Recently bought s560 I’m looking to upgrade to AMG calipers but I’m not sure if these parts are compatible. I have recently found these calipers to see if they would fit. I would also have to measure my rotors to check fitment but need some community help thanks. I read in different post you would need 390x36 bracket depending on rotors

AMG Calipers? Do you mean the ones used with two-piece rotors on the S63/65? I looked into this a while back, and an adapter bracket was needed to mount these calipers to the standardr S-class spindle ... https://www.killerbrakes.com/product...s65-420mm-new/

sclass(w222)

yeah I was looking at that website to I’m having trouble figuring out which bracket to get because i guess the AMG rotors are 390x36 and I’m assuming I don’t have those rotors. Not sure if this picture helps but these I have on right now. These might be 420mm that you mentioned?
The gentlemen on killerbrakes told me if you have the 390mm rotor they could fit on the amg caliper. The standard s class uses 420mm? I saw its out of stock but is it possible I could use 390mm? but that means I would have to replace my front rotors

Tom in Austin

A big assumption is that the AMG cars use the same hubs and spindles as the S560. If they do, then all you'd need is a suitable caliper adapter and the appropriate size brake rotor.

I think the standard front rotor is actually 370 x 36 mm and the AMG rotor is 390 x 36 mm.

BTW, I misspoke in my previous post, the AMG rotor is not two-piece but you can get a two-piece aftermarket rotor with aluminum hats ... https://www.ebay.com/itm/36350384209...AAAOSwVsZhFZSk. These with the AMG calipers and pads like EBC Redstuff would be a sweet upgrade.

Ah okay makes sense no worries I appreciate the insight very much I think I’m get those 390 brackets then I’ll just have to get new rotors. I guess brackets hard to find. As for the rear I don’t think I need anything? AMG rear are 360x26 correct me if I’m wrong I’m very new to mb or do those need to be changed out as well

crconsulting

AMG calipers for W222 are same as R231. I’ve done this upgrade on a couple of cars. It’s a straight “bolt on”.
The ones your looking for are Brembo casting #
20.B282.05
20.B282.06

The brackets are NOT available separately. So make sure if you buy them used, they come WITH the brackets. Sometimes you can get lucky and find the brackets at wreckers or on eBay separately.
Some of the Maybach cars also use the same 6 piston brake calipers, but are marked Mercedes Benz instead of AMG.
(see pic)
The AMG cars share the same master cylinder as the non AMG cars. Proportioning is not an issue in conversation. Spindle mounting location is identical between AMG cars and Non-AMG.

You will need 390mm front rotors and 360mm Rears. If your car is RWD, I usually go with the Brembo 2pc rotors as they are considerably less than the Mercedes Rotors (especially the rears) and as a consumable make much more sense as these cars tend to wear rear rotors at a 2 to 1 ratio with the fronts. Mostly due to traction control and Distronic. Fronts, 390x36mm Brembo Part Number 09931333 (09.9313.33). Rears 360mm x 26mm vented Brembo PN# 09B87911 (09.B879.11) compare pricing to MB Part Number rears) 222 423 20 12 / 2224232012

AWD cars will need different 390mm F. and 360mm R. rotors than the above!

There are two different style caliper brackets for the Brembo 6 piston calipers.. There is also a slight difference in brake line mounting between the two.
The mounting brackets are different too. Visually, they have more of a radius at the mounting location. W212 brackets are flatter.

The ones you have linked above are for (W212) C63, E63 etc….

Good Luck!

Wow, there you go, everything you need in one post!

sclass(w222)

I see now, so I can’t use the w212 caliper or could I use the 390mm bracket for them? I spoke to someone on killerbrakes they showed me the w212 calipers on 390 brackets pics are below

crconsulting

No, to do it properly, you need the Brackets SPECIFIC to your correct calipers (Brembo bracket casting # 20.9747.72) The brake line mounting configuration is also slightly different between 212 and 222/231 calipers

(edit) looking over the pictures you just uploaded more carefully, the brake lines mounting location is still slightly different from the proper W222 calipers. They may “work”, but if you’re going through all this trouble, you might as well get the correct calipers.

I wouldn’t be paying more than $700 for a set of used ones. You need the rear calipers too. 😕


here’s a full set F&R

here’s a pair of Maybach calipers:

Good Luck



look at the proper location for brake lines on the R231/222 calipers below vs the red ones in your picture. (Same as the 2nd silver one below)

W222/R231 Brake line mounting location.


W212 brake line mounting location further outboard. Caliper appears thicker too

sclass(w222)

yeah I see it, I’ll just keep looking around for a pair. I have the rear 360x26 calipers. I have the w212 front calipers I’ll probably just have to sell the front ones to order the correct one. I don’t want to risk damaging anything with e63 front brakes on a more heavy car.

crconsulting

Is your car 4matic AWD? The rotors are different for those cars.
Have a look at that eBay link for the complete set of Maybach calipers. Those are the AWD rotors….

They take the same pads, but I think the thickness (or offset)of the calipers may be the issue. Either way it’s best to get the right ones.
If you have the rears, you’re half way there 👍

Good Luck

sclass(w222)

Mine is RWD thankfully it’s not to much of a hassle. It doesn’t have metallic rotors it’s got ceramic. Would I need to change out my rear rotors as well ?

crconsulting

Wait, Ceramic? Are you sure?
Thats a whole different front caliper (and rear) meant for a 405mm Front Rotor…..

As long as we have the experts here, how about the rears? Isn't 360 x 36mm the standard S560 rear rotor? Is the AMG rear caliper any different besides just the logo on the side?

crconsulting

As long as it uses the 360x26 rotor, you are correct. It is the same TRW manufactured, “AMG” labeled caliper and bracket. ( it will be marked as pictured below) As mentioned above, MB also used a Brembo front caliper labeled “Mercedes Benz” instead of AMG. I know it was an option (or standard) on S600’s, some Maybach and maybe other W222’s.

Tom in Austin

Only other variable I can think of with the rears might be piston size, otherwise they look nearly identical.

It's kinda funny to me that Mercedes did that clunky cast-iron TRW sliding caliper in back on an AMG. Coming from the Porsche world I was used to Brembos front and rear.

*** Correction: Just measured my rear rotors and they are 340 x 24, so not the same as AMG rears.

crconsulting

Those 360x36 rear TRW castings all use the same size piston. In a way, It’s actually good because the rears are the easiest to find.

Yeah I’m with you. Aesthetically it’s a better fit too.
I think the parking brake design was a deciding factor. So much so, that other manufacturers (like Audi) use the design too. It’s fairly end user friendly and eliminates the “brake shoes” for a parking brake. To be fair, I would also think most people would never flog their S (or SL) MB as hard as they’ve driven some of their Porsches.
That floating caliper/single piston design has been around since the 60’s and is fairly effective. In the end, it serves its purpose as a rear brake for a heavy luxury grand touring car that has quite a bit of front brake bias.

H.D. brakes"/"Sport package brakes" for non-AMG engined cars (U28 / 950 & 951)
They work pretty good, but the larger dia. rotors help with wear especially if you use the traction control a bit


Good Luck

Found these. I assume these would fit my S550? I’m doing the brake upgrade and I found the calipers off a C63S since they are the 390mm and 360mm cause I can’t find the adapters anywhere no one has them in stock
