ON CERTAIN MEDIUM DUTY CONVENTIONAL AND TILT CAB TRUCKS EQUIPPED WITH 7.8L DIESEL ENGINES AND AIR BRAKES, THE AIR COMPRESSOR MAY NOT BUILD ENOUGH AIR PRESSURE TO SUPPORT THE AIR BRAKE SYSTEM.

Consequence: IF THIS CONDITION WERE TO OCCUR WHILE THE VEHICLE WAS STATIONARY (BRAKES APPLIED) THE AIR BRAKES WOULD REMAIN APPLIED AND PREVENT THE VEHICLE FROM MOVING. IF THIS CONDITION WERE TO OCCUR WHILE THE VEHICLE WAS IN MOTION, THE DUAL SYSTEM AIR PRESSURE GAUGES WOULD REGISTER THE DROP IN PRESSURE. IF THE PRESSURE CONTINUED TO DROP, THE LOW AIR PRESSURE WARNING BUZZER AND WARNING LAMP WOULD ACTIVATE AS DESIGNED, WARNING THE DRIVER TO MOVE THE VEHICLE TO A SAFETY LOCATION. IF THE DRIVER IGNORES THESE WARNINGS AND CONTINUES TO DRIVE THE VEHICLE, AND IF THERE WAS A CONTINUED LOSS OF PRESSURE, THE REAR SPRING PARKING BRAKES WOULD AUTOMATICALLY APPLY, PREVENTING THE TRUCK FROM BEING DRIVEN.

Remedy: DEALERS WILL REPLACE THE AIR COMPRESSOR HEAD. THE RECALL BEGAN ON MAY 23, 2007. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, OR ISUZU AT 1-800-255-6727.
