COnversions or no conversions, i'd like to know what's happening to the Treadle Vacs causing them to fail.

IIRC During the mid 50's Chevy used some kind of a goofy ass power brake unit that mounted high on the fender skirt. Not sure how it worked. I think 2wo MC's were used. One on the firewall that fed a slave on the power booster that then pushed another MC. IIRC it looked just like the Bendix TV unit on the Packard except it was mounted remotely.
My point, is that it was MOUNTED HIGH.

I don't recall doing any work on Keith's Honda power brake conversion other than a few phone conversations; I'll give him full credit for that one
I've never actually seen Eric's Ford power brake conversion, but it sounds like a good one. If he hasn't already done so and has some pictures, maybe Eric should write up a "How-to" and post it under projects on this site. Also, as another varient, do not forget Paul's Lincoln-based power brake and disc brake conversion on his 1956 Executive:http://www.1956packardpanther.com/PaulPowerBrakes.html So, there are plenty of ways to go if one wants to replace the BTV on any 1952-56 Packard that has one.

Let's not loose sight of what started this thread in the first place, NOT a hydraulic failure or a boost failure, but a failure of the pedal to return to the rest position.

I mite do that Owen. Thanks for the numbers. My preference would be to let the service providers explain it to ALL of us instead of me acting as a liazon. No matter how many questions i ask them there will always be a question that someone else has that i can't think of.
Why not let the service providers answer questions here at this forum where everyone can join into the correspondence. It's more timely, less schedule restrictive, and gives everyone involved time to digest the info.

That would be my preference as well, but let's face it, these guys are running businesses, tending to payrolls, suppliers, customers, families, kids in college and all that, so they probably don't have the time or inclination to sit for a couple of hours and see what websites might be looking for their input. I only suggest Ed Strain because of his sterling reputation with TV units. I personally believe some TV problems are the result of (a) using 50 year old rebuild kits with dried out old parts and not always including the parts we might need, and (b) either using the corner brake shop as a rebuilder, or doing it yourself without proper knowledge. But hopefully we await what you find out from the folks who do it for a living.

See FIrst post of this recent thread at AACA:
http://forums.aaca.org/ubbthreads.php/topics/579873/56_BRAKE_PEDAL_ISSUES#Post579873 Sounds like a hydraulic problem to me. The failure of the pedal to return is a secondary problem.

Different poster, different problem I guess.
I think we've flogged this one enough until such time as we come up with some new information.

You wrote: Quote: One of the rebuilders stated that a good rebuild could not be accomplished without "extensive machining" of the MC which his shop did but others didn't do & just changed the seals. That was a guaranteed failure in short order was his feeling. IMHO, unless he is retrofitting some sort of alternate parts, that rebuilder is full of it. There is NO need to machine (or sleeve) a BTV master cylinder. The plunger moves fluid by simple displacement, sliding through a stationary seal. The OE hard-chrome plated plunger will, however, become pitted over time and work like a cheese-grater on the seal. A new plunger can be fabricated locally. A badly corroded master cylinder housing should be replaced.
