THE HEAT GENERATED FROM THE BRAKES RESULTED IN A TIRE FIRE THAT ENGULFED THE REAR OF THE COACH.   IT APPEARS THAT THE PROBLEM MAY BE TIED TO SUB-ZERO TEMPERATURES AND BUS WASHING AND ITS EFFECT ON THE WABCO  AUTOMATIC TRACTION CONTROL (ATC) SYSTEM. THERE HAVE BEEN VERY SIMILAR PROBLEMS REPORTED ON OTHER BUSES EQUIPPED WITH THE WABCO SYSTEM.  THERE SEEMS TO BE A TENDENCY FOR THE ABS OR ATC VALVE EXHAUST PORT TO FREEZE UP DURING EXTREMELY COLD WEATHER CONDITIONS.  DURING AN ABS OR AN ATC EVENT, AIR IS NOT ALLOWED TO ESCAPE IN A NORMAL MANNER RESULTING IS DRAGGING BRAKES.     IN SEPTEMBER OF 2002 RFTA RECEIVED FSRP FROM NEOPLAN  TO ADDRESS SLOW RELEASE TIMES OF BRAKES  ON NAPOLEON ARTICULATED BUSES EQUIPPED WITH MULTI-RELAY AND ATC VALVES.  THOSE MODIFICATIONS WERE DONE BY RFTA.   GEORGE FISHER, A SERVICE TECHNICIAN WITH WABCO CONTACTED ME ABOUT THE PROBLEM WITH THESE UNITS.  I EXPLAINED TO HIM HOW WE THOUGHT THAT WE ISOLATED THE PROBLEM TO THE EXHAUST MUFFLER ON THE ATC VALVE.   I REVIEWED THE FSRP HIM.  ACCORDING TO GEORGE, WABCO HAD USED THAT DESIGN SEVERAL YEARS AGO, BUT DISCONTINUED IT BECAUSE OF THE VERY PROBLEM RFTA WAS EXPERIENCING.   WABCO DETERMINED WITH THAT DESIGN THAT THE CHECK VALVE WOULD SOMETIMES STICK AND CAUSE A NON- RELEASE THAT COULD OCCUR WITH A ATC EVENT OR A SERVICE BRAKE APPLICATION.  WABCOS POSITION IS THAT NEOPLANS FSRP WAS THE CAUSE OF THE NON-RE","canonical_url":"https://api.morvs.ai/vehicle-complaint/572992"},{"cmplid":"566244","date_received":"2005-12-16","make":"NEOPLAN","model":"AN440L","model_year":2002,"deaths":0,"injured":0,"fire":1,"crash":0,"component_desc":"SERVICE BRAKES, AIR","description":"THE REAR BRAKES ON TWO NEOPLAN AN 460 ARTICULATED BUSES APPEARED TO APPLY FOR NO APPARENT REASON RESULTING IN TWO TIRE FIRES AND ONE FIRE THAT ENGULFED THE ENTIRE REAR OF ONE BUS.  *NM","canonical_url":"https://api.morvs.ai/vehicle-complaint/566244"},{"cmplid":"121587","date_received":"1998-10-20","make":"NEOPLAN","model":"AN440","model_year":1998,"deaths":0,"injured":0,"fire":1,"crash":0,"component_desc":"ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR","description":"EXTREME EXOTHERIC REACTION IN EXHAUST CATALYST GENERATED SUFFICIENT LOCALIZED TEMPERTURE TO IGNITE SURROUNDING MATERIAL, RESULTING IN FIRE AND DAMAGE TO REAR PORTION OF TRANSIT BUS.","canonical_url":"https://api.morvs.ai/vehicle-complaint/121587"},{"cmplid":"121588","date_received":"1998-10-20","make":"NEOPLAN","model":"AN440","model_year":1997,"deaths":0,"injured":0,"fire":1,"crash":0,"component_desc":"ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR","description":"EXTREME EXOTHERMIC REACTION IN EXHAUST CATALYST GENERATED SUFFICIENT LOCALIZED TEMPERATURES TO IGNITE SURROUNDING MATERIAL, RESULTING IN FIRE AND DAMAGE TO REAR PORTION OF TRANSIT BUS.","canonical_url":"https://api.morvs.ai/vehicle-complaint/121588"},{"cmplid":"121590","date_received":"1998-10-20","make":"NEOPLAN","model":"AN440","model_year":1996,"deaths":0,"injured":0,"fire":1,"crash":0,"component_desc":"ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR","description":"EXTREME EXOTHERMIC REACTION IN EXHAUST CATALYST GENERATED SUFFICIENT LOCALIZED TEMPERATURE TO IGNITE SURROUNDING MATERIAL, RESULTING IN FIRE AND DAMAGE TO THE REAR PORTION OF THE TRANSIT BUS.","canonical_url":"https://api.morvs.ai/vehicle-complaint/121590"},{"cmplid":"121605","date_received":"1998-10-20","make":"NEOPLAN","model":"AN440","model_year":1995,"deaths":0,"injured":0,"fire":1,"crash":0,"component_desc":"ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR","description":"EXTREME EXOTHERMIC REACTION IN EXHAUST CATALYST GENERATED SUFFICIENT LOCALIZED TEMPERATURES TO IGNITE SURROUNDING MATERIAL, RESULTING IN FIRE AND DAMAGE TO REAR PORTION OF TRANSIT BUS.","canonical_url":"https://api.morvs.ai/vehicle-complaint/121605"},{"cmplid":"121608","date_received":"1998-10-20","make":"NEOPLAN","model":"AN440","model_year":1995,"deaths":0,"injured":0,"fire":1,"crash":0,"component_desc":"ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR","description":"EXTREME EXOTHERMIC REACTION IN EXHAUST CATALYST GENERATED SUFFICIENT LOCALIZED TEMPERATURES TO IGNITE SURROUNDING MATERIAL, RESULTING IN FIRE AND DAMAGE TO REAR PORTION OF TRANSIT BUS.","canonical_url":"https://api.morvs.ai/vehicle-complaint/121608"},{"cmplid":"121612","date_received":"1998-10-20","make":"NEOPLAN","model":"AN440","model_year":1995,"deaths":0,"injured":0,"fire":1,"crash":0,"component_desc":"ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR","description":"EXTREME EXOTHERMIC REACTION IN EXHAUST CATALYST GENERATED SUFICIENT LACALIZED TEMPERATURES TO IGNITE SURROUNDING MATERIAL, RESULTING IN FIRE AND DAMAGE TO REAR PORTION OF TRANSIT BUS.","canonical_url":"https://api.morvs.ai/vehicle-complaint/121612"}]}
