replacing brake lines

I just helped a friend replace her right rear brake steel brake line on her
93 caravan. I tried to get a factory piece from chrysler but they said that
I have to bend the lines.

So instead of paying the dealership big money for their brake lines I just
went to the local auto supply store and picked up a 3/16 thread double
flared 30" steel line and installed it.

My question is: The line that i bent doesn't bend exactly like the line I
took out but does follow the same general path. I made sure I bent the
lines in a gentle curving fashion and there aren't any kinks. How do I know
that these lines are reliable as the factory ones? My bends are far from
being perfect but I think they will do the job. There was a clip holding
the old line to the axle but I didn't re-install it on the new line b/c I
figured that the steel clip will rub on the steel line thus eventually
puncturing the line. The factory line had the clip b/c the old line also
had a spring like winding around it to protect it.

Also the replacement line has the screw fittings on each end but the two are
different lengths of threads. I screwed the longer threads into the rubber
line for the rear brakes (it didn't really screw in a whole lot but I didn't
see any leaks and the threads were screwed all the way in) and the shorter
threaded end into the wheel cylinder. In both instances when the screw in
fittings were completed tightened there were threads still exposed on both
ends of the line.

From what i've said does it sound like I installed these lines correctly?
The brakes work just fine and I didn't see any leaks and i even stomped on
the brake pedal to make sure it didn't sink to the floor.

I don't want my friend to crash her van b/c I made some mistake along the
way...

thanks
