Pierce Manufacturing Inc. is recalling certain model year 2012-2013 Arrow XT and Velocity emergency vehicles, manufactured January 1, 2012, through June 14, 2013 and equipped with quarter-turn ball valves installed between the glad hands connectors and the parking brake system. If the ball valves are left in the closed position, air pressure can build up on the parking brake circuit side and prevent the application of the spring park brakes when the parking brake valve is activated in the cab.
This may allow the vehicle to unexpectedly roll, increasing the risk of personal injury or a vehicle crash.
Pierce will notify owners, and dealers will remove the quarter turn ball valves and connect the glad hand signal hose into the primary air tank, free of charge. The recall began on December 20, 2013. Owners may contact Pierce at 1-920-832-3000. Pierce's recall number is 74B243.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
