Rear Brake question
So we had service A at 8500 miles. I was recommended rear brake service that I declined as I didn't believe I would need REAR (not front) pad replacement after so few miles. Sure enough it seems I am near the end of the rear pads.
I am aware of MBs quick rate of brake wear in general and expect to service brakes at 20-30k miles.
This made me curious as this as well as many new cars apply brakes automatically for traction etc. If there should be a bug in the traction software that applies too much rear braking, a premature brake wear is eminent.
Anyone else has noticed this excess wear of the rear brakes and thinks that it may be other than normal wear and tear?

just had the vehicle serviced for the first time today and, same thing it was an A service and they also recommended replacing rear pads as I only had one millimeter left he said the front brakes will probably need soon and also tires soon after. this is starting to get expensive quick.

It is not normal for rears to go before the fronts. Even if you consider the wear and tear higher than non AMG.
That is why I have this theory that the tears are overused by the cars electronic nannies.

This makes a lot of sense. I am at 24k miles and need rear pads and rotors replaced. I have all the electronic features on. The SA was also baffled by the increased wear on the rear vs the front. He said he sees that a lot in the GLs...?

The AMG braking mechanism is balanced so there isn't the dive effect. However, I've had rear rotors and pads replaced by 10k on all W166/X166 models over the years. We found it to be tied to the parking brake and I have never paid a dime for the replacements. Push back on your dealer.

That may be a tough sell...I’d appreciate any advice or info that might help with that.

They should submit as such. All I can tell you is that they did it for me on more than one vehicle. As a follow-up, my dealer replaced them under warranty last month. Good dealers realize this is an issue and take it up with MBUSA. Three different vehicles, $0 out of pocket.

Hello, everyone:
Just wanted to share my experience. I used to have a 2014 ML 63 that was in my possesion from late 2014. In October of 2015, at less than 10,000 miles, it required rear brake pads and rotors. As this was a lease, and I didn't want to spend money on a vehicle I was not going to keep, I called my dealer to order a new 2016 GLE 63 S. I took delivery of that one in December of 2015. Last month, at 7700 miles, it called for a B service, and the dealer informed me that I needed rear pads and rotors...again! As you can see form my signature, I've had other AMG's throughout the years, some of which I've taken on the track, and none of them needed brakes so early. I don't know what it is, but it seems to be a recent thing with AMG vehicles. My GLE 63 S was never taken on the track (sadly) and it didn't engage the lane keep assist very often, I don't know if the brake bias on these vehicles is adjusted more toward the rear to prevent nosedive under normal braking, or if there's something else going on. That's my experience, for what it's worth.

Its not just a recent thing for AMGs.. Most of the models have been doing it for the past few years. No idea why and nobody I could ever get ahold of would give me any kind of answer. As for replacing the rotors, that seems absurd unless you went metal to metal and started grinding the rotors with the backing of the pads. Honestly, you all should talk to the service writer and get the technician to show you the parts either before or after they are replaced. There is WAY too much greed in this industry right now and the dealerships (technicians) are not immune to this. Very few actually measure anything. Very few actually remove the wheels to inspect inner and outer pads. And the service writer.. he/she is just a messenger who knows nothing more than what some 18 yr old kid told him to sell to you.

The floating calipers seem to be less durable in terms of pads and rotors. Further the rear brakes are very busy with your ESP. More than you know and feel they are braking as part of lane keep and attention assist etc. 166 platforms are bigger cars and put more wear.
