Hi threeMBs,
Thanks for an excellent post. This is the exact information I have been looking for to upgrade my 2015 ML500. I can source used calipers from a donor ML63 (everything else I'm doing new of course). My questions are: 1. is there only one size of caliper on the ML63 ie are all ML63's 390mm? 2. Is the part# printed on the caliper (for confirmation when I go buy them)?
Thanks.
Hi threeMBs,
Thanks for an excellent post. This is the exact information I have been looking for to upgrade my 2015 ML500. I can source used calipers from a donor ML63 (everything else I'm doing new of course).
My questions are:
1. is there only one size of caliper on the ML63 ie are all ML63's 390mm? YES (at least for US market).
2. Is the part# printed on the caliper (for confirmation when I go buy them)? NO.
Thanks.
I have just completed full conversion of my GLE43AMG brakes (same brakes are on ML550) to Silver GLE63AMG brakes (same brakes are on ML63).
Following is a full list of parts with part numbers (some of the info is well known and some is less so) required:
1. Rotors:
A. Front 166-421-05-12 MB OEM or 09.B805.11 Brembo(this is what I installed) or 400369820 Zimmermann
B. Rear 166-423-05-12 MB OEM or 09.B710.11 Brembo(this is what I installed) or 400369920 Zimmermann
2. Calipers (Silver):
A. Front (Brembo): 166-421-28-98 and 166-421-37-98
(FYI Red calipers p/ns are 166-421-40-98 and 166-421-41-98).
B1. Rear (TRW/OEM): 166-423-07-81 and 166-423-08-81
(FYI Red calipers p/ns are 166-423-09-81 and 166-423-10-81).
B2. Rear Brake Carrier Brackets: (2) 166-423-06-06
(FYI Red brackets p/n is (2) 166-423-07-06).
(MSRP difference between Red and Silver is $1,100 or about $750 discounted on-line).
Calipers include all hardware required to install them, except for mounting bolts:
M14 front p/n 019-990-56-01 (2 required) and M12 rear p/n 018-990-00-01 (2 required).
Do not re-use your current mounting bolts! These are one time use items.
Transfer your current rear parking actuators to new rear calipers.
3. Brake pads:
A. Front MB OEM 008-420-20-20 (you can go aftermarket, but make sure friction of the aftermarket pads is GG, do not settle for anything less)
B. Rear MB OEM 007-420-86-20 (you can go aftermarket, but make sure friction of the aftermarket pads is GG or GF, try not get FF)
Everything above is a straight bolt on with NO other parts need/required. Depending on you car's age, consider changing flexible brake lines (they are under $100 for the full set of four) front p/n 166-420-03-48 (2) and rear p/n 166-420-04-48 (2).
When done, bleed, bleed and yet again bleed your new brake calipers following correct procedure (yes pumping brake pedal because hydraulic system was opened when new calipers were installed) until no bubbles and brake pedal is firm.
I know this info was asked for before by a few posters.
Did you DIY? If so, where did you get the various torque settings from related to various hardware for the caliper hanger, caliper etc etc etc. cheers. Did you loctite the torx bolts for the caliper hanger blah blah blah?
Also, just confirming that you did NOT have to change your front carrier brackets (only the rears)? Cheers.
Brembo calipers have NO carrier brackets (the design is totally different from "floating" calipers).
Information regarding all parts required with p/ns I provided above is detailed and complete.
Hi @threeMBs I have finally pull the trigger in ordering the brake kit at MBpartsource as they have the cheapest pricing for the system and order the Brembo rotor at eeuroparts.com, I will keep the updates here thanks once again for providing the guide.. total dollar spend close to 3k for parts including the brake pads ,rotors, caliper, back bracket, bolts etc.. and labor is $500 for install all 4 of them
Edit: Keep in mind that if your stock GLE350 wheels are 20", then you will need 15-20mm spacers upfront, if they're 19" - they likely won't fit upfront at all even with huge spacers of 30mm or so.

Reason: Spacers are required upfront.
Hi threeMBS.. Just a question here did you paint your rear caliper bracket to gray? I just received mine and it is nowhere close to your caliper bracket color..
and if yes can you share with me what is the spray paint you have used?

Yes I have, both the rear calipers (except the AMG plate of course) and the brackets.
Since I could not find the silver/gray color to match the fronts (it seems everyone paints calipers red), I used flat grey primer (many coats), then finished with several heavy coats of gloss clear coat:

Markrym, after all this time just looked at pictures of your car. Please, ignore above reference to stock wheels since it does not apply to your wheels. Yes with those wheels (exposing...well less than eye pleasing "base" brakes) upgrading to AMG brakes is a must. You will be pleased with results I am sure. Wheels and brakes will greatly complement each other.
What is the size including width of your wheels and the offset?

Just an update I was able to get all order from MB only thing missing are the rotors from eeuro.. ill keep posting upadates thanks once again threeMBs…
That's a very good deal. How do you like the upgrade?
Let me share a little bit of story in this project, I knew from the very beggining that I need to make two changes on this vehicle.. Wheels and Brakes.. I live in CA southside so there is really no need for me to get 4Matic however all the bells and whistle for add on to this vehicle are here, just to name a few, illuminated star, LED head lights, hot and cold cup holder, running boards led, etc.. now fast forward after replacing stock 19 inches wheels was able to focus and search in the internet for thread like this on brakes, however no luck at that point.. but when threeMBs posted this thread that made my day and everyday I keep on reading doing my search comparing part numbers for regular GLE350 to AMG43 and AMG63 just to make sure I will not miss anything.. biggest concern for me are the mount for calipers would it be different from a vehicle with strut, shox and springs vs airmaric etc. so upon calling the MB dealership where I purchased this at www.mbpartsource.com, i spoke to a gentleman and he told me it will fit however they do not want to be liable for the info, and i told them i wont take it againts them and by the way the items are non returnable so i gamble.. told myself if this will not work i will just sell it at ebay or something, now pull the trigger for install and as what threeMBs mentioned it is really a nice upgrade, you get that more stopping power and to be honest the way it drives now it feels more lighter than having the OEM rotors for some reason..
night and day difference on this plus bigger wheels and bigger brake kit is really an eye catcher or neck turner, lastly here in CA traffic is harsh so it was nice seeing people looking at your wheels and smiling at the same time..
