i ordered pads and rotors for my 05 (built in late 04) s4. i get everything and get the pads off and quickly realize the pads i bought are the wrong size (see pic). I think no big deal, i'll get the rotor replaced and just take a buddy's car to get the right pads. but then my rotor were too small too. i'm assuming that since this year of the s4 was changed mid year that there are two different brake set ups yeah? my problem now is finding out where to purchase the correct items so that i dont run into this issue again. any ideas or help is greatly appreciated.

 

The part number for the rear brake rotors is 8E0-615-601R
The rear brake pad # is 4B3-698-451A.
Those look like some of China'S finest crap from Autoblown!

Do you self a favor & get german made Quality parts.

BTW there are Audi parts suppliers on this site that are sponsors.

 

thank you m5s5. i'm currently looking for better parts as well as hopefully the right parts!

quick question on the rotors however. the part number you gave me is for a 300mm x 22mm rotor... the ones currently on my car measured out to (and i know this next word is bad) about 321mm-324mm.

 

I am showing the rotors as 300 mm. They also show they fit from 04'-08'.
Maybe larger aftermarket brakes were installed? If they are factory they should have a part # & size stamped in them.

 

yeah, i was wondering the same thing. i've only owned the car 4 months and have no previous info on it such as aftermarket parts. only standard service records. thanks again, i appreciate it.
