Congratulations Tim!
I know what it means to finally hear all 8 cylinders on the Packard V8 finally firing in harmony. Our engines have a sound all their own. Keep up the good work!

Thanks, Jim. Before heading out to work this morning, I first went to the garage and turned over the Patrician. It again fired right up andjust sat there purring. In less than 2 minutes, the oil pressure was pegged right at the mid-point of the guage. At least I can be cool while re-building that Bendix Treadle-Vac master cylinder.
I'm really getting pumped to put the wheels back on it and seeing it move, and stop, on its own for the first time in what I am sure is quire a few years.

Well gang, I'm still working on rebuilding the Bendix Treadlevac master cylinder for the Patrician and I'm finding that it sure isn't as easy as Ross makes one believe when reading his blog. Then again, Ross is much more experienced than am I at things mechanical and probably has all of the necessary tools at his fingertips.
Just to keep you all abreast of what has been going on, I'm currently dis-assembling two Bendix Treadlevac master cylinders for re-building. The one out of the Four Hundred and a spare I picked up some time ago for re-building. I have a third which came out of the Patrician, but it is the worst of the three from my amateur eyes and I haven't tried to dis-assemble that one yet. The latest major holdup has been the lack of a 1 1/8 inch socket to remove the check valves from the master cylinder itself. I picked that up at Sears on Friday and as my bicep tendonitis gets better, I'll be working its magic on the two master cylinders. The two vacuum cylinders are disassembled, but I have not yet disassembled the vacuum pistons. As I work with the Patrician and the Four Hundred, I'm coming to the conclusion that the Patrician is the mechanically more sound of the two vehicles, while the Four Hundred is cosmetically the more appealing at present. The Patrician's engine runs much smoother than does the Four Hundred's and the Patrician's brake system, once the master is finished, will have been completely rebuilt. That's about all the progress to report at this time. If the re-building of the Bendix Treadlevac system proves too much for me, I may just send the Patrician's original master cylinder to Fred Kanter with a cheque and have it professionally rebuilt. Stay tuned to see which path the Patrician travels down.

As I finish my on-again, off-again project of rebuilding the Patrician's Bendix Treadle-vac master cylinder, I've had some conflicting suggestions as to what type of brake fluid I should use when I install the re-built master and bleed the system. A friend of mine who has several vintage autos, but no Packards, sadly, recommended that I use DOT5 fliud because it has a silicon base and does not retain moisture.
To those of you who may be new to my blog, I had to completely re-build the Patrician's brake system because the Yahooo who had it before me screwed up the rear wheels like no one's business. So, the Patrician has all new brake lines, wheel cylinders, and now a re-built master cylinder. Mixing old and new brake fluids is not a problem with this vehicle. I am leaning towards using the DOT5 brake fluid remembering some of the rusted out brake lines that I replaced when re-building the brake system. If the DOT5 silicon fliud keeps out more moisture - so much the better. However, I thought I would run this past some more experienced re-builders before I do something stupid that I have to spend countless hours fixing.

DOT5 or any other fluid doesn't keep the moisture from entering, that happens as air (containing moisture) enters the fluid reservoir thru the cap vent as the fluid level drops when the brakes are applied. The same air (without some of the moisture) is then expelled as the brakes are released. The advantage to DOT5 is that it doesn't "attract" the moisture as DOT 3 and DOT4 do. Also DOT5 eliminates whatever moisture enters from becoming co-mixed with the fluid, and thus is far kinder to wheel cylinders and masters. With DOT5 the moisture accumulation (which will certainly be less than with conventional fluid) remains as a separate phase in the lowest point in the system unless you flush regularly, just as you should do with conventional brake fluid. DOT5 has some nice advantages, especially for museum-type or rarely used cars but does not eliminate the entry of moisture into the system.

Some suppliers do not like silicone fluid. I had used it in my car with BTV and it seemed to work. Had planned to use it with all the playing with different masters I've been doing. One thing I feel and while it is purely subjective, to me it seems the silicone fluid is slightly thinner than the DOT 3 or 4.
My plans were changed when this little missive from MPB appeared with some of the components I bought. No reasons for the dislike are given. Attach file:  (13.27 KB)

Howard, along those lines and I don't know if it's still the case but at least 2 of the major Bendix TreadleVac rebuilders gave the same warning in the past. I've used DOT5 with satisfaction years ago in a 48 Custom 8 which saw only occasional use, but when I did the brakes in the 56 Carib in went with DOT4 and likewise no problems over past dozen years though I do flush and refill every 3 or 4 years. The Carib sees plenty of driving and the brake components probably get hot enough to drive out at least some of the moisture.

I've been running DOT 5 (silicone) since 1997 and 27k+ miles in my 56 Executive. First 7 years with BTV and remainder of time with a modern conversion power unit.
NO problems. The previous owner had gone thru the brake system back in the 90's with alot of NEW parts from either Kanter or MErit. He used the dot5 so i have not bothered to revert back to the dot 3 nor have i been able to find any reason over the last 15+ years to go back to dot3. Good reasons to stay with Dot 5 tho.
