Microstructure and Roughness Analysis of Drum Brakes of Maruti 800

The purpose of this paper focuses on the basic describing of drum brake systems in order to provide an in-depth microstructure analysis of the drum brake and also 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 of the drum This study will help because the study of wear will allow us to know the amount of wear on drum and to minimum roughness value of drum surface that is required to safe braking
