No, I have not tried anything to fix the problem yet. I just took a few moments to find where the leak was but i did not have time to work on it yet. I'm sure that the two lower lines are connected to the MC via two separate Proportioning valves for the rear drum brakes.
The leak is right around where the back (of the two) Proportioning valve screws into the MC. I'll try to tighten it tonight.
It just seems weird to me that it could be loose?
