I’m hearing squeaking breaking noise from my 2017 GLE63s. No warning signs on dash yet.
Checking the rotor, there is a definite outer edge lip. The pads seems to have life left.
I recently had the worst experience at Manhattan Merc dealership and I don’t want to return there. I remember someone saying AMG rotors cost up to $7k per wheel. I’m assuming he was quoting for ceramic rotors? Online I’m seeing $2k ish for all four.
Few questions for the forum. Are there better after market rotors I should look into?
Studying rotor replacement vids, the installation seems to be at DIY level.
Try doing a series of hard stops. Often the pads develop a glaze and then squeak.
Like, HARD from 60-5, repeat. The hard part is finding a place where you won't upset traffic or get arrested - 90-5 is better, but it takes some room.
There are numerous brake threads on here if you do a bit of a search. Check out FCP Euro for brake kits. They also have lifetime replacement warranty. They have better rotors from Zimmermann, Brembo etc. for far cheaper. I've got their kit for both front and rear on my C63. The fronts are upgraded Brembo full-floating rotors that were used on the C63 Black Series and the GT R. The AMG brakes tend to start squealing once the pads are close to be worn. It's an early sign. But they can also squeal for lack of properly bedding them in and not using them enough. Performance brakes need to regularly get some heat in them to maintain the pad material layer on the rotors. Normal mundane daily driving scrapes that layer off or never builds it and then the pads scrape against bare metal and underperform. Good video below on the subject.

I tried to pump on the breaks and the noise stops for a bit but reappears. I'll try to make 50-5 happen. Might be a challenge in NYC but will try to find an alley.
A couple of thoughts, without knowing your mileage...
I've always found that performance oriented pads, once temps fall below 20 or so, will begin to squeal. Does it occur on a 50 degree or warmer day?
If the rotors have over 50K on them, OK...maybe they're the culprit but squealing is typically a function of the wear indicator on the brake pads making contact with the rotor. It's a strong bet that the wear indicator probably won't begin making noise until AFTER your in-dash indicator lights. I don't know for certain but would believe the in-dash indicator lights with 3 or 4mm remaining. The pad wear indicator probably makes rotor contact at 2mm.
The lip on the rotor is no big deal, what matters most is the remaining rotor thickness. If you want peace of mind, have a trusted brake shop measure your pad and rotor thickness, it'll answer your question pretty quickly.
Thank you. I've been seeing the brand you're mentioning. I'll look into this.
Did you install the replacements yourself?
No, I had my indy install it. I did have to help them, though as they couldn't figure out how to get into the workshop menu and retract the rear pistons. They were trying to do it from a laptop, but that didn't work
I did this exact service about a year ago. Brembo makes an aftermarket rotor for front and back. Don't use their front pads, I had bad glazing and very uneven ware. I bought a set of HAWK pads for the front and Akebono for rear.

Thank you.
You can easily do 50 on the west side highway at night and plenty of lights will make you stop.

Good luck!
From what I noticed, the noise occurs in all temps. Good to know the wear tolerance before the warning light. Thank you.
