Pictures of my scratched rotors...
 

Not the greatest pics. The scratches are deeper than they look, though.

Car's with my mechanic now. Assessing the damage.

Dunno if he can resurface them. Kinda hoping they're done. Good excuse to get the A8 upgrade...=)

I've got the same issue...
 

fronts only, apparently. What exactly is the problem? And could I swing an upgrade? =)

Not sure what it is yet.
 

Could be worn out pads, could be a loose part. No idea. Waiting for mechanic's phone call.

Is your rotor making a grinding noise? That's how I noticed my scratches...

I'll let you know once I find out.

Noticed it when swapping wheels from 18s to 15s
 

Immediately afterwards I got a metal-to-metal grinding noise whenever I turned the wheel. I swapped the 15s for 16s, and the sound is still there, albeit less frequently. Mostly from the front driver's side.

Sometimes when braking, I also get an awful grinding noise... usually as I approach a stop on less-than-smooth roads.

That's usually a sign of worn out pads. If the scratch is not deep enough, the rotors can be
 

resurfaced. Jack the car up and spin the wheel.

Do you hear a metal to metal noise the the wheel doesn't spin freely? If so, there may be some foreign material lodged in between the pad and the rotor - or some clip came out and is stuck in between them.

If no noise, then maybe that foreign material had been chewed away

else if, the pads are worn ;)

Either way, you need to have your brakes worked on. I can't remember if it is stamped on the AUdi rotors, but most rotors have a minimum thickness in millimeters as a guide for the brake guy turning the rotors. He'll know if he has to grind too much material and you'll need to get new ones. Recently midas charged us $20 to turn 2 rotors. I used to do it when I worked in a shop.

bah... these are are scratched rotors :-)
 

Lessons learned: use track pads and take an extra set of pads to the track.

OUCH!

Mechanic called and said that rotor's hosed. Time for big brakes! Woo-hoo!

Scratched mine once. I put the brake pads in wrong...Doh!

stopped like a freight train and sounded like one too.
 

thanks to Audi for picking up the bill for new pads and rotors all around :-)
