This paper presents the wear analysis of brake pad and disc of an automobile using pin on disc experimental setup. The brake pad, consisting of silicon carbide and many other binding and filling materials, is stamped with the graphene nanoplatelets. The graphene nanoplatelets are mixed with the cast iron which is usually used as disc for braking assembly of an automobile. The pins for the experimental purpose were made from the regular commercial brake pad and stamped brake pad. The mixing of the graphene in the cast iron disc is done by the stir die casting method. The experiments were conducted to find out the wear volume, coefficient of wear rate and coefficient of friction. The wear parameters for the commercial brake pad assembly with and without graphene nanoplatelet are compared.

In automotive parts market, there are two classes of commercial brake pad that are original equipment manufacturer (OEM) and aftermarket (Non-OEM spare part). In manufacturing of commercial brake pad materials, the difference of ingredient or concentration used is important because of differences in characteristics and cost. It is well known that the OEM brake pads are more expensive than the Non-OEM brake pads. In this study, the OEM and the Non-OEM of passenger car brake pad were evaluated in order to obtain a comparison of friction characteristics, composition, and microstructure between them. The OEM and the Non-OEM brake pad were purchased, cut out to form specimen, and then evaluated to obtain material characteristics. Specimens were subjected to friction testing using pin on disc machine and microstructure examinations. The results show that the OEM brake pad material has lower and more stable in coefficient of friction than the Non-OEM brake pad material. The OEM brake pad material also has more wear resistance than the Non-OEM brake pad material. Examinations using SEM/EDS show that the OEM brake pad material contains metallic fillers that are Cu and Fe, on the other hand, the Non-OEM brake pad material does not contain metallic filler. The Non-OEM brake pad material uses asbestos as reinforcement.

<p><em>Brake pad is one of the components of a motor vehicle which is served to slow or stop the rate of vehicle. The brake pad of automotive vehicle on the market is divided into three types that are an OEM (original equipment manufacturer), OES (original equipment spare parts) and AM (aftermarket). The brake pad operates under various conditions of dry or wet sliding. The majority of researchers investigated brake pad characteristic on dry sliding. Studies of wet braking behavior are rare in the tribology literature. Therefore, this research performed testing of friction characteristics of dry and wet sliding by using brake pad type OES and AM on a passenger vehicle. Each brake pad tested using the machine pin on disc tribometer type and observed using SEM. The result showed that the brake pad type OES has a good stability on testing dry sliding and wet sliding. In addition, passenger type brake pad OES has specific wear low so more durable in used. Meanwhile the results of SEM showed that the friction layer were not formed during wet sliding.</em><em></em></p>

Friction materials are composed of numerous ingredients which differ from nature and particles size. Each ingredient has its own impact on the mechanical and tribological behavior of the material. Brass ingredients have a great impact on the thermal gradient dissipation in the sliding contact between disc and brake pad material. In this research, the influence of different sizes and forms of brass ingredient was studied on the friction material behavior. The physical (density), mechanical (yield strength, young module) and thermal (thermal conductivity and specific heat) properties of the considered composites were characterized. Results proves that only physical and mechanical properties are sensitive to the changes in size and form of brass particles. The tribological behavior of the brake friction materials was also assessed using a pin-on-disc tribometer. The results show that bigger brass particles and their elongated shape allows it to be well embedded on the pad surface during braking application, and thus decreased wear rate . In contrast, the smaller particle decrease the friction stability and it rounded shape increase wear of the material since it tearing from the surface by abrasive wear.
