Recall 79V253000
Service Brakes, Air › Supply › Low Pressure Warning › Switch — Hendrickson · reported 15 Nov 1979 · 1,246 vehicles potentially affected
What's wrong
THE LOW AIR PRESSURE SWITCHES USED ON SOME OF THE INVOLVED VEHICLES HAVE A MANUFACTURING TOLERANCE THAT ISSUES A WARNING ONLY WHEN THE PRESSURE DROPS A FEW POUNDS PER SQUARE INCH BELOW 60 PSI. AS A RESULT, THEY DO NOT COMPLY WITH FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS".
The fix
IF THE OWNER, UPON RECEIPT OF A POST CARD, INDICATES A COMPLIANCE, THE DEALER WILL REIMBURSE OWNER $5.00 FOR COST OF TEST. IF OWNER INDICATES A NON-COMPLIANCE, THE DEALER WILL SEND TWO REPLACEMENT SWITCHES AND A CHECK FOR $5.00 TO COVER BOTH THE SYSTEM TEST AND SWITCH REPLACEMENT.
VEHICLE DESCRIPTION: TRUCKS, DRILL RIGS, CRANE CARRIERS, AND SCHOOL BUSES.SYSTEM: SERVICE BRAKES; AIR PRESSURE WARNING SWITCHES.CONSEQUENCES OF DEFECT: IF THE LOW AIR PRESSURE WARNING SWITCH IS NOT ACTIVATEDAT PRECISELY 60 PSI, THE DRIVER WOULD NOT BE FOREWARNED OF POTENTIAL LOSS OFBRAKING ACTION. THIS COULD CONTRIBUTE TO A VEHICLE ACCIDENT.
