Mertz Manufacturing due to an incomplete "knitting" of the iron at the time of casting, inadequate structural integrity of the slack adjuster housing can occur, which could cause the housing to break at the handle under normal operating loads.
The short version
MERTZ MANUFACTURING, LLC reported a problem with the service brakes, air slack adjusters. Here is what owners need to know.
DUE TO AN INCOMPLETE "KNITTING" OF THE IRON AT THE TIME OF CASTING, INADEQUATE STRUCTURAL INTEGRITY OF THE SLACK ADJUSTER HOUSING CAN OCCUR, WHICH COULD CAUSE THE HOUSING TO BREAK AT THE HANDLE UNDER NORMAL OPERATING LOADS.
IF THE SLACK ADJUSTER HOUSING WERE TO BREAK, THE WHEEL BRAKE TO WHICH THE SLACK ADJUSTER IS ATTACHED WOULD NO LONGER FUNCTION, CAUSING THE VEHICLE TO HAVE REDUCED BRAKING CAPACITY AND, IF MOUNTED ON THE STEER AXLE, THE VEHICLE COULD PULL TO ONE SIDE, POSSIBLY RESULTING IN A CRASH.
MERTZ WILL NOTIFY OWNERS AND THE SLACK ADJUSTERS WILL BE REPLACED FREE OF CHARGE.
