Ive just installed a new brake line...but bake brake still leaking..

There is no way to post on the internet the correct way to replace a brake line!!.. Just don't cross thread the fittings... Try YouTube for a video and watch it being done... After you've done it 'several' times... No sweat !!

Special tools are required - leave brakes lines to the professionals please. Includes double flaring etc ... do not use the ferrelled unions as they are not safe and actually illegal to use in some states. Take care
