I think I have a leak near the master brake cylinder, is this bad, or fixable? Options

[914 RZ-1]

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!

You need to pull the pedal board
Then the rubber seal where the plunger goes into the master cylinder

If it’s we under the rubber. Then replace MC
If it’s dry then it’s the reservoir leaking down the tubes or chassis
Surprisingly. My reservoir cracked and the fluid followed the chassis seam down and leaked the same as yours. However it will be dry under that rubber seal on the MC plunger
