VEHICLE DESCRIPTION: SCHOOL AND TRANSIT BUSES EQUIPPED WITH BENDIX AIR BRAKES. BENDIX CHANGED THE INTERNAL DESIGN OF THE QR1C RELAY VALVE BY ADDING A HOLE IN THE INTERNAL DIAPHRAGM. WHEN THE HOLE IN THE DIAPHRAGM ALIGNS WITH THE HOLE IN THE VALVE BODY, THE BRAKE APPLICATION TIME INCREASES.
Safety risk
UNDER CERTAIN CONDITIONS, SUCH AS PARKED ON AN INCLINE, DRIVER ACTIVATES THE PARKING BRAKE BUT REMOVES FOOT FROM THE THREADLE VALVE, THE BUS COULD ROLL BEFORE THE PARKING BRAKE IS FULLY ENGAGED.
Manufacturer remedy
DEALERS WILL REPLACE THE DIAPHRAGMS WITH HOLES WITH SOLID DIAPHRAGMS FOR THE QR1C VALVES.
VEHICLE DESCRIPTION: MOTOR HOMES EQUIPPED WITH RIDEWELL TAG AXLES. SOME OF THE RIDEWELL TAG AXLE AND SUSPENSION ASSEMBLIES HAVE THE BRAKE S-CAMS INCORRECTLY INSTALLED.
Safety risk
THIS CONDITION COULD INCREASE THE STOPPING DISTANCE OF THE VEHICLE, INCREASING THE RISK OF A CRASH.
Manufacturer remedy
OWNERS WILL BE PROVIDED WITH INSTRUCTIONS FOR INSPECTING THE BRAKE S-CAM AND IF FOUND INCORRECT, INSTRUCTIONS FOR CORRECTION OF THE S-CAM INSTALLATION.
