I finally got my 12C to a track--4 sessions on two days. In the first session the brakes required a good deal of effort and were difficult to control. And heavy braking made the car sway from side-to-side. In the second session, the brakes were lighter and easier to control. But the sway was still there. In the third and forth sessions, the sway was gone.

Perhaps others have noticed similar behavior. In any case, the 12C seems to need more to properly seat its pads than gentle use.

I wasn't aware that carbon-ceramic/CCM brakes needed a bedding-in procedure post-delivery (assumed bench-testing & pre-delivery runs would have it set out of the box) . There are all sorts of anecdotal opines w/ regards to this on the inter-webz. Perhaps, the MP4-12C's carbon-brakes needed some modulating?

Anywayz... this seemed like the best procedure I came across: Bed-in PCCB

Lastly, perhaps Woking can send you these that they have sitting on the shelf! :D

My guess is that it is the driver that beds into the brakes. The car does sway under ABS.
