I have done a number of brake fluid conversions to silicone and flushed
out the system with denatured alcohol.  A pretty easy thing to do, but I
always bybassed the m/cyl in the process.  The m/cyl was always a rebuild
at the time as were the wheel cyls or new.  It was easy to get all the
alcohol out of the system by running dry low pressure air from my
compressor and just let it go for several minutes.  Never had a problem
with residual alcohol in the system.

Silicon fluid is a pain in the butt to work with in a clean system as you
MUST pour it in VERY slowly to avoid even a hint of bubbles.  Then
bleeding is OK but topping up must be done with no bubbles introduced to
the m/cyl.

For a daily driver car, silicone has no real advantage, except it won't
damage your painted surfaces, but for a garage/trailer queen, you might
have some benefits.  On a daily driver, you should still refresh it every
couple of years just as you should with Dot 4, 5, or 5.1.  Never use DOT
3 in the system.

Sicone fluid is a compressable liquid, has no moisture absorbing
properties, and tends to foam easily.  

There are extensive exchanges on this topic on the archives!  Lot's of
pros and cons here!!!!

And why have I installed Silicone in customers cars?  Because the
customers were convinced it was the best thing since the invention of the
wheel!  Usually replaced it soon with Castrol LMA.
