Haven't heard of copper grease being used on brakes... May I suggest looking more closely at the mount bolts & sliders where the caliper bolts to the fork. If the slider bolts are seizing, the caliper will not release the applied pressure and cause the binding action you spoke of... This may save you a caliper overhaul...
Clean the slider bolts, mount points and holes thoroughly. Apply what we call "white grease" also known as "brake grease" to the parts. Be sure to keep the grease away from the pads & rotors, and apply it sparingly. Inspect the rubber seals for deterioration, cracks or tears and replace them if needed. Re-install the calipers and if they still bind up, then go for an overhaul... I've never used any type of grease when overhauling calipers, just brake fluid (dot 4).
