1. How does an air braking system in a car work?

An air braking system in a car, also known as an air-over-hydraulic braking system, works by transmitting brake actuation force from the brake pedal to the brake components using compressed air.
When the driver presses the brake pedal, air from the compressor in the engine compartment is directed into an air storage tank. This compressed air is then sent through hoses and valves to the brake chambers which are attached to the brake shoes or the brake calipers.
The brake chamber converts the air pressure into linear force on the push rod, which moves the brake shoes apart or applies hydraulic pressure on the brake calipers. This action causes the brake pads or shoes to press against the wheels, slowing the vehicle down.
The air braking system also includes other components such as the air dryer, air compressor, relay valves, brake lines, brake control valves, and brake drums or rotors.
Overall, the air braking system provides an efficient, reliable, and consistent way to stop a car, making it a popular choice in heavy-duty vehicles such as trucks and buses.
SuBy implementing these tips, you can help improve the efficiency of your air braking system, avoid costly repairs and maintenance, promote safety and enjoy better braking performance
