These pins would rust up, solidly enough that the pad really was not moving much, despite heavy pedal pressure. And the pads did not hang-up on the rotor either. But the limited motion of the pads resulted in a springy , soft, depressed pedal. I had 2 shops look at it, bleed everything, to no avail. It was only when I went in to replace the rotors and pads, out of desperation, that I discovered the cause. BUT, since you have determined that the pads do move freeely, this does not seem to be your problem. I would be looking at the rubber hoses, expanding. Good Luck with that beautiful car.

Thanks Paul, I did listen to you and actaully stripped all the pads out of the calipers, cleaned and checked everything, and then refitted. I got really desperate to fix it (this has been going on for three weeks now) so got on the phone and rang around ten or so brake shops. I had a list of all the things people had suggested on this formum and ran it past all the specialists.
One thing I learnt from this excercise is that even when you get advice from the 'experts' that the level of experience and advice varies massivley.
I had one guy 100% convinced it was the brake booster even though, as Aurthur has pointed out, its a ridgid fixed coupling betwen the pedal and the master. He wanted me to bring it in for replacment at a cost of 700 dolars. That would have been tipping money down a hole.
