E550 Brakes and Rotors -- Front and Back
Front Brembo rotors and pads are not a suitable replacement for the W212 E550 since they start shaking again after awhile, in my case it was around 4k miles. We had to drive today and I could definitely feel and see the steering wheel shake under light braking, the worst feeling would be around 40 to 30 mph. I've also looked at the rotors themselves and there seems to be some sort of heat related little dots on their surface .I will be returning them to Autozone and try and figure out what to get next.

I also saw something about resurfacing drilled rotors. This is usually not feasible as it can chip the surfacing at the holes. Factory drilled rotors are often cast with the holes which are given a slight chamfer at the top. Aftermarket are often just drilled without a chamfer. Either way the grinding surface can nip at the surfacing at the holes and cause some damage. Just me, but other than looking nice I don't have a lot of use for drilled rotors on the street, thus my change to solid rotors on my car.

went with centric premium rotors and duralast pads(more expensive ones from autozone) and everything is smooth for almost 2 years.
p.s. i wish i woulda went with pagid or textar pads (which are oem) but duralast keeps it cool and dust free so maybe next time.

$115 pads
$260 rotors
$8 sensor
$95 labor
$478 plus taxes for total
Rear:
$70 pads

I also think proper lug nut torque and sequence is very important. Seems like every time I get the car back from service that required a wheel to be removed (say rotating the tires), the torque is all over the place for the wheels. Like they just rapid fire the impact wrench with no regard to setting.
None of the pads come with wear sensors for these that I have seen. VW has theirs integrated, therefore included. These have a pinhole for putting one into, presumably if it didn't make rotor contact you can re-use it. $10 ea locally, $5 online.

I too have the 2014 E550 tuned to 575/700. Installed Porterfield pads maybe 4,000 miles ago. Worth the money ($300.) over the MB stock pads, as they heat up they get gripper. However, today, as I was doing a couple of high speed, (85>100) slowdowns I got a wobble. So from here, maybe I'll do the rotors. As to the solid rotors you mentioned not sure where to purchase those, maybe here; https://brakeperformance.com/brake-r...nc-coating.php . An option I am very tempted to go to is here; https://www.racingbrake.com/Default.asp but 1100 bucks is a hit.
What's your thinking?
You got the tune huh? I’ve been thinking about it but have been told different things regarding the long term reliability. I literally drive about 40k miles a year so am worried a tune will hurt longevity of the engine/tranny? I met a guy online who is selling his 14’ E550 and said the tune he received doesn’t let the car start in 1st gear to protect the tranny. It seems the AMG’s use basically the same twin turbo V8 just slightly tuned with a few transmission variations, air intake, brakes, exhaust. Any thoughts on long term reliability/longevity?
This is the shop where I had my tune done over a year ago https://www.pressertech.com/mercedes-tuning-blog/ Most importantly reliability of engine and transmission. This is a major concern for all of us. My tune is a stage 2 and the reliability of the engine and transmission will be dependent on how I treat my car and not on the tune. The tune is nothing more than allowing the vehicle to perform at the optimum power levels designed into the motor and transmission by MB. MB is a performance-focused builder of cars but in their worldwide markets they have to take into consideration their buyers are not all gear heads. Basically, they de-tune their motors. We have to keep in mind this brand is based in a country where there are roads without speed limits. Just go on U-tube and watch people pushing their E-cars above 150mph.
As far as not letting the car start in first gear I had not heard of that before. My tune has not changed any factory settings as to driveability. The first thing you will notice is in 60-70 mph passing. In stock sometimes it would downshift, now between the hp and torque it hardly downshifts unless I want to make a point of passing at an ungodly speed. In a nutshell, the first time I floored it entering the interstate on-ramp I had to back off immediately or hit someone. It was kind of scary and the wife is not into high-speed driving. If you keep your foot out of the radiator you may get better mileage, because the rpm's will drop with the increase in torque.
I maintain peak performance by changing the oil every 5K with Mobil 0-40 European, plug changes every 50K, clean filters every 5K, (using Green reusables) and that's about it.
Keep it between the lines and happy motoring.
2013 e550 85 k.....
Replaced OE rotors at 44k due to shudder😭 , bought vented Zimmerman's and brembo pads. I have logged 40k ön them with no issues. All stop and go no racing or track use. They dust a fair bit but feels confident when hauling the speed down .
Just my two cents

I work for a Nascar team, and on a short track with lots of braking, the rotors will be warped by more than .010 after 2-300 miles.
Brakes take about 30-45 minutes per axle, and everyone should be doing their own. I don't even bother to put a car on my lift to do brakes. You have to learn to do this very simple maintenance item.
