The defect
PARKING BRAKES ON THE INVOLVED VEHICLES MAY NOT RELEASE OR RELEASE COMPLETELY. THIS COULD LEAD TO ABNORMAL HEATING OF THE ROCKWELL PARKING BRAKE DRUM DURING VEHICLE OPERATION. THIS MAY CAUSE BURNING OR THERMAL CRACKING OF THE DRUM SURFACE. THE WEAKENED DRUM THEN BECOMES SUBJECT TO FAILURE UNDER THE CENTRIFUGAL FORCES OF THE PROPSHAFT ROTATION WHICH PULL THE DRUM OUTWARDS WHEN IT IS ROTATING RAPIDLY AROUND THE PROPSHAFT CENTER.
The remedy
THE DEALER WILL REPLACE THE EXISTING BRAKE DRUM WITH ROCKWELL PART #3219-H-4350, WITHOUT CHARGE TO OWNER.
