I too, am perplexed by the long pedal travel in these Crossfire's. Mine is a NA but it just seems like the pedal has to go a long way in before the brakes stop the car. Like others, I have bled the system three times, had new rotors and pads installed, and put on the stainless steel wrapped brake lines. New fluid of course, on all three bleedings. My regular car is a Jeep Charokee that stops firmly with just barely touching the brake pedal. It's tough going from the Jeep to the XF. It's scary sometimes. You wonder if the XF is going to stop in time. Anyway, hope we can find a solution somewhere.
Thanks for the diagram and the comments.

My troubles preceded the installation of the oil catch can. The power brake has a reservoir that holds the vacuum from dropping as the engine revs fall, the reservoir has a one-way check valve on it.
It takes a couple of brake applications after the engine has stopped to deplete the so-called vacuum, it really is not a vacuum just lower air pressure. The car can pull nowhere near a vacuum, but we call it a vacuum anyway. Even with the car idling the vacuum is enough to assist the braking. If the catch can restricted the vacuum it would not affect the other vacuum lines.
