1991–1997 Pierce Fire Truck Recall

On certain fire trucks, high speed cycling applications of the two-way Midland check valve by engagement of the Automatic Traction Control (ATC) system can cause the internal piston on the check valve to deteriorate. If this occurs, metal particles might break off the piston and obstruct the rear brake control valve. The obstruction might cause a loss of air pressure to a wheel brake chamber, resulting in a reduction of vehicle braking force, which in turn could lengthen the expected braking distance. Correction: Dealers will replace the two-way check valve.
