Brazilian Dodge Dart 76 (similar to 69 usa)

yesterday I got brakes! I did not bleed brake system yet. What I did? I'm opening bleeders and letting oil leaving brake system. In this process, oil brings some air bubbles with it.
I know I still have to bleed properly. But I was alone. My wife promised help me today.

Bad news are: two connections leaked a very little oil during the night. In fact, only a drop of oil on each one. I was able to tight them a bit more.
Hope no more oil drop leaks!

Ps: the connections with this little leak problem are the "rear output" and "passenger side output" connections of brake splitter. Inputs are ok.. calipers connections are ok. rear splitter is ok... and rear drum brakes are ok.
