They should have been replaced in 2011!

Rubber brake lines should be replaced every four years as a matter of course as they degrade from the inside. They might look nice on the outside, but the could be a right old mess inside with fragments of rubber contaminating your fluid. They also become porous to gases (and water vapour) over time.

Replace them and if nothing else you'll experience greater peace of mind. New lines will improve the feel of the brakes slightly and your fluid will stay clean and free of moisture for longer. Braided lines last longer too.
