The most prominent feature of this series of brake pads is its copper-free formula. Traditional brake pads often contain copper elements, which produce copper dust during braking, causing environmental pollution. The Nutech Environmental Copper-Free Series Brake Pads use new environmentally friendly materials to replace copper, effectively reducing heavy metal pollution and meeting increasingly stringent environmental standards. Choosing these brake pads is contributing to green travel and protecting the environment. The environmentally friendly copper-free products use new materials that replace copper, combined with high-temperature-resistant materials such as carbon fiber, are ahead of environmental protection, free of asbestos and other toxic substances, and contain no copper. Their performance is similar to NAO formulas, with stable friction coefficients, excellent speed sensitivity performance, no reduction in high-temperature braking efficiency, and excellent resistance to fade. Comfortable braking without noise. Specifications: Customizable.
