What can happen if a truck and trailer are continuously braked with the service brakes on a long downhill slope?

The wheel brakes heat up to such an extent that the braking action is dangerously reduced

The air supply to the brake system is not supplemented

The action of the retarder is reduced

Here is Our AI Assistant's Explanation

When driving a truck with a trailer down a long downhill slope and relying continuously on the service brakes, the wheel brakes can overheat. This overheating reduces their effectiveness, which is dangerous because it means the vehicle may not slow down as needed. This is why drivers are advised to use engine braking or retarder systems to help control speed and avoid constant use of the service brakes, preventing brake fade and maintaining safe braking performance.
