Hello, I would like to change my brake pads but I don't want to use OEM since it makes so much dust when it comes to every week of braking.. What brake pads are compatible and good for the GLS?

I heard the product line "Redstuff" is good but not sure if it is available on the GLS.
Oh thanks for the replies, but will this guarantee to fit for the 2022 GLS 450? Are brake pads universal or are there different sizes I should know? I'm new haha sorry.

You're welcome, happy to help. To be sure though I recommend asking them by calling them or emailing them. That is the safest way to confirm if it works or not, they might ask for your VIN.

Brake pads are not universal. Even the same model car will have different pads depending year and options.

Ohhh okay, I found that Powerstop Z23 is compatitble with the GLS so I will have my mechanic install those. I also need new rotors for the front. Has anyone did their brake pads and rotors and care to share how much they paid?

I've have my mechanic installed the PowerStop Z23-2237 Brake Pads and it's compatible and rotors I got OEM from eBay cheap for $197 each! Just as new and no issues! I hope this help with others. I love these ceramic brake pads. Barely any brake dust!
I used the Powerstop z23 pads but had a lot clanking type noises when hitting bumps afterwards from the pads moving. I reinstalled them last weekend using the same 3M adhesive backing the OEM pads use and also re bent the fingers on the retaining hardware so they locked in tighter, so far things are better. Way less dust but obviously don’t bite the same as OEM.

Where did you get the 3M adhesive, is there a part number or do you just buy a sheet and cut it?

It comes from the 3M VHD line which contains a ton of different adhesive products. 3M appears to rate a small set specifically for automotive brake applications - https://multimedia.3m.com/mws/media/...umentation.pdf
I found 3M F9469PC in 1/2" width for $10 a role on Amazon. I used a lot of CRC brake cleaner and towels to clean both the back of the pads and also the mating surfaces on the calipers (pistons on one side, caliper fingers on the other). After the pad backs were all clean and dry, I carefully completely covered the pad shims with with the adhesive tape and reinstalled.

Thanks I may change the brake pads to the power stops, as you know the amount of dust is insane.
Do any of these ceramic pads feel as good as stock though? Overall, I'm really impressed with the factory brakes, especially considering how heavy the GLS is
Lol. I should have known that wasn't enough infomation.
It's front only and it's rotors and pads. It appears it comes as one unit from mercedes for both wheels according to how it is line item'd in the estimate. I was interested in aftermarket pads and rotors but given the last of information in the web in relation to this for the X167 I decided to just go OEM. I am still interested in hearing about those who have used non OEM parts for their brake systems.
They absolutely can do just brake pads without replacing the rotors. I would guess that the part number provided for the brakes+rotors is something that your MB service department has created. Our service department has similar customer part numbers for bolt kits and maintenance supplies (lubricants, cleaners, o-rings, small things like that).
I have yet to have a MB dealer offer just brakes when recommending the job. You have to specifically ask if the rotors are warped, etched, overly rusted and require replacement. Getting repeatedly screwed over on brakes was a big driver for us to start doing our own maintenance. The dealers were telling us to replace brakes and rotors without telling us how much pad was left or if the rotor was warped or etched. The last time we were told we REALLY needed new brakes we still had more than 8mm left. They weren't going to tell me until I specifically asked to see the inspection report...which they also didn't want to give me.
I suppose it's possible that they could be packaging rotors and pads and associated pieces, and discounting it. They might be overstocked on something.
I would definitely ask if the rotors are out of spec in any way. Thickness and run-out at least.
Sometimes they can be turned and still remain within spec, although I wouldn't argue with a shop that says turning rotors is against their policy. I'll bet they have a few comebacks on turned rotors.
Once you know the thickness you can estimate how many miles you can expect, total, on the discs. You don't want the discs to go out-of-spec before your next pads expire.
I may have missed it, but how many miles are on your brakes?
The Powerstop Z23 works for the X167 GLS and I got my own rotors OEM too, my local mechanic installed them for me and I just only ordered the parts. WAYYY cheaper than of course dealership. Only paid $120 for labor. After driving it feels just like OEM brake pads, no change or brake feel so far.
I wasn't sure aftermarket ceramics would bite or match braking distance of the stock pads. I ended up just having the dealership do the fronts. Pads and rotors were $700 parts and $700 labor and got 10% off. FYI the stock U29 sport brakes that come on the AMG Line 450 and all 580's are brembos.

I used the PowerStop Z17 Ceramics for front and back last time and they are just fine. A bit less initial bite, but not enough to cause any concern plus I'm an old man and drive like one . $130 total expense including two brake wear sensors.

That's awesome to hear, for me it's just perfect brakes perfectly good and fine no noticiable changes from OEM brakes and NO MORE HEAVY BRAKE DUST! I'm extremely happy with the PowerStop Z23 and it's compatible with the GLS for those want to know. No squeaks or lack of bite at all from light braking.
Rather than start a new thread, a question about my situation….
My 2020 GLS450 was a special order and has the larger U28 Sport Brake System(SPC) option. When I look at the Powerstop website there are no subcategories for the standard or Sport Brake. I would assume a larger brake pad is needed for the Sport Brake, but don’t see that option. What am I missing? Please educate me. Thanks.

Can you cross reference anything to the MB part numbers? Does FCP euro offer correct brakes that could be cross referenced? Here is what CHatGPT said:
————GPT———————
Short answer: I (CHatGPT) can’t find any PowerStop pads that are confirmed to fit the 2020 GLS450 with the special-order U28 “Sport/High-Power” brake system (SPC). PowerStop’s pads that are sold for the GLS450 (e.g., Z23-2237 front, Z23-2210 rear) are for the standard brake setup and listings don’t indicate U28 compatibility.What does fit U28 (examples for reference)
Rear OE pad set: Mercedes A000 420 73 03 (aka 000-420-73-03 / A0004207303) — specifically called out as “for cars with High Power Brake System (Code U28).” Aftermarket crosses include Brembo P 50 161, Zimmermann 22723.190.3, and Febi 178655.
Why I’m (CHatGPT) saying no on PowerStop for U28
Many parts retailers explicitly exclude U28 on their GLS/ GLE pad listings (they separate “standard” vs. U28 fitment), and PowerStop’s own generic pad pages don’t show a U28-specific fit. The U28 package uses larger rotors and different pad shapes, so the common PowerStop sets won’t match.
If you want a direct replacement today
Go OEM using A000 420 73 03 (rear) or use one of the cross-refs above. For the front, Mercedes has multiple superseding numbers depending on build date; the safest path is a VIN lookup with a Mercedes parts desk to pull the U28-specific front pad part number for that exact car. (Retailer catalogs show this variation and often hide U28 under separate part numbers.)
If you still want PowerStop
I recommend double-checking with PowerStop using their Brake Finder (they’ll tell you by VIN/sub-option). As of now, their public pad/kit pages don’t list an application that explicitly includes U28 for the 2020 GLS450.
Want me (CHatGPT) to try to pin down the front U28 pad part number for that specific VIN or build date? I can hunt it down and then see which premium aftermarket brands (Brembo/Zimmermann/TRW/etc.) carry it.
————- End of GPT——————
As always double check any part numbers before ordering anything based on GPT, but this should at least give you some leads to pursue. Hope that helped.
