Tapping noise at front end wheel / joint area.

[KC272]

• Hi, Let me start with saying I am new to this site ( Just Signed up ), so I apologise if this subject has been dealt with already.
  I have an Audi A4 S Line ( B7 ) and it has a really annoying tapping coming from the both front Wheel / Joint area of my car. These seams to be quite a common fault as I have searched on line, but no one seams to have a definite solution.
  
  I have changed all of the joints which needed changing and even had new pads and discs fitted, but the noise is just getting gradually worse. It is now embarrassing to drive. PLEASE HELP!
  If any of you know of the solution, please let me know. Alternatively, if anyone knows where I can buy a cheap balaclava that may be an option.

• On Saturday, I changed the rubber boots that the calliper guide pins slide on, as a mechanic I met suggested that's what it could be. I also cleaned all 10 years of crap from all the areas that the pads slide across and greased everything back up, but it made no difference. I fact it has probably made it worse, now everything is clean and moving more freely. I did notice there is a retaining spring misses off of the outer side of the calliper. I will be getting & fitting as soon as I can get back down to Audi.
  The tapping is almost defiantly coming from the brakes / calliper, as the noise stops when I press the bake peddle, even just ever so slightly.
