Abstract

In a method for adjusting the clamping force exerted by a parking brake, which force is applied by an electric-motor braking apparatus and by a hydraulic braking apparatus, the hydraulic inlet pressure generated by the driver and existing in the hydraulic braking apparatus is utilized to generate a hydraulic clamping force; and for the case in which the hydraulic clamping force is not sufficient to reach a target clamping force, an electric clamping force is generated in supplementary fashion.
