Recalls for 2016 Mack Cxu

DEFECT #1 - PARKING BRAKE:DRIVELINE:HYDRAULIC:ACTUATOR

Posted on: 2015-01-22
Description
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.

Consequence
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.

Corrective Action
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.

Notes
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.
