Strange knocking sound coming from front left of car when braking

Remove this ad
Just today, my cadillac cts 05 with about 50k miles was on the road, and i start to hear this "knocking" sound when i start breaking. We just bought it used and the car drove and sounded fine right up until today.

The knocking goes away once your at a full stop or when you are accelerating or going at a constant speed. It only happens when you start to break and it doesnt start immediately. It takes a good 10 minutes of driving before this issue kicks in. Does anyone have any idea what this could be? or a solution?
