Re: CAUTION ON THE USE OF SILICONE BKAKE FLUID IN ESAMATIC BRAKE SYSTEMS

I don't doubt that people have had failures of Treadle-Vac units, some perhaps due to incorrect rebuilds or other factors but my own experience over many years and miles is quite the opposite. Many years back I drove a 54 Patrician as an everyday car for 15 years and my current 56 for about 11 with no problems and although I know of folks who have had their units rebuilt for peace of mind, I don't personally know of anyone who has ever had a unit fail to the point of no brakes. Leaking brake fluid into the vacuum section, yes -- but outright failure - no. The same type unit was used on millions of GM and Ford products in that era, perhaps researching their service bulletins might be enlightening.
