Question: 1 / 400

How does a driver check for air brake system leaks while performing the pre-trip inspection?

By checking the brake fluid level

By looking for wear on tires

Listen for hissing sounds or perform a visual check on hoses and connections

The correct choice highlights the importance of both auditory and visual checks in the process of identifying air brake system leaks. During a pre-trip inspection, a driver should listen for hissing sounds that may indicate escaping air from the system, which is a key sign of a leak. Additionally, performing a visual inspection of hoses and connections is crucial, as it allows the driver to spot any signs of deterioration, damage, or looseness that could lead to air loss.

By incorporating both listening and visual checks, the driver can more effectively ensure that the air brake system is functioning properly before starting a trip. This practice is essential for maintaining both vehicle safety and operational efficiency, as air leaks can significantly impede braking performance.
