2001 Front Brake Question Please Help!!

My front Right wheel has a leak. But here is the thing. I have located the brake line that goes to the caliper near the rear. But there is another line that goes to the front part of the disc. This is where the leak is. I have looked for brake diagrams all over the net to figure this one out so I hope someone out there knows what line this is or knows of a site that can help....

Many thanks in advance..
