NHTSA recall 15V021000
Parking brake › Driveline › Hydraulic › Actuator
Polar Tank APX0 Trailer and 2 more
The defect
Polar Tank Trailer, LLC (Polar) is recalling certain model year 2015 SRJH, APX0, and ATB6 trailers manufactured August 27, 2014, to November 29, 2014, 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
Polar will notify owners, and dealers will inspect and replace the actuators, as necessary, free of charge. The recall began April 2, 2015. Owners may contact Polar customer service at 1-320-746-2255. Polar's number for this recall is 14E075.
