you can use silicone if you want to, be sure not to mix it with normal brake fluid though as they don't get on well and results in poor
brakes.
Brake fluid you would find in a road car is Dot 4, Dot 5.1 has a higher boiling point and is better for faster applications. I don't know much
about silicone fluids but I think its also knows as Dot 5.
I'm going to use dot 5.1 in my indy when ready for it.

tell me if im talking crap here....lol
dont use silicone unless your brake system is spec'd for it.
Dot 5 is silicone
Dot 5.1 isnt.

I have been a fan of DOT 5 (silicone) for a long time. I used it in my Indy. It works fine for vehicles which don't do a high mileage and which
might stand around for long periods (say laid up over winter)
You should only use it if all the components are new and have not been exposed to mineral fluid.
Ordinary fluids DOT 4 or DOT 5.1 are ok but they do attract moisture which can lead to corrosion of the components. They should be changed every
couple of years but do give slightly superior performance if you are racing say.
A bit of a controversial subject but hope that helps.
Cheers

Bear in mind that new components may have been assembled using conventional fluid and even that small amount can cause big problems.....

After 12 months in the UK climate the boiling points of DOT 5.1 and DOT 4 are only a few degrees different.
The higher the boiling point when new of a conventional glycol ester brake fluid the more hygroscopic it is. Racing fluids are more hygroscopic than
DOT 5.1 which is more hygroscopic than DoT 4.
DoT 3 fluid is pretty well history now and mainly restricted to the USA.

Yes because conventional glycol ester fluid is hygroscopic and DoT 5 isn't its the small pockets of conventional fluid that will contain any
moisture that gets into the system.

DOT5 (silicone) is also excellent at holding air bubbles, which means that you nearly always get a softer pedal than with glycol based fluids.
The fact that major players such as AP don't recommend using silicone
fluid in their products is reason enough to avoid it IMO.
