The invention relates to a method for operating a brake device of a motor vehicle, comprising a service brake (16) and a parking brake (14). Upon activation of a rolling brake function (S1), and achieving a full stop of the vehicle, monitoring (S2) of an actuating element occurs with regard as to whether a driver has contact with an actuating element. In order to improve the safety of the rolling brake function, the invention provides that, if the monitoring (S2) finds that the driver has no contact with the actuating element, the parking brake (14) is applied (S3), or a braking pressure (14) is controlled using the service brake (16), the braking pressure corresponding to the maximum braking pressure (S10) that can be generated by the parking brake (14), by means of an electric or electronic brake device (26) for controlling the service brake (16) and the parking brake (14). The invention further relates to a corresponding method, wherein a monitoring (S11) of the vehicle occurs with regard to a possible displacement of the vehicle, and if the monitoring shows that the vehicle has been set in motion, braking is applied (S12) to all wheels of the vehicle that are connected to service brake (16) by means of the control device (26) via the service brake (16). The invention also relates to devices that are configured accordingly.
