I've used Silicone in my Titan Formula Ford for years. The pedal isn't
quite as firm as with regular fluid, but it's a matter subtle feel rather
than any real substance. With formula cars we never test the brake system
in terms of temperatures. Probably wouldn't suggest it in any production
car as those brake systems are seem to always struggle with brake fluid
temps. The DOT Silicone I've used says its OK to 500 degrees. Even thought
Silicone is discouraged for racing, in the light formula cars it seems more
than adequate and what a life saver on restorations.
