View Full Version : Attention to anyone that upgraded to S4 rotors with A4 calipers and S4 carrier
The S4 rotor on my friends car is barely clearing the caliper. The pad sits correctly on the disc so I suspect it isnt a carrier problem.
So I think this means the B7 caliper is not the same as B6/7 S4s. [headbang]

you need s4 carriers to do it right(calipers are the same). Any dearlership will have them. ECS has them but I dont think they sell them seperately.

That was with S4 carriers. Some A4 calipers have a tighter braces that wrap more tightly around the 320mm rotors. When you move them out to 345mm rotors with the S4 carriers, they drag lightly on the outside of the rotors.
Without S4 carriers, there would be no way to assemble as pictured.

Well worth the upgrade to the 6 piston, thats the only upgrade I could not bring myself to sell lol.

The caliper is looking pretty thin there already. Dremel really?

Are you using the OEM carrier or the ECS carrier?

Is doesn't take much. Also, when you are torquing the bolts, wedge a screwdriver between the rotor and caliper to use any slack in the connection to your advantage.

you need s4 carriers + rotors and can use a4 caliper.

Mine did the same thing... a little bit of Dremmel action like audimeister said, and it went away after a couple of days of "spirited" braking.
Yeah, BBK is always on my mind... but for now I guess good pads & fresh fluid will help me extract the most of my OEM setup. I'll know for sure this summer: pretty busy lapping season ahead!![drive]
Anyone experienced these?:

Will do when I get my car back. It's been at the dealer for a week and a half for its last visit before the warranty expires...
Slightly off topic, but is the upgrade to the S4 rotors and carriers noticeable, is it worth it?
I have been thinking about doing this, but I wanted to manage my expectations.

Bringing back from the dead, but still a lot of confusion with these carrier.
It seem's 06 (maybe before 5/29/06 as ECS mention) http://www.ecstuning.com/Audi-B7_S4--V8/Braking/Caliper/Front/ES437454/
have the B6 caliper, which are a bit smaller. Then we might have better luck with the B6 S4 caliper carrier?http://www.ecstuning.com/Audi-B6_S4--V8/Braking/Caliper/ES6503/
To those who did that upgrade, can you post your caliper Part #, car year and if you had any clearance issue?
thx

You are correct in 06 it was a split year between carriers i believe most go with the b7 carriers
Mister W
08-17-2012, 10:09 AM
And some of them have clearance issues. As soon as my GF stop taking my car, i'll check my caliper part number and compare with B6 or B7 caliper.
For now those are the carrier part number i found.
8E0615125C OEM for B7 S4 (after production date of 5/29/06)
1K0615125B OEM for B6 S4
1K0615125BX Schwaben from B7 oem big brake upgrade
So if you guys know what carriers you installed, what year is your car and if you had clearance issues, please share so we get straight with that upgrade.

I used the ecs upgrade kit to get to s4 brakes all around and up front i had clearance issues. Several threads talking about it. IT took 15 minutes and a grinder to fix the problem. Pain in the ass but worth it once its fixed.

08-17-2012, 12:15 PM
I think the main question is who has used oem brackets with no problems and what year brackets were they were they a b6 or b7 bracket. so before the split in 06 or after the split in 06.

Cant wait. I'm waiting for your review before ordering.
But i see that you have a 2008, and might not have the same caliper as me (2006). With the 2007 +, i believe the other part number fits. Since 1k0615125b is for 347mm disc, you should have no problem.
Your review with part number will surely help the DIY for this mod. If you can see your caliper part number, let us know as well.

I'm dealing with the fitment issues now. I received the carriers with ECS's kit and they caused the caliper to rub against the rotors. ECS thought I had received the wrong carriers so they sent out carriers 1K0615125BX (for 347mm rotors). These were the exact same as what originally came with the kit and didn't fit either.
Grinding the caliper down worked to get the rotors not to rub while moving, but under braking they still rub. I'm sure I could grind out more of the caliper, but it's so thin already that both myself and my shop were not comfortable taking any more off.
ECS's customer service has been great with getting me the parts and now in the refund throughout all of this. They said that they are going to look in to it further and do some test fitting with my parts when they get them back.

