On the subject of brake fluid, when I took the TR-4 apart and removed all the
brake lines, master cyl., etc, the brake fluid was very clean, almost clear.
This was surprising because supposedly the car had been sitting for over 10
years. However, it didn't look like brake fluid as it was a very yellowish
color. I'm guessing it is a silicone brake fluid but don't know, never
having used or worked on a car with silicone fluid. Any guesses? Is
silicone fluid preferred over the standard fluid for racing? Thanks.
