What Are the Brakes Called on a Semi-Truck?

Semi-trucks are large vehicles that are used for transporting goods and materials over long distances. As with any vehicle, semi-trucks must have brakes in order to stop safely. The brakes on a semi-truck are very different from those of a regular passenger car, and they are known as air brakes.

The air brakes on a semi-truck consist of several components that work together to slow down the vehicle. The main components of the system include an air compressor, an air storage tank, brake chambers, and brake drums.

The compressor is responsible for producing the compressed air that is used to activate the braking system. This compressed air is sent to the storage tank and then released into the brake chambers when the driver presses on the brake pedal.

Once the compressed air is released into the brake chambers, it forces pistons inside them to move outward. This movement causes shoes inside each chamber to press against corresponding brake drums, which then cause friction and slow down the wheels of the truck.

The brakes on a semi-truck are commonly referred to as air brakes, due to their reliance on compressed air in order to operate correctly. Air brakes require regular maintenance in order to function properly, as they can become worn down over time from frequent use. It is important for truck drivers to be aware of how their braking system works in order to ensure their safety while out on the road.

In conclusion, the brakes on a semi-truck are called air brakes. They rely on a complex system of components that work together using compressed air in order to slow down or stop the vehicle when needed. It is important for truck drivers to understand how this system works and keep it properly maintained in order for it remain safe and reliable while out on the road.
