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.
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.
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.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Description of Defect:
According to Haldex, “during the assembly of the Life Seal actuator unit, the internal rubber diaphragm may not be fully seated in the spring piston of the parking brake section, thereby causing internal leakage from the service section past the diaphragm and 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 dragging and overheated wheel end foundation service brakes.”
The potential risk is for overheating at the wheel end, which increasing the risk of fire.
Models/ Model Years Affected:
Volvo: 899 in total (670 U.S., 187 Canada, 42 Mexico).
The National Traffic and Motor Vehicle Safety Act and Canadian Motor Vehicle Safety Act
requires dealers to ensure that all new and used vehicles are free of safety defects and comply
with all relevant safety standards at the time of delivery to the consumer.
Dealers should make their personnel aware of the safety recall. In the event that a dealer has a
vehicle included in the safety recall in their inventory to be sold, the condition must be corrected
before releasing it to a customer.
- Vehicle will be posted on the Trucks Dealer Portal January 26, 2015.
- Repair Instructions are tentatively scheduled for release no later than March 19, 2015.
- Owner Notices are scheduled to be mailed on or before March 19, 2015.

SAFETY RECALL INFORMATION:
(March 2015) During the assembly of the Life Seal actuator unit in the Halidex brake chamber, the internal rubber diaphragm may not have been fully seated in the spring piston of the parking brake section. Improper seating of the rubber diaphragm may cause internal air leakage from the service section past the diaphragm and potentially trap air (buildup air pressure) in the parking brake section. If the trapped air is not vented, the buildup in air pressure may prevent full release of the actuator unit. Additionally, the trapped air may induce dragging, overheated wheel end foundation service brakes, and may increase the risk of fire.
VOLVO Trucks has received no reports of personal injury as a result of this condition. Therefore, VOLVO considers this as a proactive measure to protect the public and VOLVO’s customers from the potential risk associated with this defect.
