Abstract: A vehicle brake system includes a first main cylinder with a first main cylinder connection and a first actuating device with a first actuating connection. The first main cylinder connection is in flow-connection to the first actuating connection, and the first actuating device is operable with the first main cylinder. A first brake circuit is provided between a pump and a first wheel cylinder, where the pump in the first brake circuit is operable to generate pressure and move a fluid within the first brake circuit. A first valve device is provided in the first brake circuit where the first valve device is movable between a first configuration in which a flow connection is produced between the pump and the first wheel cylinder, and a second configuration in which a flow connection between the pump and the first wheel cylinder is prevented.

Abstract: An agricultural vehicle-trailer-combination includes a traction vehicle including an engine and at least one ground engagement mechanism. A trailer is coupled to the traction vehicle. A service brake connected to the at least one ground engagement mechanism. The combination includes a sensor and a control unit disposed in communication with the sensor, wherein a slip or a slip gradient on the ground engagement mechanism is sensed between the ground engagement mechanism and the ground surface. A trailer brake disposed on the trailer is adjustably controlled by the control unit. The trailer brake is adjustably controlled when the service brake of the traction vehicle is actuated, and the trailer is braked by the trailer brake as a function of the slip or the slip gradient when the slip reaches or exceeds a predeterminable slip braking value or the slip gradient reaches a predeterminable slip gradient braking interval.
