Did you inspect and find out why the pedal to the floor happened? Did it happen all at once? Did you just start throwing parts at it without knowing what is wrong? Answer the questions then maybe we can help. What is the detailed story in order of occurance?

Look at brake lines, flexible hoses ect.. Brakes are critical.
