Abstract
In load-dependent brake valves it is customary to control the brake force as a function of the stroke of vehicular suspension springs. If the stroke of the vehicular suspension springs is not proportional to the vehicle load, there is the risk that either the empty vehicle or the full vehicle is too strongly braked. This can be avoided in that a pivotable brake lever is pivotable as a function of the stroke of the vehicular suspension springs, the pivotable brake lever comprising a first pivoting range in which a first edge of a piston of the load-dependent brake valve is supported and a second pivoting range in which a second edge of the aforesaid piston is supported. It is thereby achieved that the brake force is always proportional to the vehicle load.
