Everything I remember hearing/reading says to stay away from the silicone
fluid. Can't recall the particulars. I would go with a good hi temp brake 
fluid like
ATE super blue racing fluid, Motul or the Ford heavy duty fluid. Everyone 
has their
favorite and I use the ATE or Motul stuff.

When you upgrade to the 2 piston front calipers you also need the brake 
rotors.
The stock TQC rotors don't work with the later calipers. And something I 
learned
just the other week from a friend who did this mod to his 84 TQC, you need 
to
change the front/rear brake proportioning. With the stock TQC proportioning 
valve,
the rear brakes are just along for the ride and aren't doing any of the 
braking work.
At this point I am not sure of the correct Audi proportinong valve. I have 
seen another car with the 2 piston calipers running an adjustable brake 
biasing valve, a solution which works, but not sure if it's DOT legal for 
the street. Best of luck with the swap.

If anyone else has info on this upgrade, I would be interested in hearing 
it. It's on my list(along with a couple hundred other things).
