ive used it on the brit and european cars that were really bad a rotting it did the trick, ive also used it on the pontiacs with good luck. added benefit it wont eat paint. its not as good at sheding heat but im not road racing

I would not use that sh+t if my life depended on it, Terrible spongy pedal feel, impossible to blead, any moisture will still pool at the bottom of the wheel cyls, more money, and hard to convert back, need to flush the entire system

I would avoid it like the plague, i used it in my 64 and im sure it lasts, but the pedal characteristics and bleading make it a total pain

I don't have much experience with the silicone brake fluid but I did try it in my 62 Impala with manual brakes. As beaumontguru said, the pedal had a mushy feel to it. I went back to the regular stuff and it was fine.
It might be OK with power brakes but it wasn't good for my manual brakes.
It's nice that it won't harm the paint if you spill it but I'd rather have nice feeling brakes.

Thanks for the input. I read your interesting comments then went to google and typed in Dot 5 problems and got many links with a lot of stories,

Might just forget about DOT 5 as my main concern was that I was going to replace the master and have it repainted and didnt want the brake fluid to clean off the fresh paint, leaving a rusty part Everything else is working fine, no point in messing it up............

Thanks.

I know this a very old posting but i did find it very interesting to say the least. I have used nothing but silicone brake fluid since 1990. I have used it in my 57 Pontiac since 1996, in my 74 Chev wagon since 1995 and in my previous 57 Chev since 1990. I am mystified by the comments here because i have had no issues at all....... none. I continue to use it today and would never use that prehistoric crap. Cheers.

The brakes in my 72 Nova are just going back together and I was thinking about looking into the Dot 5.

There will be some of the old stuff in the rear cylinders and the front calipers that I will push out when I refill the system. How clean does the system have to be to make the change?

Mike, keep bleeding with as much of the good stuff as you can to get that junk out of there.

Thanks George, I just wanted to make sure that mixing them, even a little, isnt a problem.

Mike, i have never had any issues at all in 30 years and yes it is very nice that the stuff does not ruin your paint. You can rub that stuff on your paint all day and no ill effects. The prehistoric stuff will peel your paint right down to bare metal. Cheers.
