Fronts done at 45k miles under warrantee
Fronts again at 96K miles myself, $820 for the parts from Audi.
Fronts and Rears at 138,000 miles. $1000 for all four, partsgeek.com
Brakes done at 73 k and 116 k miles. The dealer must have done them some time around 35k ,but I did not see a record of that, I'll have to check again.
That is not bad life on the brakes and rotors.
