I'm seeing more brake rotors advertised as partially-coated or semi-coated where the coating is limited to the non-friction surfaces of the rotor. The friction area of the rotor where the pad makes contact is not coated (or is very lightly coated) enabling new pads to bed a little faster.
I'm wondering if this partial coating is also a solution to a problem where ceramic pads get gunked up when bedding a fully coated rotor? I imagine that semi-metallic pads make quick work of the coating and are not a concern. But what about ceramic pads? Is it unwise to pair them with fully coated rotors?
