The development and advancement of new brake pad composition is still based on expensive and time-consuming trial-and-error experiments. The macroscopic friction and wear behavior is coupled with the growth and destruction of characteristic hard structures, so-called, "patches" which have a size of some 100 micrometers. Based on macroscopic assumptions and resulting sophisticated dynamic friction laws a cellular automaton model for an explicit insight into the interface dynamics has been developed. That model is enhanced in this paper in terms of a height coordinate to describe the three-dimensional topography dynamics. This especially regards the interaction between normal load distribution, friction load distribution, wear generation and the resulting change of topography. The respective algorithms are introduced and discussed. First results already show a consistency of the implemented laws so that this model in principle has the potential to formulate a correlation between pad compositions, friction phenomena and global wear rates.
