silicone brake fluid?????
I have never flushed a system and replaced it with silicone brake fluid, but i have a 65' Mustang that had all new components, like a master cylinder, new lines, calipers and proportioning valve. I put silicone (Mortorcycle type) fluid about 4 years ago, and i have never had a problem. Some say it will draw moisture, but my car sits a majority of the time, through mild temp changes with no problems! I have never even had to bleed the system, and it still works as good as the first day i put it in. Good luck.... FOMOGO

I have heard it is OK with all new components but won't work with the old components that have had std brake fluid in them. You might try the guys in: Suspension, Tires and Wheels forum. There is a newer spec DOT-4 fluid that has a higher boiling point than DOT-3 fluid and is compatible with the DOT-3 fluid.

I've been using silicon fluid for years. I started using it in custom motorcycles because it wont eat the paint if you spill it. It is non hydroscopic (doesn't attract water) and therefore doesn't corode the internals of your brake system like regular fluid. I've never had any problems with it.
however: do not use it in ABS systems as it can foam from repeated pulsations. I also would not use it for racing, towing or if I lived way up in the hills where you might get it to foam from continuous applications of the pedal. It has never had this problem in my truck over the last 15 years.
