front o/s break disc

[jpda4]

finally got round to taking a photo...
noticed 'marked' front disc the other week when washing car, at the time thought it was down to washing and would clean up once driven...anyway they are not cleaning up!
It looks shocking!! pitted and scored
The car stops as it always did and dips the nose when breaks applied, rears disc shinny and clean...

what going/gone on here? could the outer pad be stuck? the disc gets warm to touch
dont remember the 'normal' noise when a stone gets stuck between the caliper and disc, so no idea how the score has happened

know it not going to be worth going for a warenty claim, wear and tear will be the reply

It does look like a stone that has scored the disc. The pitting and rust is down to the salt that's being put on the road at the moment. When they stop putting that down the discs will clear up properly

thanks
nothing to worry about then, until audi get it for a service and advise to get them changed due to the scoring
