Do you have a source or link for the Brembo NAO Ceramic pads for the W166 GLE 63 s and a recommendation for rotors? Thanks for the help!

FYI - I fitted the Brembo rotors and Ceramic pads 11 months ago. I followed the bed in procedure to the letter. I also flushed brake fluid at the same time.
This is after 7000 miles... Both front rotors are damaged like this. Back rotors are fine. https://cimg8.ibsrv.net/gimg/www.mbw...89f68edcfb.jpg https://cimg9.ibsrv.net/gimg/www.mbw...399f04aa60.jpg https://cimg3.ibsrv.net/gimg/www.mbw...18cc527883.jpg |
No brake expert here, but this does not look good. Original Brembo, right, so.... what could have caused the pad to wear down so quickly I wonder? Bad mfg batch perhaps? Foreign object stuck in there? Purchased at Brembo or another site? I'm just trying to learn.... I still have approx 50% pads left and am watching for when I need to replace them later this year (30k now on the clock). I am undecided if I will DIY or take it to the dealer. I have the Dynamic Plus pkg with the U70 red brakes.

Ordered via Brembo Front & Rear Brake Kit PVT Disc Rotors Ceramic Pads For MB X166 W166 W167 | eBay
Genuine Brembo. No idea what caused the wear and breakdown of the pads. I don't do a lot of heavy braking but had to the other night and it was scarry. Pressed the pedal has hard as I could, and it felt like the it didn't slow down much and like there was no bite from the pads on the rotors. Ordered HAWK Performance Ceramic to replace the pads. |
It looks like a heat issue on the discs.
When you said you followed the bedding instructions to the letter, did that mean not coming to a full stop, but mostly giving time for the brakes are cool a bit? |
Yes. I did the warmup. then 10 slowdowns with 2 minutes at 30 in between and then once completed drove for 30 minutes with no heavy braking. Once cooled down I stopped and checked all 4 rotors, and everything looked perfect. This issue only seemed to be visible after a heavy braking incident, after that I could feel the brakes not biting.
