Why is there a pumping feeling/noise under the brake pedal ?

What is your question?

when going over 10 mph, there is a pumping feeling and noise (which is only heard inside the car) in the brake pedal. I can feel it under my foot. What could cause that? The brakes have been replaced, ABS sensor cleaned and replaced. Brakes work great. No noise is heard from outside the car. Just the pumping feeling in the brake pedal and noise inside.
