Do you feel it in the pedal when braking?
It could be your tie rods, jack the car up in the front, enough to get the wheels off the ground, and then tug on each tire from 3-9 o'clock and see if you hear the noise.
Another thing, it could be warped, or irregularly worn brake rotors, I had a problem where seized caliper pins caused the rotors to warp a bit, I also had bad inner tie rods on both sides, due to hitting a big ditch that sheared my rack bolts, and due to not knowing I was supposed to grease them once and a while.
The lower control arm ball joints could be bad, but I'd check the tie rods first.
