Clucking Noise when brakes are applied.

maybe a couple of pbs. 1) Bushings are going.(Not the Lower Control Arm Bushings) 2) Lower Control Arms/bushings going. (check you tube) If it is pulsating when the brakes are applied it maybe a combination of Brakes and LCA's. So I replaced the brakes(Did them myself, The lower control arms and other bushings that name slips my memory right now I had done at a shop.
