Description
Oshkosh is recalling 302 my 2008 t-series, tx, sta, h, p, s and h-tractor, airport rescue, firefighting, commercial, concrete mixer and military trucks and highway vehicles equipped with haldex air brake system control valve.  The rubber diaphragm used inside the quick release valve (qrv) may delaminate and may cause leakage levels past and/or through the diaphragm in excess of permissible specifications, or could cause a restriction in the air flow, thereby effecting pressure delivery to the service brakes and not allow the service brakes to release.

Consequence
Malfunction of the air brake system could result in a vehicle crash.

Corrective Action
Oshkosh is working with haldex and will inspect and replace all effected qrvs free of charge.  Please see 09e-004.  The recall is expected to begin during june 2009.  Owners may contact haldex at 1-620-365-6911 or oshkosh at 1-920-235-9151.
