Sold mine dirt cheap just to get them off my hands and that included the calipers being painted to match the car, almost new Brembo rotors and Porterfield brake pads. The number was too low to mention, although my front OEM calipers were not the early Brembo's, they were the later Ate calipers (front and rear).
BTW - don't forget you need 17" or larger wheels for the SA setup. Most, but not all, 17"+ wheels fit. Early Monoblocks (from mid 1980's) and the 7.5" Evo wheels are two known exceptions.
Febi LCA's are ~$400/pair. OE LCA's are twice that. Plus pads, rotors, calipers, labor (if installed by a shop), and alignment... it adds up fasssssst! But you stop even faster.
Steve's part numbers all look correct! You can also get pads from Akebono and EBC, in addition to the OE Mercedes pads.
So for the brakes I am thinking two options SA or SLK55 6 piston 340/360mm rotors.
Visited my lovely dealership and here is what I found.
Pricing for those who might be interested in how much are those brand new.
Rotors SL55 R230 , two piece , 360mm
230-421-12-12 - $935/$841
So based on the prices I am thinking more about 6 piston calipers , look big and fancy , exactly what I want . The only problem is rotors
Ditto what Arnt posted above. Also, the calipers are different between 340mm and 360mm fronts. You MUST get matching calipers+rotors. Your list shows the same calipers but with two different rotor sizes... can't do that.
The Silver Arrow kit is the only kit I know of with factory parts that can be installed without major modifications (other than the lower control arm swap, and rear dust shield trimming). The aftermarket kits from StopTech and MovIt should also be bolt-on, but at an insane price.
You can get full Silver Arrow kits with used calipers for under $1k, or around $1200 including new rotors & pads. It's not worth buying new. Don't forget you MUST upgrade the rear brakes to match the front, especially if installing the 6- or 8-piston AMG fronts.
The 8-piston setup will not work without a lot of custom modification, and IIRC, also custom rotors ($$$$). Generally, a bad idea. Not to mention those rotors are some of the heaviest boat anchors MB ever produced. (!!) I've seen some 6-piston setups installed with OE 2-pc rotors but the mods are much more than I'm willing to do. I don't recommend any of those brakes for a 124/129 and I can't help with technical info, sorry. If you want/need bigger than Silver Arrow, buy StopTech or MovIt. The Silver Arrow setup is plenty adequate for any E500E up through about 450-500hp... the only time you'd need larger brakes is if you had more power than that, and I can count on one hand the number of 036's with over 450hp.
The Silver Arrow kit has been proven to work well with the stock master cylinder. I can't say the same for the 6- or 8-piston setups, except to pass along the feedback from the previous owner(s) of my '92 which had the 8-piston fronts installed with 4-piston rears... they reported the pedal feel was poor (excessive travel, I think). The PO of my car removed that funky setup and installed Silver Arrows, which worked GREAT.
If you have an unlimited budget and can experiment with custom AMG brakes that have not yet been proven on the 124, great, go for it... just don't be surprised if you end up having to re-do work and change calipers/rotors/MC's because you're not happy with the results. Then again, if you have an unlimited budget, just buy StopTech or MovIt kits which are properly engineered for our cars and don't require funky mods. If you are on a budget, I'd stick with what has been proven by dozens of people (not two or three) worldwide to work well. Not to mention they are a bargain.
Used Silver Arrow, all four with new rotors/pads, est $1200 total
StopTech, fronts only, est $2500 plus larger OE rears
MovIt, fronts or all four, starts at ~$3000 and goes up to ~$10k, I think, depending on how crazy you want to get
Keep in mind, the SA's front calipers are Brembo's, which are prolly better than AMG. The rear calipers are Ate (which make good brakes as well and have been providing OEM brakes for Mercedes for a long time - the "only downside", the rear Ate's do not look as stylish as the front Brembo's do and that's where the AMG kits wins, do I do understand your pursue for the AMG's), but the one that counts for your stopping power are the front calipers. Otherwise, I bet StopTech would have a rear kit as well.
I believe most of the AMG calipers are also made by Brembo... at least some of them are, not sure if all are though.
Fronts provide the majority of stopping power which is why they are larger than the rears. StopTech designed their front kit to work well with stock rears, although I think you could use the 300mm Ate rears with StopTech without issues if desired. I don't think I'd bump up to the 330mm rears with StopTech fronts without consulting their technical department first. I think StopTech didn't do a rear kit more for lack of demand, but I'm not certain. I remember the guy who worked with StopTech to develop the kit (500Ecstasy forum member "Guido", IIRC?) years ago on his 500E.
You guys make me more excited to get brakes update.Rotors for the SilverArrow brakes are $338 (non-drilled) for all four Zimmermans delivered from AHAZ, or $432 for cross-drilled. Pads are $110 for front+rear for Akebonos from Amazon. Figure $450 total for non-drilled rotors and new pads. You'll pay a bit more for drilled, or if you want OE MB rotors/pads instead of Zimmerman/Akebono.
The main cost variable is the calipers... I sell all four rebuilts for ~$1k when I can get them, and used ones for less. Let's say $750 delivered for a set of good used calipers (cleaned up & ready to bolt on), plus the $450 outlined above, and you're at $1200 total plus installation. I saw that kit you mentioned at $1199 for fronts only (USED fronts!), I think they are a bit, uh, optimistic. I must say they did a nice job with the paint job and photos.
