Find a repair shop that will cut out the bad section of metal brake line and insert a new section. Some shops will want to replace the whole brake line, but that can be more expensive and not needed in many cases. You'll pay $300 or so depending on the location of the leak.
Even though an axle seal is not a very expensive part, the repair cost may vary from $150 to $650, depending on the complexity. For example, in the Ford Escape mentioned above, a leaking axle seal is recommended to be replaced as a kit with an axle bushing and inner CV joint; this may cost up to $600-$650.
