Now that pad replacement, which would not have cost much, has become a pad and rotors replacement. Other reasons also exist for you to get brakes checked. Brake lines can go, and this is very dangerous if not fixed right away. No one under any circumstances should be driving with a broken brake line, even if it is just the back brakes. If you need to replace the brake line soon, the person checking your brakes will say so.
