An Investigation of the Role of Wear and Friction Film Influencing the Friction Coefficient of Brakes: Mechanism of Brake Fade 2020-01-1630

Commercial heavy truck drum linings of 4 different compositions were tested using the Chase tester under constant loads and temperatures at a constant speed in order to find out how lining wear might affect the friction coefficient. When the lining wear increases, the friction coefficient increases linearly under a condition of constant load, speed and temperature. However, when the lining wear approaches zero, the friction coefficient still remains relatively high, indicating other factors are also involved in controlling friction such as interface deformation and others. As the temperature increases or the load increases, the wear contribution to the friction becomes less and less effective. All these observations are discussed and explained in terms of wear particle formation and friction film behavior.
