Airborne particulate emissions originating from the wear of pads and rotors of disc brakes contribute up to 50% of the total road\nemissions in Europe. The wear process that takes place on a mesoscopic length scale in the contact interfaces between the pads\nand rotors can be explained by the creation and destruction of contact plateaus. Due to this complex contact situation, it is hard to\npredict how changes in the wear and material parameters of the pad friction material will affect the friction and wear emissions.\nThis paper reports on an investigation of the effect of different parameters of the pad friction material on the coefficient of friction\nand wear emissions. A full factorial design is developed using a simplified version of a previously developed cellular automaton\napproach to investigate the effect of four factors on the coefficient of friction and wear emission. The simulated result indicates\nthat a stable third body, a high specific wear, and a relatively high amount of metal fibres yield a high and stable mean coefficient\nof friction, while a stable third body, a low specific wear, a stable resin, and a relatively high amount of metal fibres give low wear\nemissions.
