Abstract

A method for operating a parking brake with an electromotively driven parking brake mechanism includes applying the parking brake by the electric motor, switching off the electric motor in the state in which the parking brake is applied, switching on the electric motor after a prespecified time and reapplying the parking brake mechanism in the brake application direction. During the brake reapplication operation, an electrical variable of the electric motor is determined and compared with a reference value. The brake reapplication process is continued or terminated depending on whether the electrical variable, or a variable derived therefrom, is smaller or greater than the reference value.
