During a pre-hill inspection of a vehicle with air brakes, what checks should be performed?

• A. Ensure there are no hydraulic fluid leaks
• B. Ensure there are no audible air leaks
• C. Ensure glad hands and air lines are secure
• D. b. and c. are correct

Answer: (D)

During a pre-hill inspection of a vehicle equipped with air brakes, it is essential to ensure that the air brake system is functioning correctly and safely. The correct checks focus on the integrity of the air brake components. Audible air leaks indicate that there may be a problem within the air brake system, leading to a potential loss of pressure or malfunction of the brakes. Detecting and addressing these leaks during a pre-hill inspection is vital to ensure the vehicle's safety and reliability when navigating inclines. Additionally, ensuring that the glad hands and air lines are secure is crucial, as these components are responsible for connecting the air supply from the towing vehicle to the trailer. Loose or damaged glad hands or air lines can lead to air loss, which could result in brake failure while the vehicle is under load, particularly on a hill. Therefore, by performing checks for both audible air leaks and the security of glad hands and air lines, you are addressing critical aspects of the air brake system that contribute to safe operation, especially in the challenging conditions of hill driving. This comprehensive approach ensures that the vehicle's braking system is adequately maintained and ready for the demands of driving in hilly terrain.
