Trailers are capable of towing from boats to cargo, and therefore they are therefore critical for both new and experienced operators. However, being aware of whether you own/need a braked or an unbraked trailer is the difference between driving efficiency and safety.
What is a Braked Trailer?
A braked trailer has an independent braking system. A braked trailer also comprises a mechanical or electric system for engaging their brakes when the tow vehicle is braking. The overrun braking system is the most common, where it acts automatically since the towing vehicle is slowing down. There are electric brake controllers fitted to some of the more expensive braked trailers with more control.
One of the largest advantages of braked trailers is that they can pull more weight in the manner of how heavy they are. Depending on regulations in a region, trailers over some weight threshold specified—typically 750 kilograms (1,650 pounds)—by law have brakes installed on them. This is because the secondary braking system is lighter on the towing vehicle and safer, especially down a gradient or in brake use as an emergency brake. For heavier loads like machinery, campers, or boats, a braked trailer would likely be the best option.
What Is an Unbraked Trailer?
Unbraked trailers, by the name itself, lack any braking system of their own. They rely on the brakes of the towing vehicle to bring the vehicle and trailer to a slow. They are lighter and simpler in design, so easier to use and maintain.
The lack of a braking system limits unbraked trailers to a maximum weight. Jurisdictional limits vary, but typically they are less than 750 kilograms (1,650 pounds) loaded. That is why unbraked trailers are appropriate for lighter loads, e.g., small utility trailers, light domestic service, or garden refuse collection.
Though convenient and inexpensive, unbraked trailers may be overloaded, causing excessive stress on the brakes of the towing vehicle and posing a risk.
Differences Between Braked and Unbraked Trailers
The largest distinction between unbraked and braked trailers from the likes of FWR Australia is within the braking system. Braked trailers have an independent braking system, offering additional safety and the ability to tow additional weight, while unbraked trailers are dependent on the towing vehicle’s brakes and are limited to lighter loads.
Weight capacity is also a consideration. Braked trailers can tow a much greater weight capacity and are therefore ideal for commercial or recreational use with heavier towing. Unbraked trailers are lighter, more agile, and safer for light-scale uses but less flexible.
And last but not least, safety. Braked trailers are safer than unbraked trailers if it becomes necessary to make an emergency stop, where safe and prompt braking is required. Unbraked trailers can cause extra wear on the brakes of the towing vehicle, increase the likelihood of becoming unstable while descending a hill or with heavy braking, and affect control.
Choosing the Right Trailer for Your Application
It is advisable to understand your haulage requirements and payload capacity in choosing between a braked or unbraked trailer. A braked trailer will be worth spending money on in case of heavy use, longer distances, or commercial use. However, for lighter and periodic use, an unbraked trailer can prove to be as good.
