Hi there
i have a 2023 G63 with only 2600 miles. we intend to keep for a long time. The last Mercedes we bought was a gl450 2007 and I still have it.
long story short, we occasionally take the G out and last ride the brakes were squeaking at every light stop. It was kinda embarrassing. Car had 1000 mile service done , stays indoors. Should I not worry or go to a dealership?

 

Welcome to brembo/ other performance brakes .... most AMGs, most BMW M cars all suffer from the same nonsense.

Should you worry about it? I definitely worry about it. A lot. Not because theres an issue with the brakes, there is nothing wrong with them, but I definitely worry that they couldn't figure out a better design to make our $100-200k+ vehicles not sound like a uhaul rental box truck when coming to a stop light. This is only 1/2 the issues with these brakes...(notice I said brakes not G63 because its ALL) ... The other 1/2 of the issue with these brakes is the brake dust, it's absurd that these multi billion dollar companies couldnt figure out how to make this better with out spending 10-20K on carbon ceramic brakes.

You can try to go to a dealership. They'll likely just tell you "sorry, deal with it"... BMW when I did this actually handed me a pamphlet to explain why BMW and the dealer wouldn't do **** to help me with the issue.

It sucks. There is potentially some aftermarket pads that help the squeal and less brake dust. However, even with the aftermarket pads, there is either trade offs on performance, or noise or both.

I have a 2019, same brakes. I installed "disc Italia" pads and rotors, and so far they've been good. The feel of the brakes is the same as OEM, stopping power I dont notice much difference, the dust is still present, but a lot less, probably 60-75% less dust. Squeal is better, but sometimes still there at times. Ive had these previously and quality doesnt seem to be an issue, and ive had no issue with pads or rotors from them,

Below is the cost, and parts I ordered from Brakeworld.com, then had a local independent shop install them all for about 700-1000.00 so the entire 4 wheel brake job was 26-3,000.00 which is substantially less than any dealer quoted. By substantially I mean like 1/4-1/3rd the price a dealer tries to charge.

Just be aware that aftermarket pads and rotors, will likely not be warrantied by MB USA, and could actually affect your overall warranty on the brakes system. My car is not under factory warranty anymore.

Not much options other than aftermarket which may or may not improve the noise, dust, or performance.

 

My 2025 G has a faint squeak every now and then, so did my 2024 911, so does my sisters SQ5, so does my parents GLE450. Oddly enough, the KIA rental car I had was dead silent LOL

 

That sucks bad 😀. I am just going to assume that I am listening to bad music for now . Haha

 

Had same issue on my '24 Gwagon. Specially in winter months lol.
On my '25 nothing so far

 

I was just wondering if anyone with a G550 had this issue since we do not have the Brembo brakes used on the G63 AMG. I have not had any squeks in my 3,500 miles since May whenI took delivery. I had wondered if this was just part of more high-performance brakes? I never had this on previous vehicles except for a 2002 Land Rover Discovery - then again I did not keep them too long. My 2018 Toyota Land Cruiser 200 series has 50,000 miles now and never had a problem.

 

Hey Angus,

As you know I have a 2025 G550. My brake squeak started maybe about 6 weeks ago, like another mentioned above, it could be cold weather related, I'm still in NC. I have 4300 miles on the G, don't ride my brakes...Mine only faintly squeaks a tiny bit when I come to the last 5 feet or so of stopping, only heard in the garage, can't hear it outside even with window down.

I think I will lemon law it!!!!! 🤣 (kidding of course)

 

Unfortunately there is no specific condition that causes this, not cold or hot. I live in Arizona, and it happens in the dead of summer 120 degrees, and happens in the winter when the mornings can get in the 30s and 40s.

Also, they tend to squeal less when brand new, or freshly dont brake job, but it alwasy seems to return after some time and miles no matter what.

 

Here's the deal, I JUST went through this with MBUSA. I bought a 24 and the brakes squeal once in a while. Sometimes I'd drive it and noting at all, like they fixed themselves, and other times its unbearable. I've had a dozen "high performance" cars and they all do it. My wifes new 24 RR Sport is whisper quiet but it required a rear pad and rotor job at 10K miles; LR saying they focus on quiet and comfort thus pads and rotors are "softer" than high performance variants.

MBUSA does step in to help, but I learned a very valuable lesson in the process. Dealerships have two avenues of helping. One is their own pocket, and the other is the MBUSA corporate war chest. How much they "pull" from either comes down to relationship, and more important dollars spent at dealership. While I've serviced all my MB cars at the local dealer (out of convenience and warranty), I haven't purchased a single one from them as their pricing is preposterous. Therefore, they were unwilling to reach into their own personal war chest, and only pulled from the MB reserves.

