A brake system, method for controlling the brake system and a mine vehicle having the same are provided. The brake system of the mine vehicle includes spring activated and hydraulically released brake assemblies in connection with wheels of the vehicle. The brake assemblies have hydraulic release actuators, which are pressurized for releasing the brakes. During normal operation, the release actuators are pressurized by a main brake circuit and are controlled by a brake controller. A separate release circuit and pressure source may be activated for releasing the brakes when the vehicle is disabled. The system further includes an override device for selectively depressurizing the release actuators during towing.
