Brake discs and pads replacement after just two years?

I have been advised that my two year old Subaru Forester's two year service that the brake discs and pads are in need of renewing as the discs are pitted. I have never had this problem with other motors. Can you advise me if this is acceptable or could there be a parts fault?
Discs have been softer and pads harder with metallic content ever since asbestos was banned from brake pad material. That's why the discs are more prone to corrosion.
