Question: 1 / 400

What is typically checked during a pre-trip inspection of an air brake system?

Air pressure gauge readings

During a pre-trip inspection of an air brake system, one of the critical components to assess is the air pressure gauge readings. The air pressure gauges indicate the level of air pressure in the braking system, which is essential for the proper functioning of air brakes. Ensuring that the gauges show adequate pressure is crucial because air brakes rely on compressed air to engage and disengage the brake system.

If the air pressure is too low, the brakes may not operate effectively, leading to potential safety hazards on the road. Thus, checking the air pressure gauge readings allows the driver to verify that the braking system is functioning correctly and is within safe operational limits before starting the journey. Ensuring that the air pressure is sufficient is a fundamental part of maintaining the reliability and safety of air brake systems.
