The invention concerns a fail-safe brake system for use in combination with a service brake system of a vehicle. The fail-safe brake system includes a high pressure fluid source for supplying fluid to a protection valve though an inlet line to the valve. The inlet line splits into a number of independent circuits which include braking means for braking the vehicle when the system is activated though a network of lines running from the protection valve to the braking means. The system further includes control valves for controlling the activation and deactivation of the fail-safe brake system by controlling the flow of fluid in the circuits. By controlling the fluid flow in the circuits, the activation and deactivation of the braking means are controlled. The fail-safe brake system may be activated and deactivated independently of the service brake system of the vehicle, thereby allowing the braking means to function independently of the service brakes of the vehicle. The invention also concerns a method of activating and deactivating the failsafe brake system. |
