What could happen if an air compressor governor is malfunctioning?

Answer: C — There could be improper air pressure

If an air compressor governor is malfunctioning, it could lead to improper air pressure within the braking system. The governor is responsible for controlling the air pressure supplied to the brakes by regulating when the compressor should turn on and off. If it fails to operate correctly, it can either lead to insufficient air pressure for the brakes to function effectively or excessive pressure that could cause damage to brake components. Proper air pressure is crucial for ensuring that the brakes respond appropriately during operation, allowing for safe vehicle control and effective braking performance.
