Hey guys Im new to the forum, this is my first post!

I have a 2005.5 B7 A4 Quattro 2.0TFSI, my rear brakes need changing I just replaced my front brakes about 10 - 15k miles ago. I Just purchased the tool for compressing the rear piston, now I need to figure out what size Brake Rotor I have?? Yea, They say Audi makes several sizes and Im clueless. I called audi, but the guy didnt seem to know, and recommended putting it into service for them to pull the rim and measure my rotor. ( yea ok-- sure! )

I dont remember having this measurement issue with the front rims - maybe I just lucked out and purchased the exact size pads? Any help / Suggestions?

Thanks guys!

 

288x12 on the rear rotors

 

Did you get the right compressor - one that rotates the piston as it compresses? akaEsCo01 is correct on the rotor size. Both the 2.0 and 3.2 use the same brake pads, but I have found that in order to get the correct pads for both the front and rear, I usually have to look at 2006 quattro pads, especially for the rear. Front pads are also the same for the 2 and 3.2.
