ZF North America is recalling approximately 2,493 park brake actuation air brake systems and specific Haldex inversion relay valves used in commercial vehicles. An internal piston within the inversion valve can fail, which causes a delay in the parking brake engaging. This delay can lead to the vehicle moving unexpectedly even after the parking brake is applied, which increases the risk of a crash. The affected parts include Haldex inversion relay valves with part numbers 9718990020 and RKN28032.
An internal component failure in the valve prevents the parking brake from activating immediately. This can result in unintended vehicle rollaway, which poses a serious risk of collisions and injury to bystanders or drivers.
ZF will replace aftermarket equipment free of charge.
