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.
