Four Products has developed an innovative and economical solution to reduce brake temperatures and increase brake component lifetimes. A CoolShim™ is a "drop-in" part that fits between the brake pad and the caliper piston. It conducts heat from the caliper to a heat sink located externally to the brake caliper through a high thermal conductivity dual metal composite developed by Four Products specifically for the extreme thermal conditions found in high performance brake systems.
