Abstract
A motor vehicle brake system having a hydraulic cable, via which a wheel brake module can be pressurized by a brake medium using brake pressure from a brake cylinder and to which a low pressure accumulator is connected for temporarily receiving excess brake medium, wherein the low pressure accumulator is connected to the hydraulic cable via a backflow line and a return pump interposed in the return line in order to return temporarily stored brake medium, the return pump being cyclically actuated for adjusting the pump capacity such that an activation occurs within each braking cycle during a portion of pump cycles that corresponds to the pump capacity, is intended to provide particularly high operational safety while also providing a comfortable pedal sensation.
