The hazard

On certain trucks, the air governor was assembled with a blank plug instead of a breather. Without the breather, the air governor may not be able to detect the loss of pressure in the air system during normal use, which may result in a slow activation of the emergency spring brakes. Although the operator is warned of low air pressure by audible and visual warning alarms, a crash causing property damage, personal injury or death is possible if these warnings are ignored. Correction: Dealers will replace the blank plug with a breather, and inspect the system for proper function.
