Lubner, I would think that would make it possible for someone to make a line of them again as there gotta be a shortage on the market. Maybe time to organize a group buy if there's enough interest.

Wraithracing, well that makes sense and it is a similar concern as swapping refrigerant medium in the AC, compability issues. I thought it was some property with the silicone fluid itself. I have converted one car already when rebuilding that brake system and there's not been any issues with the brakes so far after a year. I blew out all the lines and bled thru enough DOT5 to fill the system twice just to assure there was no remnants left of old fluid, and that car has a way more complicated brake system than any non-ABS Ford ever made that I know of, a triangular brake system. Volvo liked to over-engineer their stuff back in the day.
