NHTSA recall 95V020000
Service brakes, air › Supply › Governor
Oshkosh VC26RD and 3 more
The defect
Air compressor governor sensing line does not sense both front and rear brake system reservoir pressure. A front brake system air leak will not be sensed by the governor and the compressor will fail to resupply the front air system causing a reduction of the front brake system performance.
The risk
This condition can cause loss of braking capability and increase the potential for a vehicle accident.
The remedy
Dealers will relocate the one way check valve in the inlet air line to the rear service tank and a pressure protection valve will be added to allow the governor to sense both front and rear brake system reservoir pressure.
