Silicone Brake Fluid???

[Degnol]

Since my brakes, lines, master will all be new, should I go with silicone brake fluid?
I've heard good things about it, but no bad and that's unusual. I guess it is pricey?

Not unless you know that everything in your system is compatible with it...

Castrol LMA(low moisture activity) dot 3/4 has always been good enough for my junk....rover included

Dot 5 is a bit more spendy. I put it in my '63 Merc and it works fine. I noticed the pedal feel wasn't quite as firm though.

The restoration guys I talked with recommended the 100% silicone for any car that was put in storage for long periods of time. The car sat since '64 and all the seals needed to be redone when I got it. Fun car to drive I just need to rebuild the generator on it. I have only worked on alternators so far.

Besides a slightly higher boiling temp (your fluid shouldn't get hot enough to boil dot3 anyway), the only advantage is lack of its hydrophillic (water loving/absorbing) nature. I hate the stuff personally due to incomatibility with any other type of brake fluid. And it is three times as much. Also, if you ever choose to switch to normal fluid, flushing the lines with isopropyl might night be good for the rubber seals.
