The defect
ON CERTAIN BUSES EQUIPPED WITH A GRAHAM WHITE BRAKE AIR DRYER MODEL QBA15, THE BRAKE AIR DRYER TIMER DOES NOT FUNCTION PROPERLY. THE AIR ENTERING INTO THE BRAKE SYSTEM MAY NOT HAVE THE MOISTURE REMOVED. IF NOT PROPERLY DRAINED, SMALL ICE CRYSTALS MAY FORM IN THE BRAKE SYSTEM PREVENTING THE SYSTEM TO OPERATE THE BRAKES PROPERLY.
The risk
THE BUS MAY NOT PERFORM AS EXPECTED WHEN STOPPING, INCREASING THE RISK OF A CRASH.
The remedy
DAIMLERCHRYSLER IS WORKING WITH GRAHAM WHITE TO DEVELOP A REMEDY. OWNERS ARE BEING ASKED TO INSPECT THE WET BRAKE AIR TANK FOR MOISTURE BY USING A MANUAL DRAIN. ONLY TWO CUSTOMERS ARE INVOLVED AND HAVE BEEN CONTACTED.
