The Right Drum for the Right Application

Drum brakes operate on a simple principle: brake shoes press against the sides of hollow drums, creating friction and slowing the vehicle. Significant research and refinement is involved in the development of a line of drums that addresses ever-shorter stopping distance requirements, heavier duty cycles, and brake fade in such a wide variety of conditions and applications.

For example, identical vehicles operating in different conditions require different drums. Finding the right brake drums with a balance of weight, heat transfer efficiency and service life can be a challenge – but one you can quickly meet with a visit to your Peterbilt dealer. There, you will find a range of options from TRP® that represent the best in brake drum technology.
