Should You Retrofit Retarders to Your Trucking Fleet?

If you run a fleet of trucks, you must ensure that they are well maintained with good-quality Hino truck parts so that you avoid the risk of breakdown and reach maximum productivity. You must also ensure that each vehicle is safe and fit for the purpose, especially when they are carrying a full payload or driving across some challenging terrain. This is why you should ensure that all of your vehicles are fitted with a retarder and that it is configured correctly. Why is this such an important component in the trucking industry today?

Additional Braking

Generally speaking, a retarder is a device that is quite independent of the vehicle's braking system but is designed to create an auxiliary force to slow down the driving wheels in certain circumstances. In fact, a fitted retarder must be able to slow down the vehicle when it is driving downhill by itself, without the help of the service, parking or emergency brakes.

This type of solution is finding its way into the trucking industry across Australia and is in widespread use in other parts of the world. It is fitted within the driveline of the vehicle and acts directly on the road wheels, while it can be activated independently by a hand-operated lever or by switches that are fitted to the clutch and accelerator.

How It Works

Essentially, the retarder is made up of several electromagnetic coils, and current alternates between two rotors and a stator. This will slow down the movement of the rotor, and in turn, force the vehicle to decelerate. While many new vehicles are now being equipped with this type of retarder as standard, the good news is that they can be retrofitted to any truck, no matter its size.


If you live in a part of the country where the terrain can be quite challenging, this type of solution is ideal. It can eliminate the risks associated with excess use or overheating and can provide a serviceable and fully operational option should an emergency situation arise.


Furthermore, a retarder can help to cut down on maintenance costs during the course of a busy year. They can reduce the costs of replacing individual brake components and can also act to regulate fuel consumption.

Taking Action

Make sure that your fleet operation is as safe as possible, and think about adding a retarder to each one of your trucks, from a safety and performance perspective.
