There is another thread on this, but no one posted an audio file. I've been noticing this noise in the last 2 weeks and it's happening all the time now. when the brakes are applied while the engine is at low speeds or idle (may occur all the time, but can't tell due to road noise) there comes a robotic servo noise that will continue for 2-3 seconds even if I take my foot off the brake. It happens EVERY time i put pressure on the brake pedal and if I pump the pedal, I can get the noise to continue on forever.
I'm at just under 45k and i've only heard this noise in the last few weeks so it isn't "something these cars do". It's very noticeable inside the cabin with windows rolled up and even when music is playing (low volume).
Ideas? Maybe vacuum issue or low fluid? I haven't investigated as of yet.

Have to turn the volume up.
