Braking noise

I have a VW TDI Golf…and for the past month now i have been getting this very irritating ‘clicking’ noise when i brake. I have just recently had a driver side wishbone replaced too, dont know if that has anything to do with it…but is there anyone out there who can help me in this matter???

Is it in synch with the speed of the wheels?
Is it affected by anything else, like turning or accelerating?

Well you see am not too sure…i dont think its affected whilst am steering or accelerating. Its just a clicking noise every now and then whenever i brake, whether am in first second, third, forth or fifth gear.
