To be honest my gut feeling is that these discs are actually warped as Dingdong says it gets worse when they are hot, and a previous effort to straighten them has been made.

By all means give the Italian tune up a try, but take care as it will most likely make them worse if they are warped. I think you will notice this at the end of the long hard brake as you let the pressure off the lever, in the form of the pulsing turning into shuddering.
If that happens ride carefully home and order the new discs. If you get lucky send me a packet of chocolate Hobnobs..
