ABSTRACT:
Dual circuit brake force control units are known in which the initial preloading force is changeable dependent on the vehicle load. The preloading force is distributed to the control pistons by means of a lever. Due to the tolerances and erosion of the individual elements, considerable differences in pressure in both brake circuits may occur. Therefore, according to the present invention a lever is provided which directly acts on both control pistons and which is rotatable around an axis parallel to the direction of displacement of the control pistons and additionally around the longitudinal axis of the lever. The lever is in interaction with its housing mount at one support point at least and at two support points at the most with the support point or support points being located at least approximately in the longitudinal axis of the lever.
