Reply to "Brake Fluid"

Jan,

DOT 5 is silicone based and not compatible with any other brake fluid. There is also DOT 5.1 which IS compatible with DOT 3 & DOT 4 brake fluids.

I know of no way to tell them apart.

If you cannot contact the previous owner, or the shop that maintained the vehicle/installed the brakes, the next safest thing to do will be to have the system flushed thoroughly with a power bleeder and refilled with DOT 5.1.
