They are machined out of aluminum billet and come with all fittings and lines, and mount on cowl wall for easy access. Do not recall price.

I see it in the '55 & '56 Accessories section of the parts book. From the photo it's not clear to me if there is a siphon, and if so how it is started. If the tube was mounted at the bottom of the auxiliary reservoir in a short amount of time the fluid and air would 'change places'. Most modern cars have adopted a scheme quite similar to this accessory, namely; a visual inspection without removing a cap is the means to check the brake fluid level. Once you know the level is low then the wrenches come-out. Seems to me the same is true for the coolant level.

Here is the tubing run and fill instructions but I forget where I got it or who posted the instructions.

One thing I would wonder about is the relief port in the BTVs between the seals that is supposed to provide an air or fluid path to the reservoir if either side seal starts leaking. With this arrangement if the vacuum side had issues it could still draw fluid into the power unit since there would be no air to pull.

I installed the brake reservoir back in '92. Purchased from Max sometime before that in original box. I thought I posted the original instructions long ago.

I've found what I believe is a simple analogy to the reason Treadle Vacs fail. Consider the cooling system of any car which is supposed to have some water pump lubricant in the water or anti-freeze. If you drive the car for many years without refreshing the lubricant/anti-rust, the water pump will be prone to failure and scale will form in the block and clog the radiator causing elevated running temperature and some loss of fluid.

As years go on you keep driving it and never check the fluid level or drain and flush the system. Eventually some of the rust/scale eats up the seal, the fluid runs out and the car overheats.

Why oh why you ask should my (65 year old car) suddenly overheat without warning???? It must be that damned McCord radiator!!!

Now change that scenario to brake system and "that damned Bendix Treadle Vac".

Human nature wants to blame some inanimate object rather than take responsibility for your own negligence.

Let's think of other things that fail: manual master cylinders, wheel cylinders, unretorqued head gaskets, radiator caps, rod bearings, main bearings, starters, batteries, generators etc etc. Some fail just from age, some from use, some from not changing the oil often.

Engine oil does not deteriorate from sitting 10 years, DOT 3 brake fluid does. Be mindful of who/what you curse.

Be interesting to see what Fred's "failure analysis on it" reveals.

Hi

Used Irfanview photo software to improve the schematic and instructions for legibility.
