Microstructure and Roughness Analysis of Drum Brakes of Maruti 800

Abstract

The purpose of this paper was to focus on the basics of drum brake systems, so as to provide an in-depth microstructure analysis of the drum brake and the roughness value of the drum surface. As the roughness affects the braking capacity of linings on drum surface, it also allows the duration of service for the drum. This study has helped to know the amount of wear on drum and to minimum roughness value of drum surface that is required for safe braking.
