Steel braided brake lines can help give a stiffer pedal but only very slightly (unless you have very bad lines on the car). New stock hoses would help that, too.

Steel braided lines (made for brake systems) usually have Teflon in place of rubber, which expands less, but most people wouldn't feel that, and it would not shorten braking differences. The steel braid is mostly for protecting the hoses from being cut or chafed.
