Hitachi ex17-2 swing brake

I have a problem with my swing brake or -motor. It can swing the house clockwise but only veeery slowly counterclockwise. I am able to push the boom manually clockwise but counterclockwise the swing brake works as it should. What is wrong?

    No help om this one? :-( I thought it would be easy to figure out for you guys. Did some testing today swapping the hoses at the joystick. Same problems as before with the counterclockwise swing and the clockwise swing brake. Swing is so weak I can stop the boom by pushing it :-/ followed the hoses to the main block but have no idear what to try next :-/
