All brake pads are metallic bronze washed pads contain copper, tin, graphite and other metallic elements with nonferrous filaments. The high-density built material results in consistent friction across a full range of operating temperatures and reduces brake fade at high temperatures. Provides instant braking performance in wet or muddy conditions with exceptional stability in all temperatures. The sintered metal brake pads are proven to last longer than carbon, Kevlar, semi-metallic and other organic brake pads.
