I had a friend that went through this a few years back...he decided that silicone was THE way to go. If my memory serves me right, He did some research and found that the seals needed to be upgraded to handle the silicone. So he spent quite a bit of time and $ for that, lots of $ on DOT 5 fluid, throughly flushed the system, did everything right, and then had a soft pedal @ the end that he couldn't get rid of. Even replaced the MC and it was still there. Finally went back to DOT 3 and problem was solved. I don't remember any more than what I put here, but I do remember he was cussing for spending all that $ for nothing!
