I think what they are describing is a ghosting effect you can get when the cutting tool goes over the hole. This tends to happen with an intermittent cut.Thundercliffe81 wrote:Ok.
So, the saga continues. Went to Redline and the good chaps there said they don't skim these brakes anymore.
Reason being, because they drilled on both sides, when they skim one side, it's leaving an impression (or something like it) on the opposite side. This 'impression' creates a drone-like sound and effectively creates just another issue.
Now, I've not read anyone on here, and with the B7 too, having this issue. So, I have another place that might do it for me. But Redline say they just replace the discs and pads on this car now. They did say it was a weird problem but explained it pretty well.
They also said it sounds like the rears as I'm getting vibration through pedal and wheel.
Looks like I'm booking into Audi. They said I should go back to Newcastle where I got it but that's a very long way away for a maybe. Think I'll book into one closer and attempt to get a truth diagnosis out of Audi. Yeah right...
This is becoming tedious but I did say when I got the car that I wanted to learn more about how things worked and not get fleeced.
Cheers guys.

It will look like a repeat of the hole size.
The discs can be re-cut on a lathe ensuring they are running true to the mounting face and both sides cut in the same set up.
Have you measured the disc thickness, as all this talk of re-cutting is academic if they are close to the wear limit! Personally if your car has done over 40k miles I would just bite the bullet and replace them.
