Don't be tempted to lubricate the bobbins in any way, anything you use will be heading straight for the friction area of the disc at speed!
The discs and pads must be cleaned as well as possible with clutch and brake cleaner before trying to condition them with the heavy braking exercise.
The secret is to give the brake a firm, even, LONG application to get it warm and apply plenty of friction. A good head of speed helps lengthen the braking time. Let the brakes off gently as speed fades and try again. It's important not to come squealing to a halt as the idea is to warm the discs evenly and let them cool evenly with the pads off and the wheel still turning.
Unfortunately this method will not do any good if your discs are actually warped, the only way to find that out is with a dial gauge.
If your brakes are juddering I suspect that it is warped disc(s) as the surface conditioning syndrome tends to manifest at walking speed in the final yards of braking to a halt, as a sort of on/off or pulsing feeling.
Definitely worth trying an Italian tune up though...
