What is the purpose of retarders in a vehicle?

The purpose of retarders in a vehicle is to slow the vehicle down and reduce brake usage. Retarders function by providing additional braking force without relying solely on the conventional brakes, which helps to decrease wear and tear on the braking system. This is particularly useful in heavy vehicles, such as trucks, where maintaining control and extending the life of brake components is crucial. By using a retarder, drivers can manage vehicle speed more effectively, especially on descents or during prolonged braking situations, allowing for a safer driving experience. The additional braking power helps maintain control without overheating the brake system, thereby enhancing overall safety and efficiency.
