    Possible brake booster problem ?

    I noticed a weird vibration and noise that happens when i step on the brake sometimes. I step on it and it feels like its rubbing against something and i can hear a vibration but my braking performance is not being affected.

    Any ideas ?

    Do you FEEL any vibration? Does the steering wheel shake when braking?

          Vibration like the pedal was pushing back and forth, or vibration like your cell phone may be vibrating in your foot? Lol.

          Is it happening when you step hard on the pedal? Does it make a noise at all?

            Any grinding noises? Does the brake pedal vibrate? Does the steering wheel vibrate?
            There could be any number of problems:
            warped rotors
            bad tires
            suspension issue

            (POST EDIT)
            What does the noise sound like and where is it coming from?

              well no joke but it sounds like when a whale makes those weird sounds or like the cellphone one because i can hear it and feel it. Yesterday it did it but not today. No steering wheel shake at all.

              Better yet ,, close your mouth and say HUM real quick. Like for one second. The vibration feels like that too on the pedal. Just a sudden HUM.

                  Do you have abs? If so sounds kinda like what the abs pump sounds like when activated

                      here is an old trick to try to isolate it

                      when you are by yourself on a road ,no other cars around, try stopping using the e-brake only that should tell you if its in the front or rear as the e-brake uses the rear rotors/pads only

                        It could be the ABS pump cycling. The ABS needs to be flushed occasionally and it's something that has to be done by Honda. Any ABS light on the dash?
