[s-cars] Leaking Banjo Bolt

[Andrew B]

I have a leaking banjo bolt on my new Boxster caliper install....the
passenger side appears fine but the driver's side leaked quite a bit.
I removed the bolt, wiped and reversed the copper washers, but it
stills weeps just enough to be concerning.

Is this something that's likely to go away with a fresh pair of copper
washers in the appropriate size?  It seems like everything is the
right size and length, and I'm not comfortable putting any more torque
on the wrench.  I'm guessing a piece of dirt got in there or maybe
just an inferior crush washer was used, but I want to be prepared if
it's something more serious.

My lines are from paragon, but the banjo bolts are from another supplier.

FWIW the difference between g60s and the new boxsters are night and day.
