96 Voyager Brakes

I changed the pads and rotors on my 1996 Plymouth Voyager today. The pads were REALLY low, and I had a metal on metal sound. After putting it all back together, I notice that the pedal travels farther than normal, and it doesnt stop like I think it should. I checked the fluid reservoir, and it appears full. Any ideas on why the soft pedal? Any help is greatly appreciated.

Thanks....
