Low air pressure can primarily lead to which of the following?

Low air pressure in a braking system can significantly impair the effectiveness of air brakes, leading to a loss of braking power. The air brake system relies on a combination of compressed air and proper pressure levels to function safely and effectively. When the air pressure drops below the necessary threshold, the brakes may not engage or may engage with insufficient force, resulting in a diminished ability to slow down or stop the vehicle.

This loss of braking power can create dangerous situations, especially when quick stops are needed, or when driving in conditions that require reliable braking response. Proper maintenance and monitoring of air pressure levels are crucial to ensure safety while operating vehicles equipped with air brakes. This is why maintaining adequate air pressure is a fundamental aspect of air brake system operation and safety.
