    When stationary and lightly pressing on the brakes there is an air sound that doesn't seem to be going away. Anyone experience something like this? Brakes work fine but it's pretty annoying.

    what are you driving? it sounds like a prius brake accumulator. pretty normal, did you just get it, or is it a different car?

    Very glad for the video because that was an electric motor whir, not a hiss.

    This is in a 2013 Prius that I have had for a few years. The sound at 4 and 19 seconds is normal and I believe is what builds pressure in the brake system. The other sound that is present throughout the whole video is the annoying one I'm talking about. To me it is more of an air hiss sound than buzzing.

    If that is the sound you hear throughout the whole video, then yes. To me it sounds more like small burst of air being released.

    definitely not normal, but i don't recall ever hearing it before

    if the actuator is leaking, you usually hear the buzzing of the pump more often and for longer periods of time
