brembo front caliper ; same on 2.0 and 3.0 ?

Hey guys, looking at the b8.5 Q5, is the front caliper the same brembo caliper despite the different size in rotor ?

thanks !

They are both 4 piston front calipers that use the same brake pad. If that answers your question :D

So I suppose then they are in fact the same, just 2 different size of rotor... Not sure why audi would do that, just cost more to produce 2 set of rotor than just one lol.

Yeah I'm with you - but they probably sell 90% + non 3.0 around the world and use those same rotors on other cars so it might actually make sense from a cost perspective. I've actually seen some 3.0s in the lower trim levels with the smaller calipers as well.

Btw, the calipers have the 'carriers' built-in, so you can't just replace a carrier to run the larger rotors unfortunately.

I'm hunting for a set myself. Already picked up the appropriate rears.

thanks for the link !! it's now very easy to spot... if it has a hole its 345mm.. if it doesn't have a hole between the 2 mounting point, it's a 320mm ! :)
