The pressure governor is a feature of which system?

Explanation:
The pressure governor is part of the air brake system. Its job is to regulate the air pressure in the brake lines by controlling the air compressor. When pressure in the system drops, the governor allows the compressor to start and build pressure; once the pressure reaches its upper limit, the governor shuts the compressor off. This keeps the system within a safe operating range so there’s always enough pressure to apply the brakes without over-pressurizing the tanks. It isn’t a feature of the Allison transmission, the electrical system, or the hydraulic system.
