Technician a says that riveted linings are more common on light-duty vehicles since they are less expensive to build and the rivets can fail under very high temperatures of heavy-duty use. technician b says that bonded linings are preferred on heavier-duty or high-performance vehicles. who is correct?

Neither technician is correct. Bonded linings are actually better suited for light duty vehicles since they are cheaper to produce and the rivets can actually fail under heavy duty use. Riveted linings are used on heavier duty vehicles because the metal in the rivets provides an important mechanical connection.
