Got my 2019 G63 last April. After about 10k miles my brakes started to squeal. I’m talking old school bus squeal. Was at dealer for 3 weeks sending recordings to Germany engineers etc. They changed pads with new adhesive. Was fine immediately after “fix”. Now about 4 weeks later it has started to squeal again. Always under light breaking typical of city driving. Anyone else got noisy G63 brakes? Thanks

 

after they replaced my pads and they still squeaked they replaced my disks and pads and the problem was fixed. Same thing happened to me. Something tells me that 2019’s have been sitting near humid areas I.e in Canada they were all on standby pending the late release date (emissions etc) so I’d ask them to replace both just an idea :p

 

yes---tell them to replace Pads and rotors....I chased a squealing brakes for sometime and this was ultimately the fix for me---Cheers

 

Interesting. Mine make noise too and I just thought I had to live with it. But if you are saying there is a fix, then I will try.

 

Back at the dealer. A technical case has been opened with MB by the dealer. This is what happened last time when it spent 3 weeks there. That time it was a new pad adhesive. Worked for about a month. Will see what happens this time. I have had 2013, 2017 and 2018 G63 without this issue. Only on new version 2019. I will update after MB gets back to dealer.

 

Sorry to learn this. Keep us posted!

 

How about some aftermarket pads - has anyone experimented with them? How much brake dust do the OEM pads generate?

 

G63 at dealer since Monday. Waiting for response from AMG I’m told.

 

I have the same problem. Did you ever get it fixed? @gotwire @Hrada2020

 

I have not taken my car in. But they still squeak.

 

Had pads, discs and “new” biadhesive replaced on all four. Better but still squeaks. Normal for AMG I’m told.

there was a new S63 at dealer service with same issue.

 

Need to take mine in as well.

 

I was also told that it is normal for an AMG. Not sure if that's true or why that would be the case.

 

I had a GLC63S prior to the G63 and it never squealed, so no, it's not "normal".

 

What do you think about bedding the brakes? I know that there is a LOT of confusion about bedding brakes (especially over at the Ferrari forum). Bedding brakes is VERY important if you have ceramic brakes. but I don't know if it's as important for steel brakes? Ask Mercedes (or the AMG folks) if they have a preferred bedding process?

 

My 19 G63 brakes squeal like there’s no tomorrow. My F car with ceramics also didn’t sound fantastic either. At least the Gs breaks can still perform well when cold. Would hate to see a G with ceramics try to stop in the cold....

 

Generally, brake noise originates from vibration within the wheel end section
Different type of brakes noises are:
• Grinding
• Squeaking
• Knocking from the rear
Any problem related to brakes might be dangerous to you, so I suggest you to kindly contact any local mechanic.

 

Another data point - my 2020 G63 also squeaks/squeals at low speeds occasionally. I think it is normal - drove around Beverly Hills today with the sunroof open and heard plenty of other G63s (2019-20) making the same noise lol

 

My 2019 G63 with about 4,000 miles is squeaking as well. Funny enough, I'm in Beverly Hills as well so you might have been hearing me haha.

 

you hear the sequel while braking or just low speed rolling?

 

It's not consistent and occurs when braking lightly at low speeds. Never when I'm really stepping on it.

 

okay, same issue that I have. Got over 7k miles. I hated it when my bmw squealed at low speed rolling but owning Porsche 911, this brake squeal while lightly braking is a non issue for me - it’s common on Porsche with high performance brakes and same case here with g63 imo

 

Same issue. Would be great if someone with a 2019 could post an image of the dealer fix notes. Doesn't really bother me but at the same time if there is a fix I'd prefer to avail myself of it. Wouldn't mind some free new rotors either

 

2020 G63, My brakes starting squealing at 5k miles. Super embarrassing as it is so damn loud. I drive through Hoboken, NYC, etc and people turn heads not at the G but at the loud screaming brakes. I need to bring in soon.

 

My 2020 g63 and my 2014 911 with PCCB’s tend to squeal a bit...My 2015 g63 never squealed. For the 2020 g73 , my MB dealer replaced rotors and pads on my 2020...my SA is world class and just get things done...not sure if MB wants to do this on all G wagons.
I hate hearing the squeal of any car , especially mine. One trick I use is to spray my brakes with water when cold ...let them dry a bit with surface oxidation ...then I drive forwards and backwards @ 30 yds or so with heavy brake and slight amount of throttle to scrub the rotors in both directions ...my neighbors get a chuckle ...lol.
In any case, this tends to eliminate the squeal for some time (usually @ 5-10 days ). It’s a workaround and both cars tend to fight this strategy by cutting throttle when I apply brake at the same time ..but the cars allow me to do it briefly ....PCCBs on my 911 tend to squeal with weather changes ...humidity etc ...

Cheers-
