Hearing this ONE-Click sound coming to stop..brake issue?

[ES_TRADER]

Occasionally, when I am driving in a tight space area or parking the car, I hear this sound that sounds like its coming from the outside and it is just a fairly audible CLICK sound but happens ONLY when I push the brakes a bit hard and the car stops abruptly. the sound appears the moment the car makes the abrupt stop...

It only happens coming to a stop from very slow speeds and i dont think ive ever heard it on public roads..maybe it happens but road noise muffles it out...

Ill give an example since this may be hard to picture...happens when im trying to get as close as possible to the wall in front of me, obviously without hitting it, so im going very slow, but sometimes i go a bit too fast and i quickly press the brake..car stops immediately, and i hear a "Click" from the outside.

Anyway, has anyone ever experienced this? you would really have to listen for it and the only way is if the music is on low and windows slightly down.

Is this some sort of problem with my brakes?

just wondering if its an issue i should bring into the dealer. thanks for the input
