I believe that the components must be specially designed for the silicone stuff. You can't put it in any car that recommends DOT4, even a brand new one.

The Ford HD stuff is the best buy out there, it's about 1/3 as much as the fancy ones and works about 95% as well. -Craig > -----Original Message----- > > Does anyone know if DOT 5 silicone can be used > if you are using all new stock brake hydraulics and hoses?
