I changed to silicone brake fluid 19 years ago and have had no problems whatsoever.  

And based on recommendations from the list I didn’t flush anything. I pull the silicone fluid in and bled the brakes until it showed up (NAPA brand is purple) at the bleed screws. No muss no fuss, no problems, and I get to keep the paint in the engine bay.
