Hello guys,

So I'm going to replace my rear pads and rotors cause it's time.

I've established through research that Zimmerman rotos and Akebono pads are the best options, although if you have other suggestions let me know.

I'd like to find the part numbers as I'm hearing conflicting numbers corresponding to their models, some say one thing others say another, so help there would be appreciated. Thanks!

I have that exact combo all around, highly recommend zimmerman rotors and Akebono pads, the rear disks are 300mm on all of them, the front changes from 11.6 inch on the base to 12.6 on the sport and I think the c350 sport has even bigger rotors. Also the pads are different on the 11.6 and 12.6 rotors, do you have the sport pack or just regular brakes ?

I will also be doing that exact combo F and R this summer. Itwargssf, where did you find your parts in Canada? I can find the rotors in the USA but not up here.

I am also looking at Bosch quietcast rotors.

W204Motorsports

I have a local german parts store ( Bernnie Auto) but what ever they cant get or is too expensive from them, I get from either ebay or http://www.pelicanparts.com/catalog/...17_catalog.htm

these 2 sites are where most w204 parts are found.


Also Rockauto has some parts, very few but like my Akebono pads I got from there.


Parts are available for these cars but very scattered, russia has a lot of oem parts that the west cant get.

Why are you guys switching to non oem brakes/rotors? Just curious

Brake pad thickness at replacement time...........is it: 4mm/3mm? Does a code pop up on the dash?


TIA

you can try these two sites they sell the brake kits for both front and rear and include what you would need for the job. And fcp euro site has a very good video on how to do the brake job

On your dash you will see a message that states your pads need to be replaced. There is a sensor on the right front and rear pads that alert you to the pad wear. My pads are at 3mm and I will be changing them this Sunday. You could wait until the sensor goes off, from what I have read on this site the wear front to rear depends on the type of driving and if you have a staggered wheel set-up.

Just204

Agreed, I'm curious as well.. is it just cost? And what's the best brand for these cars(like rotors not warping or cracking).

ezshift5

Thanks, hombre.........

I do have staggered wheels - 32,350 miles (and a lot a brake dust from those OEM pads).

......reckon I'd buy start saving my USNR drill pay for pad replacement before too long.

appreciate your response, amigo

The Zimmerman rotors are coated with zinc so they don't rust like the oems on your car. The theory is that the added rust ads weight to each wheel. Plus if you look at your rotors they are vented which helps cool the rotors. The vents get clogged with rust and the rotors don't get as cool. You would be surprised at how much rust falls out of those rotors when you take them off.

The Akebono pads are ceramic anddon't dust as much as the oem pad and they are suppose to be better for your rotor.

I have the ziimerman and akebonon pads on the front of my car and after 45Kmiles there is still a lot of material left.And the rotors look like new. I will be putting a new set of rotors and pads on this weekend. The rears need to be done after 88k miles.

Hope this helps

Rotors getting some rust is normal in the vents, won't add weight. Rotors are hydroscopic so they all absorb water, except ceramic rotors. Pretty sure OEM pads are semi-metallic most likely so they wear faster but normally you can go through two sets of pads before replacing rotors. Ceramic pads are more wear resistant and harsh on rotors and chew them up, but because of that they last longer but the rotors will be shot by the time to replace pads if even by then, so next time it will be pads and rotors instead of just pads. But they hold up a lot better with aggressive braking and resist brake fade better. It's a trade off. I think my OEM rotors are zinc coated as well, a lot of OEM manufacturers are doing that now. Maybe Zimmerman rotors and OEM pads would be a good combo if they are better?

Adi-Benz

As the other user said, the zinc covered rotors and less brake dust from pads. Also in the past ceramic has been great for our jeeps; I assume no different here, other than the fact that supposedly stopping distance is "about the same" instead of "better."

A light may come on when its time. If they're warped or something the sooner the better.

Does anyone have specific numbers for 2010 c300 4matic sport? EUR1302 or 1300? Or something?

Also my front pads and rotors were new when I got the car. I've done 6k miles and they look ugly cause of brake dust (yes I try to clean) they drive fine so I may just do rears, depending on price.

