A system and method configured to direct the braking energy from a high-pressure port at the motor side of a hydraulic circuit to emergency steering, braking, accumulator(s) charging, and/or various work functions. The system and method are also configured to return hydraulic fluid back to the same high-pressure port when the motor is running as a pump.

A dissymmetric braking system has at least one right wheel braking device, at least one left wheel braking device, at least one device to apply a braking action, at least one actuating device to transform the braking action into a first pressure, at least one right wheel connection, at least one left wheel connection, and at least one pressure reducing device having at least one transfer device receiving the first pressure.
