From my own experience I find the standard brakes inadequate for anything apart from taking granny to the shops. The S8 in particular is more capable than the OEM brake installation would suggest. If fitting upgraded pads reduces stopping distance a bit; upgraded disks a bit more. Bigger disks more still; vented disks better still. Grooved disks more, grooved and drilled more + 1 and so on. I have been tracking my S8 since I bought my first one as it's such a capable car. A mile muncher that is very comfortable. But when you want to stand on the loud peddle, you will want to know you can stop even quicker.
Remember, the manufacture, generally, fit the least efficient brakes they can to meet the required standard.
My 2 penny worth.

The Febi discs and TRW pads were installed today. Immediately they feel better as they now bite without me having me having to stamp on the pedal before rear ending the car in front that has stopped for a red light

They also do no squeal like a pig anymore which was so embarrassing.

My mechanic noticed that the old discs were heavily rusted front and rear and had what appeared uneven wear. He thinks they were just a cheap pair the previous owner slapped on.

I’m much happier and it’s another job ticked off the list. Thanks for input as usual guys. So far, very happy with them

I've never been entirely happy with the Pagid pads I fitted a year or 2 back so thought I'd order a set of the GDB1523 Mikki recommended.

I can confirm they fit and much easier than all the filing I had to do on the last set and they already feel much better.,

Out of interest I dug out the Pagid part number I used last time (selected via ECPs reg checker)

and they were 101441238

These tracked back to the same part number Autodoc recommend which is TRW GDB1506

https://www.autodoc.co.uk/car-parts/...51q?search=OEN 4D0698151Q&supplier%5B0%5D=833

When I look up GDB1523 Autodoc say they won't fit my car. Which of course they do.

Anyone know whats going on here or is it just a case of their parts cross reference being flat out wrong?

Sorry to add more to this.
I have been searching autodoc.
Anyone with Pt numbers? I can see there are some differences...

Many thanks.

You don't mention exactly what D2 you have, so I'm assuming it's a FL D2 S8 since you've posted in this particular thread. With that in mind, part numbers are as follows:

Front
Disk - 4D0615301B 345x30mm B- Brembo
Pads - 4D0698151L - pair

Rear
Disk - 8E0615301B 280x22mm - PR Code 1KW (this is the bigger of the two disk sizes)
Pad - 1J0698451H - pair

It would help a lot going forward to add your car specs to your signature line, in case the above information doesn't apply.

Thankfully Brian has answered the refurb question, as I have no idea.

Car details - Add them to your signature (User CP > Edit Signature). That way, it's always visible on every post you make, and no one has to search for it. It makes things easier.

That's what annoys me about the Facebook groups (A8/S8 related), where they ask a question about their A8/S8, and forget that there are 4 generations of them with a multitude of variances.
