    OEM brake upgrade for 3.0T?

    Guest-only advertisement. Register or Log In now!
    Hello,

    I just bought a 2009 A6 3.0T Avant.

    I am going to tune this car soon, but I am feeling that the OEM front brakes doesn't really cut it and I don't think a swap of pads will be enough. Recently did the Q5 Brembo swap on my A4 B7 and it has amazing brakes now, so I'm looking for something similar. The problem seems to be that there isn't a lot of people doing brake upgrades to their A6's(at least compared to the A4 community), so I can't find any writeups about it. Maybe I am not searching good enough. I have found out some stuff, but I need assistance to find out what fits or not. Can anyone help?

    1. I read that A8 brakes should work on the A6 4F/C6 straight bolt on. Is this true or will it affect ET? There is an A8 setup that has 360mm discs and 2-pot floating calipers. This is a very cheap upgrade, the calipers can be bought for about $100 each new.

    2. Some combination of RS4/RS6 calipoers/discs seem also to be bolt on? But Im unsure what part numbers. Does anyone know? A german ebay seller has been offering a kit like this for the A6 for a long time:
    http://www.ebay.de/itm/Audi-RS6-Brem...tf-rzkk7kpwsIA

    I know that there is StopTech and Brembo GT kits for this car, but they are like $4000. If I source OEM parts on the junkyard, I can find a pair of RS6 calipers for $5-600.

    any input on bigger front brakes for this car is appreciated. I would prefferebly not want to use discs larger than 365.

    There is a Porsche brake upgrade that the pre facelift cars were doing, don't know if it works on the C6.5, 2009-2011. I think they were off of the Cayenne. 17Z or something like that? It's been a while since I looked.

    No one at the dealer knows? I'm sure a tuner would know.

    I heard that route does require a custom bracket to be made though

    Too big--- that requires at least 20" rims, no? I need to use winter tires on this car and they are insanely expensive in anything larger than 18".

    Why do you feel thereís a need for replacing your brakes? The 3.0 come standard with 347 mm front desk and 330 mm in the rear. What type of driving are you planning on doing that would require changing your brakes?
    Unless youíre taking your car to the track on a regular basis or participating in an autocross, changing out your brakes for something different it is overkill in my opinion! That is unless you want to have bigger brakes for looks! Upgrading your current set up with a different rotors from ECS or Adamís rotors and adding Akebono euro ceramic pads and stainless steel brake lines will resolve all of your concerns regarding the brakes being underpowered for the car.

    Let's take that mindset and reverse it somewhat: Why does the RS6 have 8-pot brembo calipers in front? It hardly weights any more than my 3.0T. I'm quite sure that the 347mm 1-pot brakes would stop the RS6 too, maybe with even smaller discs, say 321mm.

    I have an aggresive driving style and I want brakes that I can depend on even when the speed is twice the legal limit! I know a caliper with more pots will give me what I am looking for, and if I can do an OEM upgrade it will be cheap too.

    put a decent pad on this car, and you would be surprised at how well it stops. I have an aggressive driving style myself, and not once have I ever thought about upgrading to a big brake kit when street driving. Now if you are talking track, that is a whole different story.

    Yeah but say you could spend another extra $400 to make the brakes even more effective. Would you do it?

    EDIT: From what I understand it could be possible to use A8 brakes in front. The discs needs to be replaced also soon. So the extra cost over the 347mm oem setup would be the larger 360 discs, but they can be found at about the same price. The pads are also the same price. A set of brand new 2-pot A8 calipers is about $220. The OEM brake lines will propably work but I would change these into a setup of steelbraded ones, so maybe another $100.

    So $320 extra to make the brakes more effective than just a pad swap. Even if they don't get much better, $320 is not alot of money.

    I would buy a slotted set of stock size rotors, and a good set of brake pads. Maybe also do stainless brake lines, little better peddle feel on the street and track. If you plan to track it, then upgraded brake fluid as well.

    Hello,

    after much searching around I have now found out 2 things:

    1. There is an OEM Audi brake option which is called 1LL, which is only fitted to armoured A6's but is standard on many Audi A8 and VW Phaeton. This is bolt on 360x34mm discs with 2-pot calipers.

    2. When I searched around I realized that both the calipers and the carries on the A6 are the same as on the S4 B6/B7. The only thing that differs is the discs which are 347x30mm instead of the S4's 345x30mm. That leads me to think that the Q5 calipers can be used on the A6 C6/4F also. I recently just did that mod on my A4 B7 so maybe I could just swap the calipers and pads from it.

    EDIT: If you are not familiar with the Q5 brake mod; it's 4-pot fixed brembo calipers made in alu.

    we will see what happens.

    few bolt-on options from my top list:

    1) Audi Q5 Brembo 4-pot calipers
    347mm OEM Audi A6 C6 rotors

    2) Brembo BM5/17Z
    Mercedes A 230 421 08 12 (Ate 24.0132-0153.1) 330x32 rotors

    3) Brembo 18Z
    rotors:
    Mercedes A 221 421 16 12 07
    Mercedes A 221 421 11 12
    Mercedes A 221 421 16 12

    you only need to enlarge the center bore of Mercedes rotors from 67 to 68mm

    if you need some help with part numbers etc.. PM me;)

    I'm gonna go with this option since I have the calipers already, I checked the brake lines and compared with the A4 B7 ones. The difference is only 5mm so maybe the custom steel braided lines I had made for the A4 will fit the A6 too.

    Pairing this with Redstuff pads and Zimmerman sport rotors(drilled) all around. I will get back with pictures and result.

    BTW: is it necessary to put the electric parking brake in service mode?
