The short answer

NHTSA received FREIGHTLINER CORP.’s report on Jun 21, 1978. Copied from NHTSA on Oct 20, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

The notice gives no hazard in a field of its own.

THE CHECK VALVE, LOCATED ON THE INLET SIDE OF THE PRIMARY AND SECONDARY AIR TANKS MAY CRACK IN THE FEMALE FITTING AREA AND CAUSE A SLOW LOSS OF AIR.

A LEAKING VALVE WILL REDUCE AIR PRESSURE AND PARTIAL OR COMPLETE LOSS OF BRAKES ON THOSE AXLES THAT DEPEND UPON THAT PART OF THE SYSTEM COULD OCCUR.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • This recall names only model years before 2015, which have no pages here. Your VIN, at NHTSA, says which recalls are open on a vehicle.
  • How many have been returned or fixed isn’t in the notice.
