WASHINGTON, D.C. --- Ferrara Fire Apparatus Inc. is recalling 89 MY 2008-2009 Inferno and Igniter fire trucks equipped with certain Haldex quick release valves. 

The rubber diaphragm inside the valves may experience delamination, resulting in significant levels of air pressure leakage past or through the diaphragm. Another consequence could be the development of a bubble in the diaphragm, which may trap air pressure in the valve and not allow the service brakes to release. 

This condition could lead to malfunction of the air brake system, increasing the chances of a crash, the National Highway Traffic Administration reported. 

Ferrara will notify owners and make the necessary repairs free of charge. The recall is expected to begin on or before June 26. 

Truck owners can contact Ferrara at (225) 567-7100.
