My car had the exact same combination before I started messing with it, and indeed it's true that all was smooth and happy. Once you find the problem it will be a joy to drive.

Yahoo! Success at last.

With the tubes I was able to flush out the air. It still took many pumps. I also started pinching the hose (especially on the rear reservoir) before letting the piston...

John - The 1/8" stroke deal is because the outlet ports are plugged off. With tubes connected like you have there, you get a full stroke and the fluid is pumped out through the outlet ports and back...

My concern is that the stroke is still 1/2". The instructions say that when it is bled it should be 1/8". The link referenced above says the same thing.
