Douglas,
 I know what some people say but, here is my .02.... I have used DOT5 for a
number of years in some rarely used cars I have owned such as an origional
Avanti and a number of Corvettes I have owned as well as my 85 Carrera. The
reason I use it is the fact that it doesn't attract water as you mentioned.
I had a number of calipers and master cylinders go south from water
corrosion in a number of these cars.
 Honestly in my regularly driven cars especially thase with ABS I haven't
tried it. And our 83 URQ  is regularly used so I am using "Conventional"
"Blue" fluid in that one.
 Sorry for the bandwith on this.

Subject: DOT 5 (Silicone) Brake Fluid

Hey Listers!

This is one topic I've not seen in the months I've been a subscriber 
to the list (and with the search engine down, I'm not yet able to 
search the archives).

I know the conventional wisdom. Don't use it.

But the problem seems to center around it mixing with normal
(DOT 4) brake fluid. Apprantly, some reactive by-product
attacks the seals in the system.

But it would seem that if you flush every drop of DOT 4 out of
the system, you'd have no problems.

DOT 5 fluid is supposed to be superior, including but limited to the 
fact that it is not hygroscopic.

Does anyone here have any experience at all with DOT 5 fluid, and
has anyone ever succeeded in using it in an Audi?

tia,
doug
