Did you bleed the brake system after you install the brake lines?
Point being, if you didn't bleed them, then the brake pedal would still go to the floor. If you didn't bleed them and now the brake pedal is hard, then it is something awry in the hose replacement process. Have the mechanic to recheck his work.
Meanwhile, raise the front wheels of the vehicle, (secure the vehicle on jackstands or vehicle lift), crank the engine and pump the brake pedal about 10 times. With the vehicle still running, try to turn each front wheel by hand to see if they spin freely.
If not, the "stuck" tire is the one with the brake problem.
If they both turn freely, have a partner to apply the brakes, now try turning the wheel by hand. If one tire stills turns, this is the one with the brake problem.
Repeat this "test" on the rear wheels as well.
Post your results here please.
