Volvo VNX, VNL: Parking brake — actuator

Affects Volvo VNX, VNL · 2015–2016 — about 170 vehicles.

The hazard

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.

What to do

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.
