I’ve got a small break fluid leak that I’ve known about for a while now but needs fixing. It’s coming from the nsf and the fluid is leaking all over my anti roll bar. I did some reading of other posts and it sounds it’s one of the clutch lines not a brake line. I’ve gone under and done a little exploring and I’m pretty sure it’s the clutch but I have no idea what I’m looking at. I’ve attached some photos and it appears the leak is coming from the joint above the black circular thing (no idea what it’s called or what it does sorry) Anyone know what this part is called so I can order it and get it replaced? Thanks
