how to get the air out of the brake line of a 2000 chrysler concorde se on 2000 Chrysler Concorde

i replaced the brake pads on my car and my brake pedal is down to the floor

If you opened the bleeder screw to push caliper pistons back in then you need to bleed the affected brakes, the ones you worked on. IF you did not open the bleeder then pumping the pedal should be all you need to do.
