Hello, 2024 I changed the brake line from the ABS hydraulic unit to the rear to the two wheel brake cylinders on my 451 from 2007. Since yesterday the little one has again incontinence and it drips brake fluid at the bottom left, also the container is empty and the brakes at the rear are cold. The question is, which line is now gammelted. Outside it is cold, so I would like to order new lines in advance and not like to put myself under twice. any of you have an overview of the product numbers of the different brake lines or even an explosion drawing to locate the defect in this way? Thank you!!!
