- Notes
- Possibility the midland-ross air brake application valve assembly internalvalve cage may deteriorate and crack and eventually fail.if a failure occurs, the valve piston could be pushed out of the valve body, resulting in a rapid loss of air at the application valve causing a loss of brake action.(correct by replacing internal valve cage with one of improved construction and material.)

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