I changed and flushed all the silicone out and went with Wilwood 570. My main problem was header heat boiling the MASTER CYLINDER fluid. So why did I switch? Because water WILL eventually get in your brake system, it's only a matter of time. Bleeding EVERY race, etc. etc. will help.

IF water IS in the system (and humidity is very high in Hawaii) and that water is NOT absorbed by the silicone fluid the water will boil and cause an air gap in the lines, calipers or master cyl. when it does. This could lead to catastrophic and sudden brake failure. The water actually wouldn't "boil" I think it would "flash" (from liquid directly to steam).

Not taking any chances. I believe Wilwood has a valid point about NOT using silicone. Willing to risk paint damage over fractures (car body and MY body).
