Castrol Response is what I use in my mountainbike disc brakes. Cheapest place I found it was Kmart at about $NZ7 for half a litre.

I just bleed it through the system untill it came out of the bleeders.
The reason I used silicone was not for the boilling point , but the long life and lack of wear it gives brake components with little corrosion.
I will in time do all of my vehicles with silicone fluid.

you're game.
I'll never use a silicone fluid in any of my vehicles (or mtb) as I like to have a consistent pedal.
Silicon brake fluids are compressible and they foam, not the ideal situation. No one in motorsport use a silicon fluid for very good reasons. (the base of Castrol SRF is different, it's a silicon ester and virtually incompressible)
