In addition to putting the new transmission in my coach I decided to see about getting the brakes to work properly. I added a reaction arm system from Applied last fall, but I still wasn't happy with the braking. Some inspection showed the master cylinder was bottoming, so I found a rebuilt one - correct one even - at O'Rielly's. Checking the system visually, I found these two weird brass cylinders teed into two lines, the front input at the proportioning valve and the rear line leaving the valve. Made by Brake Guard Products of Spokane Washington. There was a patent number, 4,571,009 assigned to one Ed Jones, prexy of Brake Guard products. The patent claims it's a pressure vessel with some specific ratios of dimension and some claimed benefits from internal air pressure.
OK, why would I want a pressure vessel on the brake lines? Well, I looked a little further and found:

Aha! It seems Mr. Jones let his mouth overload his asshole as we say. I suspect the PPO bought into the claims of a poor man's ABS for his coach and installed them or had them installed. They are now uninstalled and the ports plugged. They're machined out of brass, at some point I'll take the broken one apart and see quite what's inside it. Its mounting nipple separated before it loosened in its tee fitting. The other one is unbroken. Both are available for a modest honorarium, or I'll keep them as souvenirs.
Mr Jones had several other patents mentioned, I didn't peruse them and thus have no feeling as to their legitimacy or lack thereof.
