Does the bedding in procedure help with this? It is not warped discs that the majority of us are suffering from. It is caused by light braking and that can happen at any point during the life of the disc, can't it?
The key is to avoid regular light braking regardless of disc age / mileage.
Unfortunately, for some of us that live in the sticks we only need light use of the brakes as there is no traffic. I had no troubles with this until I moved out of London; driving fast in London involves lots of heavy braking; keeps those discs sweeet!
So for those sufferenig with this, changes your discs and move to a denser populated area and drive faster.

Cheers Brooner, I'll give this one a try as it says it can possibly cure judder At the very least it'll give me a chance to go for a nice drive. If it doesn't bloody snow that is.

How many miles have you done in the B7? Why did you need to replace the discs?

[Brooner]

got 45k on th B7 change at around 40 ish advised on service

Just been out and followed the zeckhausen document. Couldn't do it as good as I would've liked as the road was a bit busier than I'd hoped but after an extended cooling off drive at 70mph the drive back into town revealed the judder is virtually gone. Happy bunny!

Good stuff!!! Maybe I'll have to give it a go as well then.

I am new to this Forum as I have only just purchased my 07 RS4 Avant last week, knowing it had serious brake issues.
Not judder, just no brakes, and with pitted discs with high lips on the front.
It was a very low mileage example, but had been standing around too long without regular usage, the brakes were crap despite recent full Audi Service!
Through this forum, I got onto Marcus at Disc Skimmers, who probably is the only guy in the UK that can sort out brake judder and brake issues on the semi floaters of an RS4.
He arrived in his mobile unit and first checked that the discs were within thickness limits, carefully dissembled the calipers and tied them out of the way, finding that the pads were down to the rivets and corroded onto the retaining pins, so not moving as the should.
He then set about skimming and truing each disc on the car with a Pro Cut Lathe, that he had modified himself to deal with RS4 semi-floaters, until they each ran with zero "run out".
He then fitted new EBC, Yellow Stuff pads, supplied by me, taking care that they would freely move on the pins and sliders, using "copperslip" sparingly.
This involved removing some of the yellow pad paint before he was happy.
He took his time and was very thorough and the whole process took 5 hours.
For this excellent and very professional service, he charged me £320.00 (NO VAT)
In talking to him it turned out that he was a motorsport engineer with Formula 1 experience, now working on his own.
He had come across many brake judder issues with RS4's but seemed to have all the answers, particularly with bedding in pads discs and and brake usage.
The other main cause for judder was refurbished wheels that had been painted on the mounting surface, which should be dead flat and true.
Paint and in particular powder coating on the mounting surface of the wheels can affect the wheel and the disc running true and cause judder in a very short time!
The result of his work is that I now have RS4 brakes that work better that the Brembos on my 996 GT3, smooth, but powerful and progressive as brakes should be.
If your brake judder persists I would suggest you contact Marcus, who may be able to solve your problem at very little cost!
His mobile number is 07824 903006 and his website can be found at http://www.discskimmers.com.
I would recommend this guy to anyone with RS brake issues!
I hope that helps - By the way I love the RS4, particularly now I can stop it!

Phoned this guy today to get some information for my local place, he was extremely helpful even when he knew I was to give him no business.

Had the rear discs skimmed on car today, total £57. No more brake judder.

Note to self "do not park with handbrake on for 5 weeks".

^ my brake judder has completely gone. I replaced my rear discs and pads.

[floydstar]

Hi madmonkee - What was the width of the discs once skimmed and do you know what is deemed 'safe' width? i.e. how much could you take them down to?
