    This document provides information about the wet brake system on a vehicle. It contains diagrams and descriptions of the key components. The wet brake system uses full hydraulic wet-disc brakes with an operating pressure of 6MPa. It has a charging valve that opens at 12.3MPa and cuts at 15MPa. Low pressure switches detect pressures of 10MPa or less for the service brakes. The nitrogen accumulators maintain a pre-pressure of 5.5±0.05MPa. The parking brake and clutch cut-off engages at low pressure to prevent vehicle movement. Alarms activate at pressures below 11MPa for the service brakes and parking brakes. Power is cut
