well, break fading usually means breaking performance decreases (breaking distance increases) with the same amount of force applied on the pedal. If you mean that the break pedal seems to retract further away from your foot and becomes softer sort of? I think that is normal. When you just start to drive, the pedals and steering is usually less softer than after things warm up.
