A hydraulic brake system for a work machine is disclosed. The hydraulic brake system comprises a first hydraulic circuit including a first pump for providing fluid flow to a cooling system, a second hydraulic circuit including a second pump for providing fluid flow to a plurality of hydraulic systems, a valve configured to allow fluid flow from the second hydraulic circuit to the first hydraulic circuit, and a control unit configured to control the valve based on real-time braking requirements and signals received from a plurality of sensors disposed on the work machine.

Via a method for venting at least one brake channel in a brake circuit of a compressed-air brake system of a vehicle, the brake channel can be vented. The compressed-air brake system has a brake pressure modulator that includes switchable valves for a control pressure. The brake system has an electronic control device interacting with the modulator. The modulator has, for each brake channel, at least one relay valve via which, firstly, a quantity of air can be introduced into at least one brake cylinder for actuating the brake and, secondly, the brake cylinder can be vented. During the venting operation, an adjustment to a setpoint pressure target is implemented. A setpoint pressure gradient during the venting operation is changed, in a manner dependent upon the pressure in the brake cylinder and on the operating state of the vehicle, in accordance with an algorithm stored in the control unit.

A computer system has processing circuitry to obtain vehicle combination load information of at least one of a vehicle and a trailer of a vehicle combination, the vehicle and the trailer being connected to each other; and determine a type of connection between the vehicle and the trailer based on said vehicle combination load information.
