E53 brake pad & rotor wear after 9700 miles
I removed the wheels today to do a thorough cleaning job. While the wheels were off I inspected the brake pads and rotors. After nearly 10K miles both the front and rear rotors are only worn about 0.1mm. There is barely a ridge on the edge of the rotors. At this rate, the rotors will last over 100K miles. The front pads are down to 11mm and the rear pads are at 9.5mm The pads will also make it to 100K miles, but the sensors will probably be triggered between 80K and 90K miles.

Speaking of brakes (and the E450 in particular), does the cruise control use brakes to control the car's speed? I know it uses battery charging, but at some point are the brakes used. My V90 Volvo used the rear brakes (no charging) which caused a very noticeable brake pad wear for the rear wheels.

W214 E450
My 2025 E450 had the first service done at 9,744 miles and front and rear brake pads were measured at 10mm. The mild-hybrid models also have regenerative braking and I expect them to do well on brake wear as well. Maybe even better due less weight. I'm not sure if it will last 100K miles though. I guess we will have to wait and see.
How do you know your rotors have worn 0.1mm? Did you measure them new?

I suspect that the 10mm measurement provided by your dealer is an eye-balled nominal measurement, not an actual one. The initial thickness for the front is 12mm and the rear is 10mm. It's unlikely that your front pads wore down 2mm while your rear pads did not wear down at all. It's interesting to note that new rear pads on my EQS SUV were just under 8mm thick. The W214 pads are probably shared with other MB ICE vehicles so MB did not use thinner pads like they do on a BEV. These measurements are probably not relevant to an E350 with smaller brakes.

Yes. the base front brakes (370mm rotor) are 36mm and the rears are 26mm. Minimum thickness printed on the rotors is 34/24 for front/rear rotors.

Maybe related, but only at 300 miles...
My 2025 E53 wheels or brakes were humming at a cadence that matched the speed I was going. Whoosh, whoosh, whoosh was ever-so-slightly heard echoing off nearby curbs/barriers and it was clearly coming from the wheels or brakes on both sides of the car. Brought it in for inspection and the head technician went for a test with me and agreed it was likely the brakes. They've done some stuff, but it still happens when they test so they may replace the brakes. While sanity checking they've now noticed other W214's at the dealership will also do this. They didn't specify whether those W214's were E53's with the Dynamics package (390mm front discs). Stay tuned for the outcome.

Side story: Turns out the OEM MB dash cam (which turns on automatically) showed 2 days of inspections (inside their garage), tests in the parking lot and on local roads, more inspections and tests. I even saw some of the other W214's they tested. Impressed with how thorough it all was. Only downside to checking footage: I asked them to NOT WASH it as they use a touch washer with brushes. You guessed it. The person transporting from their offsite garage to the dealer ignored the "NO WASH" sheet the service manager put on the seat and ran it through the onsite touch washer. For most people this is probably a bonus. For an uptight AMG owner like me I was sad. My paint will live, I got over it.
