The present invention relates to a parking brake including a lever (3) coupled to a brake wire (9) included in the brake system. Characteristic of the invention is that the lever (3) is arranged to work in two steps to achieve the desired braking power. In the first step the lever is arranged to make a translational movement for taking up wire slack in the brake system, while in the second step the lever is arranged to execute a rotation whereby the force transmission to the wire (9) takes place at a higher ratio than in the first step.
