Role of Part 3406905 Flexible Hose in Engine Systems

The part 3406905 Flexible Hose is integral to the efficient operation of various engine systems, particularly in the context of brake and engine brake applications.

In the Brake System, the flexible hose facilitates the transfer of hydraulic fluid from the master cylinder to the brake calipers or wheel cylinders. This transfer is essential for the application of braking force, ensuring that the vehicle can decelerate or stop as required. The flexibility of the hose allows it to accommodate the movement and vibrations inherent in the vehicle’s operation, maintaining a consistent flow of hydraulic fluid without compromising the integrity of the brake system.

For the Engine Brake 411 D 12 / 24 V Kit and the Engine Brake 411 E Kit, the flexible hose plays a significant role in the modulation of engine braking forces. These kits are designed to enhance the vehicle’s braking capabilities by utilizing engine compression to assist in deceleration. The flexible hose in these systems ensures that the necessary fluids or gases are delivered efficiently to the components that modulate the engine brake, allowing for precise control over the braking effect. This is particularly important in heavy-duty vehicles where engine braking is a key safety feature.

In the broader context of the Engine Brake Kit, the flexible hose contributes to the overall reliability and performance of the engine braking system. By providing a durable and flexible connection between various components, it ensures that the system can operate under a wide range of conditions without failure. This is especially important in applications where the engine brake is used frequently, such as in commercial trucking or off-road vehicles.

Conclusion

Overall, the part 3406905 Flexible Hose is a vital component in ensuring the smooth and efficient operation of brake and engine brake systems, contributing to the safety and performance of the vehicle.
