To find where a brake line is leaking, have a friend push the brake pedal and look for the dripping fluid. Hard brake lines are not "repairable". They must be replaced. To replace one, you must obtain from the parts store an appropriately sized steel line (nothing other than steel). Using the proper tools, it must be bent to shape and flared on the ends. Sadly, no one makes pre-fab brake lines for modern cars (affordably). If you want to tackle this project, talk to your local parts professional about the tools and measurements you'll need --before you start the job--. If you're lucky, the rubber hoses are where you'll find your leak.. simple to replace. Either way, don't forget to bleed the system of air before attempting to drive it again.
