Recently, research-development studies conducted for the production of organic brake pads because of the usage of asbestos in brake pads have negative effects on human health and the environment. This study aims to develop to non-asbestos high performance brake pads. Twenty-four types of different dusts in commercial brake pads have utilized as fillers, reinforcements, binders, abrasives and friction modifiers in mixture of organic brake pads produced. In this study, seventeen of these friction dusts were used to develop to organic brake pads. The 3.5 wt.% and 7 wt.% content of hazelnut and walnut as friction modifier materials were replaced with petrocoke dust eco-friendly. The performance of brake pads was determined by microstructural examinations, oil absorption and dimensional stability, and hardness of brake pads. The results indicated that the brake pads produced with organic dusts such as hazelnut and walnut shells can replaced with petrocoke dust. From this, it can be concluded that new type brake pads of non-asbestos organic-based dusts can be effectively used as a replacement for asbestos and performance in brake pad production.
