NHTSA Campaign 79V253000

SERVICE BRAKES, AIR:SUPPLY:LOW PRESSURE WARNING:SWITCH

Issued by HENDRICKSON MFG. CO. · Reported Nov 15, 1979 · 1,246 vehicles 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".

Remedy

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.
