silicone brake fluid

fordgtMember

What are the advantages/disadvantasges of silicone brake fluid with one obvious disadvantge of about $25 per quart. I have heard that it won't affect paint and does not attract moisture like regular fluid. Are both these claims true? Is it worth the extra $$$$? If it does not affect paint $25 bucks seems like cheap insurance. If you use silicone do the clutch and brake system still need to be changed every year?

thanks

The main drawback is that silicon fluid 'compresses' more than regular fluid.
This is noticed in a spongy feel to the pedal. Few people use it on the street.
In the clutch system, it makes a typically marginal system more troublesome.

The subject of silicone brake fluid has been argued to death the last 25 years. It attracts LESS water than hydrocarbon fluids but still gets some. It doesn't attack paint if you're sloppy. Its slightly compressible, reacts badly to altitude changes (one group of street rods totally lost all brakes at 7000 ft; they returned at sea level!) NO OEM manufacturer uses it, no race series uses it and the only value it has seems to be longivity in seldom-driven classic machines. And that should NOT be any Pantera IMHO!
