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

What’s wrong with it?

FAILURE TO CORRECTLY ADJUST THE SLACK CAUSES THE BRAKESTO BECOME OUT-OF-ADJUSTMENT AND RESULTS IN REDUCED BRAKING POWER, INCREASEDSTOPPING DISTANCES, AND A POSSIBLE ACCIDENT.

IMPROPER INSTALLATION OF EATON AUTOMATIC SLACK ADJUSTER ON EATON AXLES EQUIPPED WITH AIR OPERATED S-CAM BRAKES.

THE SLACK ADJUSTER “FIXED ANCHOR BRACKET”, WHICH TRIGGERS THE AUTOMATIC BRAKE ADJUSTMENT, WAS IMPROPERLY LOCATED.

THE IMPROPERLY LOCATED ANCHOR BRACKET CAN DAMAGE THE AUTOMATIC SLACK ADJUSTER CONTROL ARM AND CAUSE THE SLACK ADJUSTER TO FAIL TO PERFORM THE MECHANICAL ADJUSTMENT FUNCTION FOR WHICH IT WAS DESIGNED.

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.
