ABSTRACT:
An arrangement for ensuring the functioning of a brake configuration for a vehicle with a multiplicity of wheels which are arranged on a front axle and at least one rear axle and which support the vehicle. The brake configuration incorporates at least two brake devices, each to act upon one of the wheels, and a brake control with which the brake devices can be activated with a total brake action. A memory stores at least one value of a parameter for the brake devices. The parameter relates to at least one previous braking operation performed by the respective brake device. A control unit distributes the brake action to the brake devices, taking into account the value of the parameter of the respective brake devices when the brake control is actuated. The brake devices are disc brakes. The value of the parameter indicates to what extent a film has accumulated on the brake lining surfaces which come into contact with the respective discs, which film reduces the friction between discs and brake linings at least incipiently. If the value indicates that such a film has formed, the whole or a major portion of the brake action called for by the driver, i.e. the total brake action, is distributed to the disc brakes whose value of the parameter indicates the presence of such a film.
