What Kind of Brakes Are on Semi-Truck Trailers?

Semi-truck trailers have come a long way in terms of technological advancement. They are now equipped with a variety of safety features, including brakes, to ensure the safety of drivers and other motorists on the road. There are two main types of brakes that are used on semi-truck trailers: air brakes and hydraulic brakes.

Air Brakes – Air brake systems use the compressed air from the truck’s engine to apply pressure to a set of brakes that are mounted to the trailer’s axle. The pressure is then transferred to the wheels, causing them to slow down or stop.

Air brake systems are generally considered to be more reliable than hydraulic brake systems because they require less maintenance and can be less prone to malfunctions.

Hydraulic Brakes – Hydraulic brake systems use fluid pressure to apply force to a set of brakes mounted on the trailer’s axle. This force is then transferred to the wheels, causing them to slow down or stop. Hydraulic brakes are not as reliable as air brakes but they can be easier and cheaper to repair if something does go wrong.

Both types of brake systems have their own advantages and disadvantages so it is important for truckers and fleet owners alike to understand which type of system is best suited for their needs.

Overall, semi-truck trailers have come a long way in terms of safety features, thanks in large part due their advanced braking systems. Whether it’s an air or hydraulic system, it is important for truckers and fleet owners alike to understand which type of system best suits their needs in order keep drivers safe on the road.

Conclusion:

In conclusion, semi-truck trailers typically use either air or hydraulic brakes as part of their safety features. Both types have advantages and disadvantages that should be taken into account when deciding which type best suits your needs. No matter which type you choose, understanding how these braking systems work can help keep drivers safe on the road.
