The short answer
NHTSA received BENDIX COMMERCIAL VEHICLE SYSTEMS LLC’s report on Mar 24, 2011. 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?
IF THE SLACK ADJUSTER HOUSING WERE TO BREAK, THE WHEEL BRAKE TO WHICH THE SLACK ADJUSTER IS ATTACHED WOULD NO LONGER FUNCTION, CAUSING THE VEHICLE TO HAVE REDUCED BRAKING CAPACITY AND, IF MOUNTED ON THE STEER AXLE, THE VEHICLE COULD PULL TO ONE SIDE, POSSIBLY RESULTING IN A CRASH.
BENDIX IS RECALLING CERTAIN GUNITE AUTOMATIC SLACK ADJUSTERS MANUFACTURED FROM OCTOBER 15, 2010, THROUGH JANUARY 31, 2011, REPACKAGED AS BENDIX BRAND, PART NUMBERS 974294, 974296, 977142, AND 977143, AND SOLD FOR USE AS AFTERMARKET EQUIPMENT TO PACCAR PARTS DISTRIBUTORS.
ONE SLACK ADJUSTER WAS SOLD TO A MACK DISTRIBUTOR.
DUE TO AN INCOMPLETE “KNITTING” OF THE IRON AT THE TIME OF CASTING, INADEQUATE STRUCTURAL INTEGRITY OF THE SLACK ADJUSTER HOUSING CAN OCCUR, WHICH COULD CAUSE THE HOUSING TO BREAK AT THE HANDLE UNDER NORMAL OPERATING LOADS.

What the record doesn’t say
- NHTSA’s recall file doesn’t say whether anyone was hurt.
- Which ones, by part or lot: the recall’s report on NHTSA’s site gives them where the maker did; this file gives part numbers only where its maker listed them.
- How many have been returned or fixed isn’t in the notice.
