Nobody that I know of uses silicone fluid on the track. 

The negative charactersitics  (such as its compressability)  of it far outweigh the boiling points on paper. Most everyone that I know uses a synthetic DOT 
3/4 compatible fluid (I use Vavloline Synpower). Even the high boiling points don't work in practice as the water that invaribly does get into the system pools 
in the wheel cylinders and boils much quicker than the water-laden glycol based fluids.

Based on my very negative experiences with DOT 5 in street driven Corvairs (including full brake failure in a customer's car), I would never ever recommend 
them for anyone who uses their brakes heavily on the street... only for rarely driven trailer queens.
