Synthetic brake fluid

[Andrew Buc <abuc@ibm.net>]

I recently saw some Valvoline synthetic DOT 3/DOT 4 brake fluid at the
store. I gave them a call at 1-800-TEAM-VAL and got the following info:

This isn't a silicone fluid, as I guessed from the lack of a DOT 5 rating.
Supposedly it makes your brakes more fade-resistant. Like any non-silicone
fluid, it's hygroscopic. It won't hurt natural rubber seals. I finally said,
"Sounds like it's more nearly like conventional brake fluid than a silicone,
but better," and the guy on the other end agreed.

I haven't tried the stuff, so make of it what you will.
