I owned a 56 400 in the early sixties. The seal between the hydraulic cylinder and the vacuum canister failed. I bought a kit and rebuilt it myself. It never failed again. Memory says that the kit contained a new compensating valve and spring. I purchased a 56 400 in 1972 and have had it rebuilt by a professional rebuilder. He replaces all the components that could fail including the small spring that causes the compensating valve to close. I have never heard one of the complainants of the TV system determine WHY their unit failed. I would like to hear one of them say they tore the unit down and discovered that A or B or C was the component that failed. And then verify that they had replaced that component when they rebuilt it. That small 50-year old spring that has been sitting in water-contaminated brake fluid for 50 years has to be replaced. If not, it will fail. When rebuilding any system like the TV, you must replace all such components.
