Presentation Description

In automotive industries asbestos is most common material used in braking system but it is banned in many of the countries because of its carcinogenic nature. Therefore many of the scientists focus to develop new material with minimum cost which is eco-friendly. However, so many researches hopped to come up with equal efficient alterative material as asbestos and more than three thousand materials are available in market with different brand and each one have its unique properties. In this paper review of brake pad materials are discussed with their advantages and disadvantages with their properties and understand the fundamental concept regarding each material which is to prepare a best material.
