Hello, I am just changing the axle on my A3 8P and I noticed that parts of the two brake lines that go forward are rusty. I would like to patch this spot. Should I re-name this spot with a new brake line, blot it and insert the ones with connectors again. I just ask myself how do I stop the brake fluid from running from the separated pipe end in the meantime? I want to prevent that I totally get the brake device. defiled or the ABS unit runs empty.
