What does original equipment manufacturer mean? For Sangsin Brake it means that automakers prefer to have Sangsin brake pads factory installed on their brand-new vehicles. Since 1979, Sangsin Brake has supplied foreign nameplates with top-quality brake pads. In 2008, Sangsin began supplying domestic nameplates, starting with Tesla. As we continue to expand our operations, product portfolio, and state-of-the-art Research & Development center, our mission is to ensure Sangsin OEM brake pads are made with the highest quality of performance friction materials — and made available the world over.
