Question: 1 / 400

What indication does the supply pressure gauge provide in the air brake system?

Temperature of the air system

Amount of air pressure in the tanks

The supply pressure gauge in the air brake system specifically indicates the amount of air pressure in the tanks. This gauge is a crucial component for drivers, as it allows them to monitor the air pressure levels necessary for the safe operation of air brakes. Maintaining an adequate level of air pressure is essential for the brakes to function properly, preventing brake failure and ensuring safe stopping distances.

The air pressure in the tanks must reach a certain threshold before the brakes can effectively engage, which is why this gauge is so important. It alerts the driver to any potential issues with the air brake system, such as leaks or insufficient pressure, allowing for timely repairs and maintenance. Monitoring this gauge can prevent accidents caused by brake system malfunctions that might arise from low air pressure.
