It is important to consider the brake pad wear life in the development of brake system for automobiles, because of reducing customer complaint due to fast wear and designing optimal specifications. So in this paper, the factors related to pad wear are decided 4 categories as vehicle type, brake system type, brake pad properties and driving pattern. As to the factors, wear sensitivity is tested by brake dynamometer as well as the vehicle. In consequence, we analyzed sensitivity of the wear factors and developed the pad wear predicting program by MS Excel VBA. Finally, it is verified from vehicle driving test data as 84~96% of accuracy. As a result the brake pad wear life can be possible to predict reasonably in primary vehicle developing stage, and it helps to improve optimal design and reduce time & cost, too.