Used calipers are usually fine from a functional standpoint, but the cosmetics can vary widely, and it's often a PITA to properly clean them up & paint them, plus they should have the pistons cycled in & out to verify smooth movement, which is also a hassle.

Roma, it's the opposite. The rears are almost a bolt-on other than cutting the dust shield. The fronts are a nightmare to install. For starters you need to cut the steering knuckle, and fabricate custom hydraulic lines.
Basically you used compressed air to push the pistons out against a wood/metal block the thickness of the rotor, to prevent the pistons from popping out of the caliper body. Then press them back in (carefully!) with pliers. Repeat several times. Make sure all four pistons will come out with air pressure. Don't let any piston pop out of the housing or you'll be in trouble...Care to enlighten me on this process? I was wondering how to do this before buying everything needed to switch over to the Silver Arrows I bought off of Benzworld. Hate to spend all that time and money and find out the callers need a rebuild because the pistons are frozen.....
...any chance that would work?
The only difference between the 6-piston AMGs for 360mm versus 340mm is the height on the mounting bracket. Seconhand calipers for 360mm is hard to find as a needle in the haystack, so I bought calipers for 340mm and planned to replace the mounting brackets. But the mounting brackets are not sold separately, so I contacted Brembo to do the replacement, but they don't take on such jobs. So I'll make 10mm sleeves and use longer bolts. I have copies of the original Brembo assembly drawings showing materials, dimensions and tolerences. The calipers are also specific for left and right due to differential piston bore in the rotational direction.
For the rear 4-piston AMGs it depends on which type you are using. Those shown in my previous post is the newer type having a style more inline with the fronts, so I chose them. These doesn't fit at all, but the interface is ideal to insert a simple mounting bracket. I hope to have those brackets water cut. The previous 4-piston AMGs shown in this post fits directly on the car, and they are not so expensive either. That blue set is for sale in case someone is interested.
Here is a thread with some information about AMG BBK (big brake kit):
http://www.500eboard.com/forums/showthread.php?1037-6-piston-AMG-calipers-and-360x32mm-discs
I have not investigated so much on the brake pump and booster yet. I expect a longer pedal travel due to increased piston chamber volume, but I want to try it as is first.
You need a compressor with a tank that has a healthy reserve. I've never experimented to find out the minimum pressure but my setup feeds ~100psi. Oh, I forgot to mention, make sure you leave the pads installed when testing! And insert something approx 32mm thick to simulate the rotor. That prevents the pistons from overextending.Thanks Dave! Any idea how much air pressure is needed? I don't have an air compressor but I have an electric air pump that can inflate car tires
You may not need a custom bracket, but you still have a lot of custom modifications required, including cutting the steering arm, and custom hoses, etc. Nothing about this is a bolt-on.
Uh, those would be the Silver Arrow brakes.
There are a few different rears available. You need to get the correct rears. I am not aware of modifications required for the rear if you get the correct stuff. (Sorry, I can't help with part numbers or models/years for donors.)
For the rears, if you needed longer hoses (I don't think so, but just in case) WRXtra can make hoses longer than stock if required. For the 6-piston fronts, IIRC you need to cut things and use a banjo fitting. You'll need to search other forums and see what other people had to do. I've seen photos and I was NOT willing to do the mods required. Simply not worth it for what ends up being an appearance package. What I saw was on the 6-piston calipers, you have to cut / mill the fluid inlet on the caliper, which is something you can't un-do.
It has to be banjo bolt on one end and regular fit on the other . Is there brake hose like that for sale ? Cuz I do not know how to make that kind of hose plus do not want to monkey around with brakes 
Here's a link... they don't list part numbers, but it's the C-,D,E,S-,T- hoses Front and Rear:
I do think I should save in this case basically because bake calipers go for the rest of the car life so unlikely I ll have a chance to remove them again unless I want to install 6 pot calipers. So that is why I want to do a proper job once and forever .
I think I ll take them to shop to repaint them cuz I m really bad at painting
Hello Guest !
We wanted to let you know about a new resource that is now available to all 500Eboard members. This is a comprehensive database of all US-market (and soon to include Canadian-market) 500E and E500 models delivered for the 1992 through 1994 model years.
Data for this resource has been compiled continuously since mid-2003, and much of this information is seeing the light of day for the very first time ever. This new resource will allow you to utilize 500Eboard research and resources to track specific cars, their sale history, documented modifications, and other information that has surfaced over the years.
We are also providing analytics about the cars' production. This means that if you are curious as to how many "Signal Red" cars were produced for the US market with a black interior, specifically in Model Year 1993, you can now easily find this information. You can also find aggregated information -- for example, how many "Black Pearl" cars were imported into the US over the three-year span.
You can always find and enjoy this resource by clicking here (bookmark the site for easy reference!), or by going to the “500Eboard Registry and VIN Database” sub-forum below. You can also find a VIN Database button at the top of your screen, for easy access.
We hope you enjoy this resource. A LOT of blood, sweat and tears over nearly 23 years have gone into its creation.
Cheers,
500Eboard Management
