Knocking sound when braking lightly

[Acheron]

It never used to do this, but my S3 has for the last week started knocking from the front when I brake lightly. Sometimes this does not occur until the pitch of the road changes again and the faster I go the quicker the series of knocks (usually around 2 to 5 seperate knocks) when I brake. These knocks can be felt through the brake pedal as well.

Taking the car along the highway earlier and cruising above 100km/h I can actually feel something touching somewhere lightly, again through the brake pedal and there is definitely a metallic friction noise somewhere. The front pads and discs were replaced a month ago.

Ah ***. Something told me to go have a look at my wheel nuts since the noise started shortly after putting my wheels back on (after Plasti-dip'ing them).

Front passenger side 4 out of 5 nuts were loose. Not sure if they worked themselves loose or if they were never tight enough to start with. Checked the other wheels and those were still good.

...either way, the noise is gone!

I have been experiencing the same recently and put it down to maybe needing new brake pads and discs better check mine when I get home then I think! Thanks for sharing!
