The braking performance of brake pad for railway vehicle was investigated in this study. The grooves number on the friction surface was considered in order to evaluate to braking performance. The purpose of this study is to optimize a brake pad design of friction surface on the basis of analyses of a combination of mechanical and thermal load due to braking conditions. The finite element method analysis was used to optimize the groove number of brake pad. The results of the thermal stress analysis on brake pad showed that the thermal stress for three groove pad was reduced to about 8% as compared to that for two groove pad. A full-scale brake dynamo test was carried out to characterize the braking performance such as friction coefficient, wear rate and braking temperature. The result of full-scale brake dynamo test showed that the grooves of brake pad were related to the variation of friction temperature and wear amount of brake pad under braking applications. In conclusion, the braking performance brake pad with three grooves on the friction surface was better than that of two groove pad.
