You need Bolts from the S2, the S4 V8 Bolts don´t fit.

I´m already waiting to make the upgrade...
I haven´t money but it isn´t too expensive, not?

Arround 500 pounds, not?

[Lars Erik Johannesse]

now i`ve bought following parts;

carrier ;
8E0 615 425

Calipter ;
8E0 615 423 /424

disc ;
8E0 615 601 R

But its something wrong here, the caliper will not fit on the carrier, its about 2cm missing to the bolts.

i have read somewhere i can use the brakedisc Ø300x22 without reduce them to Ø280 on avant/sedan.

Someone can give me correct part number for caliper to use on the carrier ? i can post picture if someone not understand what i`m meaning.

[twoqu]

Double check your parts against the list in the post above yours. The letter is very important!
For example 8E0 615 425 is a brake carrier for 245X10mm disc!
Perhaps a pic would help as I am not sure where the problem lies. Do you mean the calipers will not bolt up to the bracket or that the bracket won't bolt up to the hub carrier.
Either way sounds like incorrect carriers or calipers.

[Lars Erik Johannesse]

You will see the bolt hole here will not fit.

it must be the caliper.


so, someone have a part number for the correct caliper from a audi s4 4.2 B7 ? my family album not going so long.....
or maybe a webshop i can order these parts

[twoqu]

Hmm..
It looks like you have ordered regular A4 rear calipers (8E0 615 423/4) suitable for 245X10mm discs and not the correct S4 ones. The horizontal ribs are a big clue! As I said previously, it is important to get the letter at the end correct!
The part numbers are listed on the thread and above and very depending on the colour required.

[Lars Erik Johannesse]

its looks like i have ordred wrong calipers without the letters.

So the correct part number i need is following ;

8E0615423C
8E0615424C

And this is from a Audi S4 4.2 V8 B7 2006 age?!?!?!

[twoqu]

For the silver ones, yes!
A small difference in letter means a big difference in part! There is going to be a big difference in price as well unfortunately!
In the Forum's defence, all the information needed was in both the threads you have posted in.

[AndersS2]

You need Bolts from the S2, the S4 V8 Bolts don´t fit.

these s2 bolts are also not long enough. All OEM bolts my local Audi dealer could supply me with, were fact too short for bolting the carrier to the s2 hub.

I had to cut mine in custom length after finding the right size in acceptable enough strength (12.2)..

[Lars Erik Johannesse]

witch bolts i need to use on the carrier on my avant?

[AndersS2]

the bolts im talking about is those four (4, 2 on each side), which bolts the carrier to the hub.

Just try it out for yourself, then youll se that none of the oem bolts are long enough.

[Skull]

are the parts from an s4 year 2004 any use for the rear brake upgrade?

[Big Lee M]

are the parts from an s4 year 2004 any use for the rear brake upgrade?

Yeah that's what I have on mine. B6/B7 S4 V8 rear brakes are what you want.
