That is correct. Moisture will always find it's way into a braking
system. With non-silicone fluid it dilutes the fluid. With silicone fluid it
remains free (I guess it's imiscible with the fluid). Under certain braking
conditions the moisture can turn to steam. I haven't heard the moisture
sinks to the low places - it certainly either rises or sinks and settles
somewhere.
So, Silicone or not, it's still necessary for brake fluid changes - how
often for a silicone I don't know. I do an annual fluid change on my Sprite
irrespective of the mileage in the year.

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
