Mine just turned 45k miles. I checked the rears and the surface definitely does not need replacement, but I don't know about the "warping"

Audi said 3mm left on front and 4mm on rear pads.

I have the sport edition, so based on AllData, these have 380mm rotors, rears at 356mm. (I also measured to confirm)
I've sourced the OEM rotors & pads, and my brother has access to a lift, so thinking I can get this done myself.
AudiParts.Com : $1356
AudiUSAParts.com: $1513 (shipping made this much more expensive)
FCPEuro.com $830 ???? With lifetime guarantee?? (guarantee includes rotors!) aeggroup, I noticed your ebay posting looks like the same as FCPEuro, but if you buy from them, it's guaranteed for life.
https://www.fcpeuro.com/page/lifetime-guarantee

Anyone think the FCPEuro these would be an acceptable option?
Here is a link for the front kit. https://www.fcpeuro.com/products/clo...at-4h0615301an


Thanks for all the help

I would call them and ask if it applies to rotors and pads.

Yes, FCP's warranty covers rotors and pads. The catch is you have to mail them back to FCP in order to get your account credited.

I've used their warranty before on a rear strut and control arm.

Good luck.

I went to a 3rd party Audi repair shop yesterday to check to see if they would do the labor on the brakes. They said sure. The service tech said it's $500 because it requires a "special" tool.. Price was not toooo bad, but I"m laughing about the special tool. It's just the VCDS/Vag-Com to unlock the parking brake.

Parts are ordered from FCPEuro. With tax & shipping, $907 for 4 rotors, pads & sensors. Zimmerman rotors & Akebono ceramic pads. Not bad if I do say so myself.

Just a heads up, the front brakes on a 2015 A8L are EASY!! Tires off, 2 bolts holding the calipers, 1 nut holding the rotor, 1 nut holding a cover that holds a spring. THAT'S IT..

After I worked through the first one, the other side took me less than 1/2 hour.

It took me longer to do the break in.(for the second wheel) (30 separate brake operations 100km-> 50km, then 100km -> 25km with 3 minutes in between for cooling).

My only difficulty was removing the rotor. Rusted/frozen in place. I tried a plastic/rubber hammer, a regular hammer, then a sledge hammer .. The last hammer worked. I added anti-seize on the hub so that the next time it might be easier.

If anyone is questioning if they should do this, and you have some basic mechanical skills, I would definitely recommend doing it yourself.
Thanks for all the advice and help, saved me about $1800
