The brakes were now controlled using a hydraulic mechanism. The suspension featured synchromous springing, a suspension configuration already seen on the manufacturer's larger models and based on the Dubonnet system for which General Motors in France had purchased the license. The General Motors version, which had been further developed by Opel’s North American parent, was intended to provide a soft ride, but there was some criticism that handling and road-holding were compromised, especially when the system was applied to small light-weight cars such as the Kadett. By the end of 1937 33,402 of these first generation Kadetts had been produced.
Announced in November 1947, production of the postwar Olympia, with austere painted hubcaps, began in December 1948 and allowed a modest return to export sales in that year. In October 1948, the Kapitän came back to the Opel line-up, unchanged except for such details as the shape of the headlights and improvements in the leaf springs and dampers. Prices in 1948 were 9950 DM for the Kapitän and 6,785 DM for the Olympia (the Deutschmark having replaced the Reichsmark on 20 June 1948).
It had some crazy mechanical issues. At one point it stumbled and stalled because the carburetor had come loose from the intake manifold and I had to tighten it back down! Another time, my brother was driving it and the brakes failed. Somehow the end of the brake shoe that meets the brake cylinder piston had become worn on one side, causing the piston to slip off the end of the shoe when the brakes were applied, losing braking and squirting fluid all over.
