Use some Ti shields between the backing plate and the piston. It will likely solve most if not all of your problem. I've been using them for 10 years on various cars with great success (reducing heat transfer to the piston, shielding (from a radiation heat transfer standpoint) the dust boots from "seeing" the hot pad backing plate surface, etc. They are especially effective as your pad thickness wears down since the pad material is a highly effective insulator, so as the pad thickness decreases the backing plate temperature (and therefore piston temperature) goes up...a lot by the time the pads are thin.