And there is the big problem. MBUSA will step in and offer assistance, there's no denying that, but it does with strings attached. The only way they offer it is if you do the work at an authorized MBZ dealer. Cost of pads and rotors at dealer is $10K+-. MBUSA assistance is $2K. Total cost = $8K to do the job. So basically, you're still paying about twice the rate for the same job (with arguably better parts) getting it done at an indy. Which is exactly why on principle I refused the assistance and when I need a replacement will get it done at the local MBZ indy.

Also important to note. I've been told by my SA and a highly trained AMG tech who I know outside the dealer that even if you replace pads and rotors at the dealer you'll be right back. You are literally replacing squeaky parts for brand new parts with the same part numbers built in the same factory using the same processes/materials. They will squeak.

In trial and error, I did find my brakes do not squeak after a car wash. It seems knocking the dust off seems to help. Also, they squeak way less when they're cold. Mine only squeak when they're super hot like after a long drive etc..

 

I'll add that on my M5 when the squeal would happen... There was a recommendation to bring the car up safely to 60-80MPH and slam on the brakes until stopped. Do this 3-4 times.

It does work...

However.... It tends to work for the remainder of that drive or when the brakes are still warm but it returns right away at the next drive. Or at least that was my experience...

So basically to clean the extreme brake dust off the wheels from those hard stops, you wipe down with rag, or wash the wheels, and while cooling the noise returns LMAO... Classic.

 

This is a common issue on AMG brakes. Happened on my C63. I was also able to fix it by slamming on the brakes hard to ruff up the disks (remove glaze). But it will come back. I think some G63 owners were actually able to lemon law their car for this very reason (seems a little crazy). Anyways - seems it's pretty normal.

Somebody else had asked if this happens on the G550. I have had a 2021 and 2023 and can say that I have not had brake noises on either. I think this is only on the full AMG. Hope this helps...

 

Honestly one of the reasons I opted for the G550 as a daily, along with the cost of replacing those squeaky brakes.

 

fun of driving a 63 with occasional squeaky brakes always wins driving a 550

 

Agreed. I understand that they look similar to the untrained eyes, but I personally would never put the G63 and G550 in the same category. The former is a performance-oriented AMG, and the latter is a Mercedes. That having been said, I respect that different needs/wants for different people.

 

I had a 2020 AMG G 63 for four years, and the brakes never made any noise at all. I traded it for a 2024 AMG G 63, and I currently have 26,000 miles and the brakes have never made any noise. Tons of brake dust (horrible), but no noise.

I went to perplexity.ai (they call themselves an AI-powered answer engine), and I asked the following question:
What is the best brake pad compound to reduce squeal on AMG G63 brakes?

They came up with some information that might be a reasonable solution. I'd contact an independent Mercedes service shop with a good reputation, and I'd ask them about brake squeal and "street performance" pads (whatever that is). I could live with street-performance brakes because I drive my G 63 like a normal truck (not a race car), but brake squeal would drive me crazy!


On AMG G 63s, moving away from the very aggressive, high‑metal OEM pads toward “street‑biased” ceramic or low‑metallic compounds is what tends to reduce squeal the most. The trade‑off is slightly less ultimate track performance, but for normal road use most owners find the noise reduction worth it.​

Pad types that usually squeal less
Ceramic “street performance” pads are generally the quietest option, because they use less metal, generate smoother friction, and produce finer, less abrasive dust. Low‑metallic or semi‑metallic “comfort” pads with reduced iron content can also cut squeal compared with full high‑performance AMG compounds, though they are usually a bit noisier than ceramics.​

Example aftermarket options
Many G‑class and AMG owners move to ceramic‑based performance pads (for example, EBC Redstuff or similar “low dust / low noise” lines) when they want quieter operation but still decent bite for spirited street driving. These types of pads are marketed specifically as low‑dust, low‑noise upgrades for heavy, powerful European SUVs, which aligns well with the G 63’s use case.​​

Other things that matter
Even with a quieter compound, proper installation with fresh shims, high‑quality anti‑squeal paste on pad backs, and clean, de‑glazed rotors is important to get the full noise reduction. Keeping pad edges chamfered and hardware lubricated at all metal‑to‑metal contact points also helps stop the high‑frequency vibration that becomes audible squeal.​

Practical recommendation
For mainly street use and a focus on comfort, a name‑brand ceramic street‑performance pad set (front and rear) plus fresh hardware and anti‑squeal paste is usually the best balance of reduced squeal, low dust, and still‑strong stopping power on an AMG G 63. If maximum track performance is not a priority, this is typically a better solution than repeatedly rebedding the stock pads, which often remain noisy by design.​
