What could be a potential cause of air leaks in the system?

Air leaks in the braking system can significantly impair its performance and compromise safety. Loose fittings or connections within the air brake system can create gaps where air escapes, leading to a drop in air pressure. This makes it difficult for the system to maintain the necessary pressure for effective braking. Regular inspections of fittings and connections are crucial in ensuring they are properly tightened and sealed to prevent leaks.

While underinflated tires, dirt on brake pads, and faulty electrical connections can affect vehicle performance, they are not direct causes of air leaks in the brake system. Underinflated tires can lead to reduced traction and increased wear, dirt on brake pads primarily affects braking efficiency and wear, and electrical connections relate more to the functionality of lights and sensors rather than the integrity of the air brake system itself.
