just noticed a slight brake leak on my fronts. From what I can tell it is occurring in the coupling I have circled. There's no sir in the line and brakes are solid. Might have occurred during my bar swap, but don't recall anything happening that would contribute. I have new lines on the way anyway, but is there a good option to saving the leak in the meantime?
Wouldn't try to salvage it since you have a new line in route. Brakes are 1 of those things you dont want to J-rig. Plus brake fluid on your tank or fender leads to some choice words
If you had your lever hanging for anytime during bar swap it is possible that fluid got to the wrong side of the gasket and is now working it's way out. It happened to me. Just pull the cover and clean the gasket off with alcohol dry it good and replace. No more leak.
