Recall 13V056 affects 171 2011-2012 Orion Vii transit buses for leaking brake chambers that overheat brakes. Repair is free at any franchised Orion dealer.
Orion is recalling 171 2011-2012 Vii transit buses equipped with disc brakes and MGM brake components because leaking brake chambers can leave the parking brake dragging after release. Dragging brakes overheat brake components and raise the risk of a fire, and the dealer repair will be free once available.

What's wrong?
The parking brake chamber on the 2011-2012 Orion Vii is part of the air-brake parking system. It uses air pressure to hold the parking brake released while the bus is in service, then lets the parking brake apply when air pressure is removed. On buses with disc brakes and MGM brake components, that chamber has to seal correctly so the brake is fully released when the driver expects it to be released.
On affected buses, the brake chamber leaks pressure. With less release pressure available, the parking brake drags even though it is supposed to be off. That drag keeps brake parts in contact while the bus is moving, and NHTSA campaign 13V056 identifies overheated brake components as the safety concern.
There is no warning sign before failure. A driver or technician should treat any sign that the parking brake is not fully releasing as a reason to stop and have the bus inspected.
Who's affected?
Spans the 2011 and 2012 model years, with the same parking brake air chamber listed for both.

What's the safety risk?
Overheated brake components can result in a fire. If your VIN is included, schedule recall service promptly and treat any sign of brake overheating as a reason to stop using the vehicle until a dealer checks it. Repair will be free at any franchised Orion dealer once available.
