So this appeares to be a line chafing issue and not a corrosion issue correct? Is this a metal line or a flexible rubber line. Is this line for the front or rear brakes. It is un-likely a chaffing issue could have been agrivated to failure in just two weeks. However chaffing is something that is usually caused by improper assembly and lack of attention to detail. It is this kind of issue that is the main reason I do my own service.
