Oh the fun of breaked brake lines..! :frustrated:white200break said:
Not all that uncommon to happen, if the rubber to hard line is really rusted..
Probably the easiest way to deal with that is find out the length of the hard line you need (the audi parts master often mentions line length), and go to your local parts store, and get a premade line (already flared, with the metric fitttings already on) that's a bit longer than the line you need.
Don't worry about that "bit longer", as you can easily waste some 'distance' when installing (hard to stretch a bit longer though.. :-( ).
In my mind, premade is well worth the price, as it means you don't have to screw around trying to flare tubing..!
