Replacement semi-metallic front brake pads for models manufactured 1969 - 1973.
Semi-metallic: This formula, containing about 30 to 65 percent metal, typically includes chopped steel wool or wire, iron powder, copper or graphite mixed with inorganic fillers, and friction modifiers that bond all the ingredients together. These pads are more durable and have excellent heat transfer, but also wear down rotors faster, have intrusive noise characteristics, and may not perform as well under low-temperature conditions.
Organic: Sometimes listed as organic or NAO, this type of pad is made by mixing nonasbestos fibers, such as glass, rubber, carbon, and Kevlar, with filler materials and high-temperature resins. These pads are softer and create less noise, but they wear faster and create more dust.
