The defect
Spartan Motors, Inc. (Spartan) is recalling certain model year 2013-2015 Gladiator, DR, K2, K3, MetroStar, MM, and NVS vehicles manufactured December 14, 2011, to October 21, 2014, equipped with certain Wabco Quick Release Valves with Double Check. In the affected valves, the rubber diaphragm may be damaged by sharp edges on the valve seat ribs, reducing the available air pressure in the air tanks.
The risk
The reduced air pressure levels may reduce braking performance and/or the parking brakes could reapply, increasing the risk of a crash.
