The objective of this work is to study the wear analysis of brake pad in braking operation to estimate the weight loss and wear rate of different bake pad materials used in automotive applications. The braking system’s in an automotive slow down or stop the automobile entirely by transforming its kinetic energy to heat energy. During breaking due to rapid interaction between the pad and rotor interface generates high temperatures, hence the brake pad must absorb heat rapidly to survive at high temperatures with no wear. This work investigates and deliberates innumerable environment-friendly and healthy substitute materials to asbestos. Generally brake pad friction substance is made of different materials such as binders, filler content, additives and reinforcements, to satisfy the specifications and adjust their percentage effects on the wear properties. Over the previous few years, the brake pads have been manufactured of asbestos material with enough electrical, tribological as well as physical properties, but that causes cancer and many other health issues, and therefore its use is redundant. In this work three specific mixtures are used with adjusted ratios of ingredients and observed their impact on the tribological characteristics. More weight loss (8–10%) is observed for the asbestos material as compared to the non-asbestos material. The wear rate increases with increase in contact pressure between the brake surfaces under dry condition. As the wear rate of non-asbestos material and CL3003 material is less as compared to asbestos, hence these can be a good option for the replacement to asbestos.
