- Summary
- On certain buses equipped with a graham white brake air dryer model QBA15, the brake air dryer timer does not function properly. The air entering into the brake system may not have the moisture removed. If not properly drained, small ice crystals may form in the brake system preventing the system to operate the brakes properly.
- Consequence
- The bus may not perform as expected when stopping, increasing the risk of a crash.
- Remedy
- Daimlerchrysler is working with graham white to develop a remedy. Owners are being asked to inspect the wet brake air tank for moisture by using a manual drain. Only two customers are involved and have been contacted.
- Notes
- Customers may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to http://www.safercar.gov.

Has your Orion 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 Orion dealer can also check your VIN. Recall repairs are free.
