Brake Linings as Related to Brake Drums and Brake Performance 670502

It is necessary to consider the brake lining and brake drum as a mating pair for optimum performance. Some of the characteristics of brake linings, the interrelationship of the brake drum, and their combined effect on certain aspects of brake performance are discussed. Temperature, rubbing speed, unit pressure, and mating surface material are factors affecting the coefficient of friction of the lining. Brake maintenance also affects the operation of the lining as well as the entire brake system.By understanding the various properties of linings and drums and the concept of mating pairs, certain compromises can be reached which offer optimum performance for a specific set of operating conditions.
