Silicone Brake Fluid

We have been using silicone fluid at the shop for years on the high end cars we build. You're system should be clean and free of any contaminants, including older dot3 fluid. You can flush the system with denatured alcohol first, just make sure you are dry when you refill with Dot5. For us, the major benefit was that it wouldn't take out a big buck paint job if we sprung a leak. I don't think any of my customers drive their cars to the limits of where their fluid would fail or not, so, I don't have an answer on that end of it. Just remember, it is harder to initially bleed a dot5 system, the stuff seems to be a bit thicker.
