Summary: Parking brakes on the involved vehicles may not release or release completely. This could lead to abnormal heating of the rockwell parking brake drum during vehicle operation. This may cause burning or thermal cracking of the drum surface. The weakened drum then becomes subject to failure under the centrifugal forces of the propshaft rotation which pull the drum outwards when it is rotating rapidly around the propshaft center.
Remedy: The dealer will replace the existing brake drum with rockwell part #3219-H-4350, without charge to owner.
Notes: Vehicle description: buses.system: service brakes; parking brake, drum.consequences of defect: if such a failure occurs when the propshaft isoperating, the drum can disintegrate with an explosive force. This could causeloss of vehicle control and an accident.

Has your Flxible been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Flxible dealer can also check your VIN. Recall repairs are free.
