This was a problem mentioned on a Mercedes forum, the seal between the booster and the master cylinder was left off and the oil was sucked into the MC when the MC cylinder seals failed. I do not have any fluid loss so I have discounted this, thanks for the idea though.

I cannot simulate this, thanks again for the idea.

I took the car to my local Chrysler and asked about getting the ABS system bled as it has to be cycled with the computer attached to the car. The system is then re bled normally. I was told they do not have too many Crossfires to work on so the manager was going to phone Chrysler and get some hints. We shall see what happens there.

I am going to look into the possibility that a piston is a bit tight and the seal is not retracting the piston when the pressure is released. I cannot see this causing my problem but I think that I can hear a pad rubbing for a while after the pedal is released.

I am also going to put the OEM pads back on, I know what they sound and feel like from my first Crossfire.
