Mack Trucks, Inc.: Parking Brake › Driveline › Hydraulic › Actuator
Mack Trucks, Inc. reported this defect to federal regulators on Jan 22, 2015 and put the number of vehicles at risk at 349. The repair is free for as long as the recall stands.
The defect
Mack Trucks, Inc. (Mack) is recalling certain model year 2015 and 2016 CXU and LEU trucks manufactured May 20, 2014, to March 24, 2015, equipped with certain Haldex Life Seal Type 30/30 Long Stroke Air Brake Actuators manufactured from January 9, 2014, through February 3, 2015. 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
Mack 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 Mack customer service at 1-610-709-2131. Mack's number for this recall is SC0387.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 15V025000.
