Blue Bird Vision School Bus: Brakes
Affects Blue Bird Vision School Bus · 2004 — about 3 vehicles.
The hazard
On certain vehicles, the under-hood firewall location of the air brake manifold may permit rainwater entry into the parking brake exhaust port fitting of the manifold. In freezing weather, this water could form ice blocking the exhaust port. When this occurs, the parking brake does not operate as designed. In the event that this condition should occur and the parking brake failed to apply, the bus could roll away resulting in property damage or personal injury. Correction: Dealer will install an air brake tubing extension to the exhaust port to relocate the opening away from the air brake valve manifold to prevent the potential for water to enter the exhaust port.
