The brake system is a mechanism that allows the vehicle to slow down and remain stationary. Most automobiles uses either one or both disk brake and drum brake system. These brake system components include the brake pedal, brake lines, brake master cylinder, brake booster, brake calipers, brake rotors/drum, and brake pads. The greatest load in the braking of a vehicle falls both on the discs and pads. The friction caused by braking on these parts results in a large amount of heat transfer and particulate emission. Therefore, studies on the brake system have focused on human health, the environment and the economy, in addition to investigating the operation, performance and wear mechanisms of the system. In this study, researchers, citations, keywords, and trending topics of 1,118 studies on brake pad between 1982 and 2023 were investigated by systematic analysis method using R and VosViewer analysis programs. A brief summary of the most cited papers and their topics is given to help researchers who will conduct studies on brakes. These studies focused on wear and emission issues. Non-exhaust emissions have adverse effects on air, aqueous media, roadways and human health. Therefore, it has become mandatory to limit these small particles, which is why they are included in the Euro 7 emission standard. Due to the limitations on braking, future researchers have been informed about the status of non-exhaust emissions.
