Are You Familiar with the Braking Systems on a Heavy Truck?

Are you thinking of applying to get a heavy rigid licence? You may recognise some opportunities to earn some money by having such a licence, as you can get involved in the distribution trade that is particularly busy at the moment. Yet you will need to learn how to drive such a vehicle as the technique involved is very different to that of a typical car or ute. What do you need to know about the braking capability, as one example?

Air Brake Systems  

Many larger vehicles like this have air brakes. These rely on an engine-driven compressor to replenish the air in the brake reservoir tanks at any given time. Consequently, you must always rely on the engine if this braking system is going to work as intended. For example, don't think about coasting downhill while relying on your foot brake to control the speed, as you might in a car or small truck. In this case, there may not be sufficient air in the system to operate the brakes effectively, and you may not be able to stop at all.

The Potential for Failure

You need to be particularly aware of the potential for brake fade if your vehicle is fitted with conventional brakes. This can happen if you drive through deep water or keep your foot on the brake pedal for long periods of time. Some drivers tend to do this if they are driving through particularly hilly terrain, but issues can definitely arise. The brake fluid will heat up to such a point that it may begin to boil. This will lead to a loss in hydraulic pressure and poor performance. In this case, it's important to change down to a lower gear. Try to do this before you reach any decline, or stop for a period of time before continuing with your journey.

Other Braking Systems

Many heavy vehicles are fitted with an axillary break that is also called a "retarder." It's a component fitted within the vehicle's drivetrain and can help slow down the truck when activated.

Be Prepared

Heavy vehicle drivers should never rely on their conventional "service" brakes alone and should always have a backup plan in place. Use the engine to slow a vehicle down, especially when descending a long hill.

Your Best Approach

As you can see, there are many additional factors to consider when trying to operate a heavy rigid vehicle. So, before you apply for your licence, you should enrol in a training school, which will help you to learn what you need to know before you take the test.
