MACK IS RECALLING 338 MODEL YEAR 2009 MRU AND LEU HEAVY DUTY TRUCKS MANUFACTURED FROM AUGUST 20 THROUGH NOVEMBER 26, 2008 EQUIPPED WITH CERTAIN HALDEX QUICK RELEASE VALVES "QRV". THE RUBBER DIAPHRAGM INSIDE THE QRV MAY EXPERIENCE DELAMINATION RESULTING IN SIGNIFICANT LEVELS OF AIR PRESSURE LEAKAGE PAST AND/OR THROUGH THE DIAPHRAGM, OR THE DEVELOPMENT OF A BUBBLE IN THE DIAPHRAGM WHICH MAY TRAP AIR PRESSURE IN THE VALVE AND NOT ALLOW THE SERVICE BRAKES TO RELEASE.
MALFUNCTION OF THE AIR BRAKE SYSTEM COULD RESULT IN A VEHICLE CRASH.
