The defect
Volvo Trucks North America (Volvo) is recalling certain model year 2015 and 2016 VNX and VNL trucks manufactured from May 20, 2014, through March 6, 2015, equipped with certain Haldex Life Seal Type 30/30 Long Stroke Air Brake Actuators manufactured January 9, 2014, to October 28, 2014. The affected actuators may have an incomplete attachment of the internal rubber diaphragm to the actuation mechanism of the parking brake section of the Life Seal actuator.
The risk
If the diaphragm is not completely attached, there may be internal leakage from the service section past the diaphragm, potentially trapping air pressure in the parking brake section. This air pressure in turn, if not vented, may prevent full release of the actuator unit, and may induce brake drag and may result in overheated wheelend service brakes, increasing the risk of a fire.
The remedy
Volvo will notify owners, and dealers will inspect the brake actuator and replace, as necessary, free of charge. The recall began March 20, 2015. Owners may contact Volvo customer service at 1-800-528-6586. Volvo's number for this recall is RVXX1501.
