The present invention relates to a method and a device for monitoring a brake system for motor vehicles equipped with an electronic controlling and regulating unit, as well as a hydraulic pressure accumulator that is used as an auxiliary pressure source and subdivided by a media-separating element into two chambers, the first chamber being filled with a gas and the second chamber being filled with a liquid pressure medium. To conduct a reliable monitoring of the pressure accumulator, the invention provides that the number of the partial strokes of the media-separating element is detected. To this end, brake actuations are weighted and counted according to their duration and intensity. When the sum of the weighting factors reaches a predetermined number, a warning indicates an imminent damage to the media-separating element. This renders it possible to use a less costly and less sensitive media-separating element, which obviates the need for extensive protective measures against mechanical loads.
