Apparatus for a lever (6) for controlling a parking brake including brake units and an electrically driven tightening means for applying or releasing a braking force on the said brake units. Characteristic of the invention is that a means is arranged to detect the position of the lever and produce control signals to a first electric motor (12) for generating a brake force corresponding to the position of the lever. The lever can be adjusted manually. Further there is a second electric motor (49) intended to automatically control the lever (6) depending on incoming control signals. In the fully applied position the lever (6) is locked against manual adjustment. L'invention porte sur un appareil équipant un levier (6) destiné à commander un frein à main. L'appareil comprend des blocs freins et un moyen de serrage électrique pour appliquer ou libérer une force de freinage sur lesdits blocs freins. L'invention se caractérise en ce qu'un moyen est arrangé pour détecter la position du levier et transmettre des signaux de commande à un premier moteur électrique (12) afin de générer une force de freinage correspondant à la position du levier, lequel peut être réglé manuellement. En outre, un deuxième moteur électrique (49) est destiné à commander automatiquement le levier (6) en fonction des signaux de commande entrant. En position d'application intégrale, le levier (6) est verrouillé, ce qui interdit tout réglage manuel.
