Scored discs

[SimonR]

Quick update, after a comment I left on the facingbooks, Audi asked me to PM them, I'm awaiting a call back. I expect they'll give me a free R8 or something as an apology

Folks,

out of interest what life are you seeing out of the rear pads/discs compared to the front (car has done 27k of mostly motorway)? Being told mine need replacing after taking the car in for brake judder. I pretty convinced the issue is from the front given these were replace 2.5k ago and seems a sweet spot in terms of life to play up.

cheers

Rears seems to have a bit of a issue with pad deposits. Before getting them replaced, it's probably worth a visit to a pro cut disk skimmer to see if they're salvageable.

Does anyone know what thickness the discs need to be at for Audi to say they need replacing? I'm 700 miles into my bed discs and I have a good old lip starting already! Be interesting to know how much I have lost and how much is left.

Is the outer set of dimples not the indicator? When they are worn flat discs need replacing.

[SimonR]

Mine were not worn flat, I was told they needed replacing anyway.

In fact I have just checked the Audi cam again, they are not even close to flat. Is there an Audi tech on here that can confirm worn dimples are the indicator of a worn out disc?

The B7 discs state their minimum thickness ie disc is 34mm when new and needs replacing at 32mm. Don't the C7 discs have a similar min thickness written on them?
