How does low air pressure affect braking performance?

Low air pressure has a significant impact on braking performance because air brakes rely on a specific pressure level to function effectively. When air pressure is low, the brake components may not receive the necessary force to engage properly. This can result in inadequate braking power, as the system may struggle to apply enough pressure to the brake chambers.

In critical situations, low air pressure can lead to brake failure, which significantly compromises vehicle safety. The vehicle may not stop when needed, increasing the risk of accidents. Proper maintenance and monitoring of air pressure are crucial for ensuring that the braking system operates within safe parameters, keeping both the driver and others on the road protected from potential hazards.
