Abstract

A service brake device of a vehicle, including at least one ABS pressure control valve which is controlled for slip-regulated braking by an electronic control unit, has at least one inlet valve and one outlet valve and is arranged upstream of a pressure medium actuated brake cylinder, a pressure medium line which supplies the ABS pressure control valve with pressure medium and into which a pressure controlled by a valve device arranged upstream of the ABS pressure control valve is feedable, wherein the valve device feeds a pressure derived from a reservoir pressure of a pressure medium reservoir into the pressure medium line as a function of an activation by the electronic control unit.
