What result may occur if an air filter is plugged in an air brake system?

When an air filter in an air brake system is plugged, it can severely restrict airflow to the compressor. This impediment can prevent the compressor from effectively drawing in the necessary air to generate and build pressure. As a result, the compressor may not be able to build air pressure within the required time, which is crucial for the proper functioning of the air brake system. If the pressure builds slowly, it can lead to delayed brake application and compromised braking performance, which can be hazardous. The system relies on adequate airflow to function correctly, and a clogged air filter disrupts this process.
