How do brake heat shields increase pad life?

Where our heat shields provide increased pad life is in reducing the amount of heat that gets transferred to the caliper components as the pad wears down. In addition to acting as a friction material, brake pads also provide insulating properties; not nearly as good as our titanium on a mm per mm basis, but even just putting a physical distance between the pad/rotor interface will cause the heat to transfer more slowly into the caliper. When your brake pads wear down, you get more heat transfer into your caliper. Many racers throw away half-used pads because of this (or store them in boxes on the shelf), something that the brake pad manufacturers don't mind at all. Our product lets you run the pads down to a lower thickness before the heat transfer becomes excessive.
