I think you are going to have to use another word other than friction to describe it.
Does the pedal feel stiff, hard to press?
Does the pedal vibrate as you press it? Does it vibrate if you just rest your foot on it without pushing down further?
Does the pedal hum or rattle?
Does the pedal turn purple and play music from the 80s that you don't like?
Give us something other than the word "friction".
