VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCKS. THE AIR SUSPENSION CONTROL VALVE SUPPLY LINE WAS NOT PLUMBED THROUGH AN AIR PRESSURE PROTECTION VALVE. IN THE EVENT OF A FAILURE, THERE WOULD BE LOSS OF AIR PRESSURE IN THE 'B' SYSTEM AIR RESERVOIR THAT SUPPLIES AIR PRESSURE FOR THE FRONT STEER AXLE BRAKES.
THIS CONDITION WOULD RESULT IN INCREASED STOPPING DISTANCES.
DEALERS WILL INSTALL THE NECESSARY AIR PRESSURE PROTECTION VALVE.
UNDERCOATING APPLIED TO THE INSIDE OF THE CAB SHELL SQUEEZED OUT DURING ASSEMBLY ONTO THE BRAKE PEDAL PLUNGER.
UNDERCOATING ON THE PLUNGER MAY CAUSE THE PLUNGER TO STICK RESULTING IN INCREASED BRAKE PEDAL EFFORT AND/OR SLOW RELEASE OF THE BRAKES INCREASING THE POTENTIAL FOR A VEHICLE ACCIDENT.
DEALERS WILL CLEAN THE UNDERCOATING FROM THE BRAKE PEDAL PLUNGER ASSEMBLY, LUBRICATE AND REINSTALL THE BRAKE PEDAL PLUNGER ASSEMBLY.
