Sorry - but I have one more question. Because the booth sides are now not available on stock - the dealer ask me to send me 2 pcs of 8K0615126 - and he say that this will be work on both sides. I'm not so sure because in this Audi documentation is exactly 8K0615125A left and 8K0615126 right. Know maybe somebody if in fact is possible using the 8K0615126 for booth sides (left and right) ?

I'm not sure but I think they are different
To model the disc 345x29, 5 mm is used 8K0 615 125A (left) and 8K0 615 126 (right)
To model 345x30mm used 8K0 615 125A (left and right)

Hi Spijun,
Sorry to resurrect and old thread but hoping you can help.
Are you able to tell me the correct rotor sizes (F/R) for the 2010 Q5 3.0TDI?
I'm in the process of changing out the brakes and I need to do the rotors at the same time as they are under size. Most sites that list Q5 brakes list the front as 320mm but my measurement of the original rotor comes to about 345mm (+0/-1). I haven't bothered measuring the rears yet but I'd guess they would also be the larger 330mm ventilated rotors.
If you'd be able to confirm for me, it would save me some hassles.

Here is a link to one: http://www.jimellisaudiparts.com/sho...category=21741
They typically sell at list. Places like AudiUSAParts.com or some other dealer connected sites often discount.
No guarantees w/ out a prior install confirmation, but yes it probably is just a bracket difference from a glance at the parts diagram. Pretty common Audi practice to use the same caliper across a lot of Audi applications, and then vary the bracket and rotor and (sometimes) pads to do different sizes. Same on my A8 for example as between the W12 + S8 with bigger rotors, and then the 4.2 with the base U.S. size.

When looking at various sites to find the caliper bracket to support 345mm rotors on my wife's 2011 2.0T, I found the following: Link
This is the lowest price I've found for the caliper brackets, but I'm concerned they might not be the correct ones. Any advice from the AW community would be appreciated.

spijun,
Adding to the mystery, their site is not able to find either 8K0615125A or 8K0615126. Even stranger, you can find the 4G0615125A on the ECS website listed as an Audi/VW part.
