Richard regarding your last question it was a bit ambivalent talking with the Morgan garage.
On one hand they claimed now to mount pre used discs which had been smoothed after first use to install them again with the goal of a longer lasting good behave due to material stabilisation which could mean the problem is known and common. (but it did not help in my case).
On the other hand they accused me a bit and were asking if 1) I drive like Rambo or 2) if I make a car wash and then drive her wet into the garage (which I don't do). Their theory is that in this case between the brake pad and the disc some water could be stored and softens the disc at this area causing the wobble because the disc widens.
