After we restored our '67 GT500, which included everything new in the brakes, we used silicone brake fluid with good results. It's actually a lot nicer to use because it's not harmful to paint. I understand that its boiling point is lower, so in racing situations it wouldn't be the right stuff. But for street use it seems just fine. Roger I think we did a survey a long time ago on the proper brake fluids for our Shelbys. What type brake fluid do you use? Is silicone a no no? Let's have your thoughts and I will publish the results, if there are any variations in useage, similar to the oil survey we did a year or so ago. Ron
