What does the air pressure gauge indicate?

The air pressure gauge is specifically designed to provide information about the current pressure level in the air brake system of a vehicle. This is crucial for the safe operation of vehicles equipped with air brakes, as it indicates whether the system is functioning properly and whether there is sufficient air pressure to engage the brakes effectively.

Maintaining the appropriate air pressure is essential for the safe stopping of the vehicle, as inadequate pressure can lead to brake failure. The gauge typically shows measurements in pounds per square inch (PSI), allowing the driver to monitor the status of the brake system continuously. Proper understanding and monitoring of this gauge enable drivers to respond promptly to any issues related to air pressure, ensuring functional and safe braking performance.
