I am replacing the calipers on my car. After pumping the old fluid out, we realized the soft lines needed repair (they were fine before). Now, there is a link under the car that appears to be coming from the master cylinder:

The dark areas are wet with brake fluid.

Here is a closeup of the master cylinder. The dark areas are wet. The only spot that is not wet (yet) is the lighter area on the lower left:

I have checked the reservoir at the top and it is fine. The fluid is coming from somewhere down here.

Please advise!

Thanks!
