Hazard description
On certain vehicles, the hand operated trailer brake control may have a partially blocked delivery port, which can cause the trailer brakes to be slow to apply an release when operated by the hand control valve. If this hand control valve is used while the vehicle is in motion, the slow brake application or release may contribute to loss of control of the vehicle causing a collision, possibly resulting in property damage, personal injury or death. Correction: The dealer will replace the defective valves.
