No amount of bleeding will fix it. Just have to put a few hundred miles on the car and get new seals broken in.

Just another thought.

If it is serviced with non ATE seals it may never work correctly. The cheap seals have WAY too much seal retraction. I saw a fresh rebuild with over 2500 miles on it never get over the seal problem.

Insist on ATW in the blue box.
