4. To improve the shock absorption of the trailer

The correct answer is: To provide sufficient stopping power to safely slow down or stop the trailer

The primary purpose of a trailer's braking system is to provide sufficient stopping power to safely slow down or stop the trailer. This is essential for the safe operation of any vehicle, particularly when transporting heavy loads. The braking system must effectively manage the trailer's momentum, especially in varying road conditions and at different speeds. It ensures that the trailer can stop in a controlled manner, preventing collisions and maintaining road safety for both the driver and other road users. Understanding the importance of a functioning braking system is critical for trailer technicians. They must ensure that all components, including brake pads, drums, and actuators, are in good working condition. This system is vital for preventing accidents and ensuring that regulations regarding trailer safety are met. Adequate stopping power not only helps in adhering to the laws but also contributes to the overall efficiency of transport operations, where quick and safe stops are often necessary.
