Hi,

Would anyone know if these (8R0615106BN / 8R0615105BN) Q5 brake calipers would fit on the audi a5 b8.5 3.0tdi brake carrier/discs, apparently they fit 320mm x 30mm discs which are pretty much the same size believe they are 320mm x 28mm on the a5? I know you can get the S5 carriers and then get the macan or q5 calipers but if this is an option as well may try this route any info please let me know.

Thanks

Joe

Someone tested this in a recent thread, did you search? From my understanding the 4 pot caliper from the Q5 will be an upgrade, but you'll also need the S5 carrier to fit the larger disc. Ebay seems to get you plenty of options, but if the caliper says Porsche on it it'll be quite a lot more expensive despite being the same manufacturer as the Audi uses for it's Macan brother. There are some variations to the caliper part number when I researched this, the differences still being undisclosed to my knowledge.

Do a search for the recent thread and I'm sure you'll find more answers and information.

Hi Joe,

Yes the 'BN' brembo 4 pot calipers are for the 320mm x 30mm discs, std on the 3,0 tdi.

The other version of 4 pot calipers fit the S5's 345mm disc. I am in the process of doing a small upgrade on my S5 using 8R0615105/6 BE Brembo calipers which fit the 345mm disc.

Note: the Brembo calipers do not have separate carriers, they are built into the caliper. Carriers tend to be for sliding calipers like the OE single piston caliper.

There are plenty of the 320mm disc Brembo 4 pot calipers and I think the sellers think they are the same and charge the same money as the bigger 345mm disc calipers. There has been a set of shiny black ones in Glasgow on Ebay for a while, but these are the 320mm disc type and I guess the only buyers would be Q5 owners looking for a direct replacement, although there is an advantage of 4 pots over the single pots fitted to yours, so even though the same size disc, it is still an upgrade, like it is for me as I'm staying with the same size OE discs.

Also my S5 calipers, same as the rest of the A5s, but with the carriers to make it possible to fit the larger 345mm disc will be up for sale soon!

As you can tell, I given this quite a bit of research, so let me know if you have any other Qs!

Also, you can get SQ5 caliper, that are a twin pot sliding caliper, but they allow you to fit 380mm discs!!
