The little OEM iron brake valve that you did not replace can be the source of many varied problems. If you do not have one, get the brass one to replace it. The iron valve can rust into permanent position and appear to be okay, but the internal valve will not slide and do it's job. At least push the pin on the front of the valve and see if it moves. No movement, it's toast.
Your description of the problem sounds like air in the lines.
