AIR PRESSURE GAGES AND SWITCH
There are two pressure operated gages mounted in the right side of the instrument cluster panel that indicate pressure in
the airbrake reservoirs. They receive pressure from the reservoirs through flexible tubing. A pressure switch mounted on
the brake pedal valve closes the electrical circuit to a warning light mounted in the right side of the instrument cluster panel
when the vehicle looses air pressure.
