    Hi Guys

    been searching the forum for a clear answer on brakes and upgrading them but i cant seem to find the certain answer to my question.

    i want to upgrade my brakes on my 2003 Audi A4 2.5TDi Quattro as i feel i just get too much brake fade and the car is too big for the brakes it has on.
    i am running genuien Audi RS6 18inch Alloys with 10mm spacers on the front, i want a straight forward bolt on upgrade no messing about i want the calipers to bolt on and to slip the discs on bleed and hey presto ( never that easy) but doable in half a day?

    i have been looking through ebay and this site and as far as i can see i have a few options

    S4 Calipers pre facelift 320mms discs or Facelift 345 discs ( if they would fit ) Braided lines and performance pads

    Audi A8 Calipers and 320mm discs

    Seat leon brembos ( not sure if they will directly fit )

    please let me know your thoughts ect and your ideas

    Realy? hmm i dont know i am fairly heavy footed. thanks for the fast response.


    i did fancy the b5 S4 upgrade BUT the B6 S4 upgrade use 345mm discs which might fill the wheels better?

    Any more ideas or recomendations

    agree with tdi sport about the standard factory fit brakes, however if you do want to upgrade then B6/B7 S4 or B7 RS4 would be the logical choice......

    I've never found my 2.5q brakes lacking in anyway, I regularly commute in the middle of the night so can put them to the limit when opportunity presents. I'm inclined to agree something must be amiss with yours if they're that bad.

    B7 2.0T brakes are a popular mod too, I'm not sure on sizes as I've never really felt the need to look into it.

    2.5 brakes are 312 vs 288 for the 1.9, although I think 1.9q's might be 312 too but I'm not sure on that.

    White Akita, what settings on VCDS to do that, its a new one on me....!

    i recently replaced the discs and pads. I went for brembo max discs, these are grooved but not heavily, and a set of brembo pads,the improvement was amazing, nearly shot through the windscreen the first time i stamped on them. Also had a full fluid change, £30 at my local independant. Discs and pads cost £130. very happy

    I have been wrong before! That was my understanding, but Audi are never scared to throw a curved ball when it comes to spec levels!

    True.. Audi do seem to enjoy putting different variants of everything on different models
    The alternator clutch bearing went.. The dealer said it could be one of many and i had to get the model number off the clutch!
    Cheaper than a new alternator though ;-)

    Mine is a 53 plate Sport.... Not sure if this throws things even wider on what it will have standard :shrug:

    I have just changed up from an 2.5tdi A4 Cab to an S4 cab, and the brakes are night and day. The S4 brakes feel so much stronger and confidence inspiring.

    So I would say its a worthwhile upgrade..

    I'm guessing the 2.5 cab being a 163 had 288 discs though?

    What I have seen is that most model's have the 288mm brakes, but the 3.0 petrol is the one that had the 312mm brakes.

    We've discussed this before, and I 'think' its the quattro models that have the 312mm brakes.

    Mines the Sport the same as yours. I wonder if this has uprated disks to the bigger 312's as it does have uprated/lowered springs/shocks

    A few year ago i had a 2002 b6 1.9tdi awx 130bhp remapped and after he mapped it he told me to go for a bit of a drive to see if i was happy with the improved power, which i was very happy but i also noticed my brakes were not as sharp as they were before the remap even at slow speeds. I told the tuner this and he told me that there were a few settings for the brakes, he then plugged his laptop back in and within 10 mins my brakes were back to razor sharp. They were definately adjusted electronically.

    I have a full brake setup from a B7 2.0T that I'm looking to sell but need a idea what they are worth if anyone knows.

    I paid £250 for a full S4 setup with hubs and driveshafts.

    I've put 2 links to S4 setups off the B5 in the ebay section going for low monies.

    OK cool, just looked at them and also found just caliper for a B7 2.0T at £280 so a full front and rear setup for £350 should be a bargain.

    OEM Brake Upgrades

    B6A4 1.8t-
    Same Caliper as B6A4 3.0
    Front Rotor: 288x25
    Rear Rotor: 245x10 or 255x12

    To check size of rear rotor, remove and check part #:
    8E0 615 601 P = 245x10mm
    8E0 615 601 D = 255x12mm


    B6A4 3.0- Same Caliper as B6A4 1.8t
    Front Rotor: 312x25
    Rear Rotor: 255x12

    B5S4
    Front Rotor: 321x30
    Rear Rotor: 256x22

    B6S4- Same Caliper as B7A4 & B7S4
    Front Rotor: 345x30
    Rear Rotor: 300x22

    B7A4- Same Caliper as B6S4 & B7S4
    Front Rotor: 320x30
    Rear Rotor: 288x12

    B7S4- Same Caliper as B6S4 & B7A4
    Front Rotor: 345x30
    Rear Rotor: 300x20
