1993 Blue Bird Q-BUS

AN INCORRECT SIZE BRAKE CHAMBER MAY HAVE BEEN INSTALLED ON THE FRONT AND/OR REAR BRAKE ASSEMBLIES WHICH COULD AFFECT THE BRAKE BALANCE AND STOPPING DISTANCE.

RiskBRAKE IMBALANCE MAY CAUSE LOSS OF VEHICLE CONTROL DURING BRAKE APPLICATIONS; INCREASED STOPPING DISTANCE OR BRAKE APPLICATION COULD RESULT IN LOSS OF CONTROL AND AN ACCIDENT.

FixBUS OWNERS WILL BE PROVIDED WITH INSTRUCTIONS TO INSPECT THEIR VEHICLES AND PROVIDE BLUE BIRD WITH CERTAIN INFORMATION. BLUE BIRD WILL REVIEW THE INFORMATION AND, WHERE NEEDED, WILL FORWARD REPLACEMENT BRAKE CHAMBERS ALONG WITH REPLACEMENT INSTRUCTIONS TO THE VEHICLE OWNERS. BRAKE CHAMBER REPLACEMENT WILL BE PERFORMED BY THE VEHICLE OWNER OR A QUALIFIED REPAIR FACILITY.

THE HYDRAULIC HOSES WHICH INTERCONNECT WITH THE HYDRAULIC PUMP, HYDRAULIC RADIATOR FAN MOTOR AND POWER STEERING GEAR HAVE AN UNDERSIZED WIRE MESH CORE WHICH RESULTS IN AN IMPROPER HOSE END CRIMP. THE IMPROPER CRIMP CAN CAUSE A LEAK, EMPTYING THE POWER STEERING HYDRAULIC FLUID RESERVOIR, RESULTING IN LOSS OF POWER STEERING ASSIST.

RiskCOMPLETE LOSS OF POWER STEERING ASSIST CAN CAUSE LOSS OFVEHICLE CONTROL AND RESULT IN AN ACCIDENT.

FixOWNERS ARE BEING ASKED TO INSPECT HOSE FOR THE DATE CODE 3-1Q93 WHICH IS EMBOSSED ON THE HOSE COVER EVERY 18 INCHES. REPLACEMENT HOSES WILL BE PROVIDED. OWNERS CAN HANDLE THE REPAIR THEMSELVES OR HAVE A BLUE BIRD DISTRIBUTOR ASSIST THEM. OWNERS WILL BE REIMBURSED FOR THE LABOR CHARGES FOLLOWING COMPLETION OF THE RECALL WORK.

THE FRONT BRAKE AIR LINES ARE INCORRECTLY ROUTED THROUGH THE PRESSURE PROTECTION VALVE AT THE AUXILIARY WET TANK. THIS RESULTS IN LACK OF AIR PRESSURE TO THE FRONT BRAKES WHEN THE AIR PRESSURE IN THE AUXILIARY WET TANK DROPS BELOW 65 P.S.I., RESULTING IN INOPERABLE FRONT BRAKES.

RiskWHEN THERE IS NO FRONT BRAKE APPLICATION, STOPPINGDISTANCE INCREASES, AND THERE IS AN INCREASED RISK OF ACCIDENT.

FixCORRECTLY REROUTE THE BRAKE LINES.
