    Let us know how it turns out and what color you decide to go with.

    Hey guys, do we need the brake sensor from the a6/a7/a8 to fit this onto a b8 a4/a5? Can we just re-use our existing brake sensors on the new calipers?

    380mm A8 Brake Upgrade for A6/A7

    And powdercoat is done.

    This is the G2 epoxy next to the super durable wet red powdercoat




    Here are fresh oven pics





    Next to rotor

    Now I'm just wait for my "quattro" stickers in silver. Was close to doing audi sport or S-line, but I have the quattro script in my front grill and rear window so consistently is my friend.

    Look great! Nice work going the extra step in powder coating.

    I have to say, the upgrade to the 380mm rotor has been Awesome!

    After the bed in period there is a noticible increase in stopping power at any speed. I can further attest to this as I used the same pad compound both before and with current setup.

    One other area where I notice the difference is when using ACC. The car slow noticibly faster when using. This caught me off guard because someone at one point said the rear brakes are used for ACC. Not true.

    Not that the old system is bad by any means, but these are awesome. You can never have too much stopping power and the price is right!

    Cool glad to hear you are happy with them.

    Which pads. I am going akebono euro ceramic for the low dust.

    As got the powdercoat, I kept doing stuff for others and never took the time to do mine right. So I did them. The powdercoat is fun to do. I gave debated selling the tools but that's not worth it. Every now and then I do stuff for my self and friends.


    I used the ceramic paint for the disks. Maybe it'll help prevent rust maybe it won't they are $36 rotors if they suck then I'll have to pony up for the the real ones.

    Hey, do you guys know if the a6 rear calipers will directly bolt onto an s4? At first I thought they were the exact same calipers as they both utilized the 330mm rotors but its been brought to my attention that the thickness is different. Which means the caliper is also different? Sorry for the OT guys

    You're asking questions we don't have the answers to. This thread is pertaining to the C7 platform.

    Do what we did, pony up and see if it works.

    The rear rotors interchange part numbers between B8-S4 and C7 w/330mm x22mm. They both have 68mm hub bores. And depth of 36.2.



    The brembo rotors I have were bought for an S4,but they look identical and measurements are the same.

    You will need to figure out what you need for your car.

    OK great, thanks for that diagram. That looks to be a good starting point. I'll dig through other part numbers to see if calipers are interchangeables. Thank you sir!

    Great feedback, glad it worked out. I was afraid the size wouldn't matter...lol. I want to go lightweight rotor, but I may just use the same rotors you got for now.

    For the price you can't beat them. They actually only weigh ~2lbs more per corner.

    I was this close to ordering the two piece rotors tonight, but beyond looking wicked cool and the 6lbs saved per corner you won't feel it or see it on the drag strip. Maybe good for a hundredth or two.

    I was thinking about running light weight rotors also but for the price, I don't think it was worth it for the results. It seems lightweight rotor weight savings is too close to the hub to really produce as much improvement as say lightweight wheels

    380mm A8 Brake Upgrade for A6/A7

    I installed the setup, have to say I was impressed by the initial pedal feel and responsive braking.

    Genuine Audi pads on both sets. I was gonna swap to akebono, but could not get a set this weekend. I also like that I could compare the larger rotor/pads back to back.


    1. Firmer pedal. Could be from flushing old fluid out, but also larger pads and rotors.

    2. Scrubs speed well, smooth and easy. Again this is obviously due the increased diameter.

    3. Fade resistance- I didnít drive hard enough to induce brake fade but this is a factory system designed for the A8. It is not a brembo track setup, I feel I could start to melt the pads if really pushed.

    I have very pleased with the result, under $500 all in and it is a great feeling setup.

    Room for improvement.
    More aggressive pads
    S/S lines
    Lightweight Rotors.

    I didnít really feel the factory 356mm were under performing, but this setup feels very good.

    FYI they are 42mm pistons,I measured the factory setup at the dust boot and got 41.4 I didnít disassemble them fully but I assume they are 42mm as well.





    Iím not sorry I took pictures of the car dirty. You guys can deal with it. Iíll wash it later.

    Amazing little upgrade for under $350, hard to beat! Your powder coat came out very nice!

    With the extra money saved vs the S6 caliper upgrade I took the plunge and ordered S6 caliper carriers for the rear. Once they arrive from Germany (~two weeks) Ill report back how they mix into the equation.

    As much as I want LW rotors for the front, I think I'm pretty sold on the Wearever rotors for $1000 less. Looking good guys.

    Yeah, it's hard to ignore the numbers.

    I was set on painting my calipers silver, but now thinking dark blue. Am I crazy, or would this go well with a black car?

    Does the A8 caliper share the same brake pads as the a7 caliper or are they different? I've been looking for brake pads and there seems to be so few options. Most sites only sell the fronts strangely?

    Looking for Hawk hps 5.0 pads but it seems they only make that for the front. Does anybody know why this is?

    No, the pads are different I posted some centric diagrams earlier in this thread.

    The A8/SQ5 uses a larger pad, about 1cm wider on the long axis.
    This is the inside radius of the brake rotor.

    It is also why these brakes are ore effective, larger rotor and pads.

    Yup. Rear calipers are the same on the A6 and S6, sans the carrier and painted caliper.

    Rear brake upgrade complete

    Heres what you need to make it happen.

    Parts needed

    Rear C7 S6 caliper carriers, PN
    -4G0615425A
    -4G0615426A

    Rear C7 S6 rotors

    Tools required
    -1/2 ratchet wrench
    -18mm socket
    -13mm and 15mm box wrench
    -Torx 30 bit

    The process is exactly the same as changing the stock brake system, except after you've removed the carrier you'll undo the brake dust shield (Torx 30 bit) and now install the S6 rotors, carrier, and done.







    Taking my time and cleaning it was about an hour job.

    FYI, the carriers are black, but I painted them silver prior to installation.

    Once they are bedded I'll be excited to see the true braking potential.

    I have b8 S4 and bought c7 a6/a7 calipers and was told they would fit 356 'll rotors. According to this, i could fit 380mm a8 rotors? Can someone please confirm?

    I thought the calipers btwn the a6/a7 were the same as the a8, only the carriers being the difference.

    It was pointed out to me that both the caliper and carriers of an a8 are different so in order to run the 380mm, youd need to get the new caliper and carrier.

    Update: swapped to akebono pads, did rear brembo rotors and akebono pads.
    Snow tires mounted, added the quattro script. Very clean set up.

    Another rotor option now available at advance auto parts

    https://shop.advanceautoparts.com/p/...462%7CL3*15696


    FYI oem rotors have dropped to $250ea. So eventually Iíll swap over to quality rotors. I have a slight shake when brake lightly, then smooth if I use more force.

    I will tear apart the caliper again and look for a sticking piston. Very minor issue.
