The invention relates to a parking brake, especially for a motor vehicle. Said parking brake (1) comprises a cable traction device in order to actuate the brake and opposite cable deflection by means of at least two deflection rollers (6, 7, 19, 20). The deflection rollers (6, 7, 19, 20) are arranged in such a manner that the connection line can be rotated between the rotational axis of at least two deflection rollers (7, 8, 19, 20) with respect to the drive main axis (18). As a result, a parking brake which is simple to construct and which requires a minimum amount of space is produced. Said parking brake can tighten two brake cables with an essentially equal force in an opposite direction.
