Copper grease on sliding brake parts?

Hi all, I was talking to a mate earlier who saw on the web somewhere about not using the likes of copper grease on the sliding parts of (disk) brake assemblies, like where the pad slides in the caliper etc? The reason given was that the brake dust mixes with the grease and forms a hard material that then resists the free movement of the pad? I have typically added a small smear of copper grease to such parts and rubber grease for any pins running in rubber boots and can't say I've ever had an issue? Cheers, T i m
