The quick release air valve may contain a valve disc that balloons when the parking brakes are applied and prevent the parking brakes from setting. Consequence of defect: although the parking brake is applied, the parking brakes may not be set. This could allow an unattended vehicle to roll and cause an accident.
Replace the valve disc in the quick release air valve.