08-28-2012, 06:06 AM
Did you order the Schnabel or oem carriers?
Why not find a local machine shop, and have them machine some of the disc off to reduce the diameter? It can't be too much to have that done.
Existentialist
08-28-2012, 07:13 AM
Did you order the Schnabel or oem carriers?
They were Schwaben carriers. I'm confident there are identical to OEM and it's the calipers causing the fitment issue. There are other threads about this topic out there where people tried OEM and the Schwaben carriers and had the same result.
Why not find a local machine shop, and have them machine some of the disc off to reduce the diameter? It can't be too much to have that done.
The plain rotor kit came with rotors that were balanced by removing material from an area on the edge of the rotor. You risk taking the rotors out of balance but this could be another option.

Mister W
09-25-2012, 01:54 PM
I'm still searching on Etka an on the Web. I wonder if it could be related to the brake PR number. I have 1LA , some have 1LJ. With my model on Etka, it says that i have caliper # 4F0615123 (cant search with my VIN, it wont allow me).
In the 2006 S4, they split the year in two with the VIN numbers.
I've search on Jim Ellis with my caliper number and brake PR and found another carrier number that they say fits a 2006 S4 and A4 Avant. But i'm not sure if it really fits 345-347mm disc. If someone have better knowledge of this, it could help. that new carrier # is 4F0615125.

Well, i finally got time to install front brake disc and carriers.
I ordered these from ecs 1K0615125BX Schwaben , since i have an early 2006 avant. i have stoptech disc. I didnt find a part number on my calipers, but you can see a number on one pic.
So the verdict is that it rub [=(]. I can turn the disc by hand, it rub so barely that it almost dont remove the paint from the disc. I guess i wont have to dremel, it will do by itself.

x2. OEM carrier have NO problems. Schwaben will most likely always need modification to fit
Mister W
11-15-2012, 09:50 AM
IMO, the problem is not the carrier. After many research, some people have problem with the schwaben and they tried OEM after and get the same issue. The schwaben is a B6 S4 carrier, the other part number is a B7 S4 carrier. Audi split 2006 in two, so part of us seem to have a different caliper (the B7 one) that wrap closer on the disc. Early 2006 still had some B6 caliper. Not confirmed by audi, just what i concluded.
On the first page you see people with problems and some that have clearance. Maybe it's the disc manufacturer that make them 1-2 mm different than other,maybe it's the hub mounting points that are different, i cant say. But show me the oem versus the schwaben to prove me they are different , and that schwaben issue will be close, but i doubt ECS didn't already checked that.
But for what that i conclude, i have more chance that the schwaben fits on my car that the B7 ones. Plus, it's hard and costly to me to ship them back since i'm in canada, and paying 90$ for the schwaben instead of the doublefor the oem make's the try easier.
By keeping this thread alive, i was hoping for people that have done this mod to participate and give the carrier part number they have , the car year and other infos, if they rub or not with pictures.
There is some responses, but it lack infos.
I would have wish that this mod was clear once in for all, because searching for answers brought me no where .
I'll love to try the oem one, but too costly. I'm already stuck with B8 S4 carriers that was a buying mistake and trying to sell them.

That could be the problem. 345 mm of brake pad surface vs 345 mm disc diameter is different. I'll mesure mine tomorrow.
One thing too, it seem that my stoptech disc are not perfectly centered. When i turn then, they scrape on one side only. I loosed the small screw and i could feel there is an half to 1 mm play. But it's hard to center them.
For sure, i did felt a difference in braking, but the most difference is in rotation weight. i can feel it when i'm slaloming on the road.

I'm in the middle of this now - rotors and calipers rubbing badly and its not driveable - took to the shop b/c I thought I had messed something up. I'll get the part numbers tomorrow if I can find them all my details are:
Car: Split year 2005.5 B7 A4 Avant 2.0T Quattro MT (Production date = 12/26/2004)
Caliper Carriers: Schwaben carriers (gold ones from ECS) = Part # 1K0615125BX
Calipers: OEM 2005.5 A4 calipers.....sorry could find part number (production date = 12/26/04 which may be why my calipers are too shallow and not a direct swap with S4 rotors)
Rotors: Adams S4 front rotors (345x30mm)
Pads: EBC Redstuff B7 S4 fitment part # DP31495C
Dust Shields: Audi OEM B7 S4 dust shields (I know I didn't need to but I wanted to do it right)

Had a shop grind down the calipers on mine and as of 24 hrs later they work. I'll update if things change - the consensus I have come to as well as a few others is that early year B7's such as those which are the 2005.5 split year and some from early 2006 (possibly before 6/04) may have a shallower caliper. Some guys have stated the early 2005/2006 B7 may have used B6 calipers which Audi will not confirm - just a theory.
