What’s wrong with it?
THE CATCHING OF THE PISTON HEAD/PLATE ON THE REDUCING RING MAY LOCK UP THE CORRESPONDING FRONT AIR DISC BRAKE WHICH MAY IMPACT THE OPERATOR’S ABILITY TO STEER OR CONTROL THE VEHICLE.
PACCAR IS RECALLING 86 MY 2009 KENWORTH T660, T800, W900, AND PETERBILT 386, 365, AND 388 TRUCKS EQUIPPED WITH BENDIX FRONT AIR DISC BRAKES.
THE SIZE 14 SERVICE CHAMBER OF CERTAIN FRONT AIR DISC BRAKES MAY HAVE BEEN CONTAMINATED WITH GREASE BETWEEN THE PISTON HEAD/PLATE AND THE DIAPHRAGM.
WHEN BRAKING PRESSURE IS APPLIED, THE GREASE MAY ALLOW THE PISTON HEAD/PLATE TO SLIP OFF CENTER AND CATCH ON THE REDUCING RING OF THE SIZE 14 SERVICE CHAMBER.

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.
