Hemmings Motor News is also of the opinion that the BTV isn't safe:hemmings.com/hmn/stories/2009/09/01/hmn_buyers_guide1.html

Eric. The Mercedes article u found is probably the most amazing and convicing INDEPENDENT evidence found thus far. YOU are an amazing man for having found it AND the Olds pump feasibilty discovery and the Explorer brake conversion.
If anyone deserves a Hallmark portrait in the Packard haLL OF Fame it is Eric. At this point, attempts to defend the BTV are tantamount to defending COrvairs, Vega engines, Firestone tires on Ford Explorers, Toyota throttle controls ..... etc. Beyond any shadow of doubt, the BTV has gone from ridiculous to sublime to become completely absurd.

If you understood how Mercedes used the Treadle Vac in their cars you'd realize that the statement is correct.
Well, please explain it then. The BTV we have all been talking about can still apply hydraulic pressure with no vacuum present. How did Mercedes application differ?

I just read the MB post and it states:
Through Chassis Number 5500353 a Bendix Treadle-Vac booster unit was fitted, with a 5-1/4 inch vacuum cylinder which was integral with the master cylinder, providing the startling experience of no brakes at all if the booster unit failed. As long as it is integral with the master cylinder (which is the way all BTVs that i have seen are built) how does MBs application of it differ from Packard Olds or Buick?

Keith, thanks.
Randy, read the article, it explains exactly how the Mercedes system differed from the Packard version. Let me give you that link again: 300SL Quote: Two Master cylinders were placed in front of the brake pedal separately serve the front and rear brakes. The fluid reservoir is positioned directly above the master cylinders...... If the BTV is so safe and never suffered from failure in the '50s, WHY did Mercedes Benz replace it with something else in 1955?????

Since obviously some folks have had BTV fail on them, while others have been driving their's for years, and even putting significant mileage on them, why dont we focus on the exact reason while the ones that failed did so.
I think it's well known how several people feel about them, so derailing every BTV thread in a doom and gloom session is just getting old and doesn't serve any positive benefit to getting the issue addressed. If you want to carry on a conversation about alternatives to the BTV, then that is what the Modification forum is for. Frankly we are running out of snow to piss in, and the website's snow making machine is broken.

Kevin, it isn't a matter of "doom and gloom", it's a documented fact across several makes of automobiles that have used this particular unit. Ignoring the facts will not make them go away.

And once again that has been brought up repetitively for the last 4 years across these forums.
GM who put the BTVs in Millions of vehicles didn't have a mass problem with them. I believe there is a problem that can occur in these units and cause a problem. The purpose of this thread is to come up with the reason for the those isolated failures. Yes isolated. Cause we are not hearing from a majority of people saying there units failed, we are hearing "loudlly" from a small minority of people relevant to the population of BTV equipped vehicles owners out there. So lets stop pissing in the wind and move on to finding the reason.

If people can keep the discussion mature and professional, I like hearing both sides of the argument. However, some of the discussions reminds me of Jack Nicholson saying "Honey I'm home".
