I think you will find they are insulators not conductors of heat (heat
sinks). As the material wears down, heat is transmitted to the backing
plates and calipers faster, since the thickness of the insulator is less.
Properly, the heat should be confined ot the disk where it is radiated
fastest. The caliper and brake cylinders should be insulated as well as
possible for best performance.
There were experiments with ceramic bases on pads for insulation before
carbon fibre became popular.
