If Audis are anything like VWs in this regard (and I don't see why they
shouldn't be) then the brake line flares are metric ISO flares, not
double flares.  This takes a special tool (sometimes called a bubble
flaring tool.)  Although a double flare may not leak, it will not be
reliable as it does not mate properly with the fitting.
