Emergency brake

At turning on of the emergency brake behind for the lever some kind of yoke – the balance weight is extended. Brake cables which go back to brake supports are here too suspended. The sense of the leveling yoke consists in the most uniform distribution of force to both back wheels at use of the emergency brake. At the same time easy distinctions in coefficient of friction of both brake drafts are leveled by a yoke.

Cables of the emergency brake affect back disk brakes by means of a control lever, a press bar and the adjusting mechanism as it is described in the section Back disk brakes.
