Why is it important to monitor the air pressure in the brake system?

Monitoring the air pressure in the brake system is crucial primarily to maintain safe and effective braking. The air brake system operates using compressed air to activate the brake components. If the air pressure is too low, it can lead to insufficient braking power, which increases the risk of accidents or inability to stop the vehicle in emergency situations. Conversely, excessive air pressure can also cause issues, such as brake drag or uneven wear. Therefore, keeping the air pressure within the manufacturer's specified range ensures that the brakes function optimally, providing reliable stopping power and enhancing overall safety on the road.

In addition to safety, consistent monitoring also contributes to the longevity of the brake components and overall vehicle performance, which is why this aspect is emphasized in brake system maintenance practices.
