Why you need to add a hydrodynamic retarder

Hydraulic retarders can fully meet the auxiliary braking needs of vehicles and can also handle 80% of the overall braking tasks during vehicle operation. On long downhill sections, they can prevent the main brakes from malfunctioning due to overheating, thus avoiding traffic accidents and significantly improving the safety of vehicle operation.Hydraulic retarders can fully meet the auxiliary braking needs of vehicles and can also handle 80% of the overall braking tasks during vehicle operation.

In addition, hydraulic retarders are also applicable in everyday situations such as waiting for traffic lights, or in traffic jams where the vehicle needs to decelerate. They can reduce the frequency of brake pedal usage and extend the lifespan of brake pads.

As is well known, disc brakes have higher braking efficiency compared to drum brakes. However, disc brakes cannot be water-cooled during high temperatures; if water is applied, the brake disc may crack. This means that the traditional installation of water cooling on heavy-duty vehicles with disc brakes becomes impractical. On long downhill sections, disc brakes experience severe thermal decay, leading to a reduction in braking force. At this point, vehicle braking becomes extremely dangerous. Therefore, vehicles equipped with disc brakes are better off installing hydraulic retarders to ensure braking safety. 

After installing a hydraulic retarder and completely replacing the water cooling system, it is possible to save the installation and water filling costs. Moreover, the need for frequent visits to water filling stations is reduced, improving operational efficiency. Additionally, as the frequency of brake application is decreased, it significantly extends the lifespan of tires and brake pads, reducing the costs associated with tire and brake pad replacement. 

Furthermore, eliminating the water tank for cooling will reduce the overall vehicle weight by nearly 1 ton. This allows the vehicle to carry more cargo, leading to a substantial increase in income.

Certainly, while money is important, safety is even more crucial. For vehicle owners who have the capability and need for installing a retarder, it is highly advisable to equip the vehicle with a hydraulic retarder.
