Abstract

A vehicle brake system and method for operating same, having a master brake cylinder, a brake medium reservoir, and a first brake circuit, connected via a reservoir line to the brake reservoir, having at least one first wheel brake cylinder, a first wheel inlet valve associated with the first brake cylinder, a first pump, by which a first brake medium volume is pumpable from the reservoir line through the open first wheel inlet valve into the first brake cylinder, a continuously adjustable first wheel outlet valve, by which a first brake medium displacement from the first cylinder into the brake reservoir is controllable, and a connecting line having a spring-loaded non-return valve, via which a delivery side of the first pump is connected to the brake reservoir, a brake medium displacement from the brake reservoir to the delivery side of the first pump being prevented by the spring-loaded non-return valve.
