W.R.,

Are you talking about Silicone Fluid? That stuff has lost popularity, and I/m sure it is because of the reasons you stated. There is now partially synthetic available that will mix with regular brake fluid. I used this stuff in the clutch system on my Vette because the line including the rubber part, goes right by the catalytic converter and everything gets fried. Isn't GM engineering impressive?

If the fluid is being changed once a year AND you're not road racing the car, plain old brake fluid will serve well.

Have a great day,
