Abstract
Friction characteristics of nine automotive brake friction materials contai ning different amounts of antimony trisulfide (Sb2S3) and zirconium silicat e (ZrSiO4) were investigated by using a brake dynamometer. Two different mo des of brake applications (drag mode and stop mode) were employed to study the change of friction coefficient and torque variation (friction force osc illation). Results showed that the relative amount of Sb2S3 and ZrSiO4 play ed important roles in determining the friction characteristics. Sb2S3 in th e friction material improved the friction stability and ZrSiO4 aggravated t he torque variation during brake applications. (C) 2000 Elsevier Science S. A. All rights reserved.
