HAGEN, the Brake Pad for Foreign Vehicles Dust-free Method It minimizes the risk of disc thinning caused by repeated braking or scoring (i.e., the phenomenon of discs being torn down in the shape of a record disc), and prevents worn-out disc particles from becoming stuck on vehicle wheels to ensure the maintenance of clean wheels. OE Technology-based, the Most Optimized Product With excellent and effective stability, the product maintains a consistent friction coefficient regardless of braking conditions, i.e. low speed or high speed, and allows for more economic benefits over other products. Low-noise Friction Method This product significantly prevents the high-pitched squealing noise and the low-pitched growling noise that occur upon braking. Environmentally-friendly Product The four most harmful heavy metals for human body (lead, cadmium, mercury, and chromium-6) are not used. Instead of using the cancer-causing agent asbestos, expensive but safe materials like aramid fiber and mineral fiber are used for this environmentally-friendly product.
