SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE
CERTAIN FREIGHTLINER SCHOOL BUS CHASSIS, HEAVY TRUCKS, AND THOMAS BUILT SCHOOL BUSES MANUFACTURED BETWEEN JULY 2002 AND JULY 3, 2007, EQUIPPED WITH BENDIX SR-7 SPRING BRAKE CONTROL VALVES. THE PARKER SCV BRASS 90 DEGREE SINGLE CHECK VALVES (SCV) WHICH ATTACH TO THE SUPPLY PORT OF A BENDIX SR-7 SPRING BRAKE MODULATING VALVE CAN BREAK APART. PIECES OF THE PARKER SCV CAN BECOME LODGED INSIDE THE SR-7 SPRING BRAKE MODULATING VALVE, POTENTIALLY CAUSING EITHER LEAKAGE OUT OF THE SR-7 VALVE OR PREVENTING AIR FROM PROPERLY EXHAUSTING FROM THE SR-7 VALVE. ALSO, DUE TO A MANUFACTURING DEFECT IN THE INTERNAL RUBBER CHECK VALVE INSIDE THE SR-7 SPRING BRAKE MODULATING VALVES, THE VALVES CAN BECOME DEFORMED AND NOT SEAT PROPERLY.
