Surely if the damper assembly is locked up or its action is jerky that's down to the adjustment being over tight or there being high spots on the friction material. If the discs are greased then you will need even more tension to get the same damping effect, surely? My understanding was that the wood (or lignum) discs should be lighly sanded to remove any glazing and re-assembled dry,(apart from the pivot bush). The damper is a friction assembly just the same as a drum brake. You wouldn't advocate greasing a brake shoe to make it more effective, or at least I hope not.
