Abstract: Disclosed is a method for controlling a braking system for a motor vehicle, capable of implementing a parking brake function. The system includes a disk, a brake caliper and at least one piston to exert a disk clamping force on the disk, the braking system further including an electric drive unit moving the piston relative to the caliper and a hydraulic drive unit moving the piston relative to the caliper. The method includes at least one step of exerting a disk clamping force by moving the piston, by the electric drive unit and/or the hydraulic drive unit. The method includes a step of actuating the hydraulic unit by exerting a first clamping power on the piston, followed by a step of actuating the electric unit by exerting an additional clamping power, until a total power is obtained that is high enough to lock the disk.
