<p>Twin brake force control units, for a two circuit brake system are known in which the initial control force is changeable dependent on the vehicle load. The control force is distributed to the control pistons by a lever. Due to tolerances and erosion of the individual elements considerable differences in pressure in both brake circuits may occur. This is overcome according to the present invention by providing a lever which directly operates upon both control pistons and which is rotatable about an axis perpendicular to the shifting movement of the control pistons and which is additionally rotatable about its longitudinal axis. This double rotation of the lever is accomplished by supporting the lever in a spherical joint.</p> |
