.  If the seals have been lubricated with ordinary fluid prior to

assembly, don't do it.
