Can't stop new caliper brake line leaking. Why?

[Timbuick]

Guys, with my onggoing bake saga...
I fitted new oversize gbody calipers tonight. No problem there.
I then bolted up the brake line and it won't stop leaking.I have tried both the original bolt and a new one that came with my calipers.

I cannot stop the brake line leaking where it joins the caliper. Why?

did you replace the copper sealing washers on either side of the banjo fitting?

Hi Dr,After posting I went out and took a second look. This time I fitted the two washers as you say, one on the banjo/brake nut, the other between the caliper and the brake line.It doesn't leak now
Somethings you have to know.Thanks, anyway!
