Abstract: The present invention relates to an opening mechanism (1) for at least one brake in particular a parking brake comprising an actuator (30), connected to at least one brake cable (60) and a load sensor (40) for determining the mechanical load of the at least one brake cable (60) wherein the mechanical load of the at least one brake cable (60) is determined via the actuator (30) and decoupled from the at least one brake cable (60). By the arrangement according to the present invention, a direct connection between the actuator (30) and the brake cable (60) is provided wherein the load sensor (40) does not work as a load transmission or a coupling component. This arrangement meets high security requirements even in case of a failure of the load sensor (40) since the function of the operating mechanism (1) is not affected or prevented thereby.

Abstract: A parking brake which is connected to at least two brake cables, in particular for a parking brake system of motor vehicles, comprising: an actuator with linking devices to which the at least two brake cables are coupled at linking places and an operator configured and connected to the actuator such that it can change the distance between the linking places in a controlled manner whereby a relative movement of the linking places to each other or away from each other is enabled. Preferably, the parking brake comprises a set of gears and an electric motor for generating and transmitting a rotation wherein the rotation is transformed into a linear movement by way of the actuator. The actuator includes a load sensing device for measuring the load applied to the brakes. The parking brake assures a uniform operation of the respective brakes and a comfortable control with reduced efforts for adjustment and maintenance.
