Front-end clicking/knocking when braking - 2006 B6 Saloon

[jordy_wd]

Hello,

Sorry, but I have another "what's that noise?" thread. It's a knocking/clicking on the front-end of the car under braking, generally when I'm reversing the car into the driveway. It happens mainly when I drive up my street, swing to the left, and then reverse the car back and to the right into my driveway.

I think the noise could be brake pads moving around, but I'm not really sure of how to fix the problem. I've changed both my brake pads and discs and there's been no change. I also thought it could've been the hydraulic cable ratting against the chassis leg but I sorted that out and the noise is still there. I was thinking fuel lines rattling also, but again the noise sounds like it's coming from the brakes.

Any help is greatly appreciated.
