What's wrong?
The Haldex Life Seal brake chamber is part of the air brake system on the affected 2015 Freightliner trucks, including the Cascadia, Business Class M2, 108SD, 114SD, 122SD, Coronado, 4700, and 4900. In an air brake system, compressed air moves a diaphragm inside the brake chamber. That movement turns air pressure into mechanical force that applies the brake at the wheel.
On the recalled trucks, the diaphragm inside the brake chamber was not seated correctly during manufacture. When that diaphragm sits out of position, the chamber does not move as designed. The result is brake drag, which means the brake stays partly applied instead of fully releasing after the driver lets off the pedal.
The filing does not identify a driver warning sign before the brake chamber problem appears. There is no warning sign before failure. A driver who notices dragging, heat, odor, or unusual brake feel should treat it as a service issue and have the truck checked.