Ceramic brakes do not work well in cooler/cold temperatures. I had them on a previous vehicle in an effort to cut down on brake dust but the braking performance was notably poorer in the -10 to -25'C range.

They may work for you guys as most of you are in the US but here in Canada, no bueyno.

Good to know about the zinc covered rotors though. I don't think that's enough to push me away from OEM but good to know. Danke!

Adi-Benz

Not necessarily. Not sure what was the case with your experience, but even so, after 1 or 2 light brake stops they will warm up enough regardless of outside temperature.

Also ceramic don't chew up rotors like someone above said. They are capable of breaking harder (duh) and maintaining rotor rigidity, whereas if you "broke" the same with semi-metal or whatever it would do more damage.

Then again we all have different experiences so not here to call out anyone negatively that has a different experience from mine.

superangrypenguin

Actually, now that you bring it up, yeah, I do remember that. The first one or two light brake stops were the worst with ceramic but then it did get better as you said! Obviously ceramic is less "hard" than semi metal so I would agree with you 100% that ceramic brakes are easier than rotors.

I remember doing 1xx km/hr for an extended period of time (late night driving) (xx because I don't want to incriminate myself...) and then having to slam on the brakes. That was not a fun experience (it was probably -20'C in the winter).

Ever since then I've stuck to OEM. I understand that it's more of a pain (brake dust) but b/c I had a "poo has come out" moment I've stayed away from ceramic, LOL

PS - I do realize my situation was pretty unique. It was an emergency maneuver which kicked off the safety system that detects that it's an emergency brake and thus applies full brake. The performance that was given to me by ceramic brake pads was not up to what I was hoping for.

Then again we all have different driving styles and drive in different climates so what may work for you may work well indeed! Just thought I'd point this out.

Just204

That is true, everyone has a different experience. My car I sold to get the c300 was significantly modified. I custom modified a different cars larger brake system to fit it and went with ceramics. I drove that car hard every day and tracked it. I went through the original pads and warped the original rotors in 13k. thats why I did a brake swap with ceramic pads as soon as I could. I stopped on par or even better then my Mercedes and put another 30k+ on it until the rotors showed they were starting to warp from driving, the rotors were thinner which makes it easier to warp them but the pads had a ton of material left(75% good). I went with ceramics for the performance even though after a lot a research I read the affect of using these pads on rotors which is why i said what I did. I mean Ceramics are the way to go if your a hard driver no questions and I may do it anyway even if it costs more but I am happy with stock performance right now until when I decide to push this car as well lol...normal driving on quality rotors and ceramics should last a long time for the normal person, and there are "different" ceramic versions/blends depending on what you want.

I have Meyle HD rotors and Akebono pads on my rears and they're pretty good but when I replaced my fronts I went with Textar ePad ceramic pads because I prefer the OEM style braking dynamics. The ePads do produce less dust than OEM pads with similar behaviour to the OEM pads but they produce more dust than the Akebonos.

Also the part number for the rear Akebonos is EUR1341.

Adi-Benz

Thanks! Confirmed. Is it 1340 or 1342 for fronts? "for future reference"

Also does zimmerman make slotted/drilled rear pads? just for cosmetic sake - if not I don't mind.

---
Also totally understandable the experience you guys had. I'll give em a shot, even so I'll still have semi-metallic in the front for now. Possibly a good combo? Haha.

CGSColin

You mean rear rotors? If so I don't think so.

The front Akebono part number for the US spec C300 is EUR1340.

EUR1342 is for the C350 and the Canadian spec C300 (which has the C350 rotors and pads).

Adi-Benz

Where can I find the zimmerman rear rotors? Part #? Also do they have drilled rotors to match front?

PelicanParts.com

We have front/rear Zimmerman vented/coated rotors here: http://www.pelicanparts.com/catalog/..._pg3.htm#item8. Unfortunately, it doesn't look like they have the drilled rotors for the rears. Let me know if you have any other questions.

Akebono pads are here as well if needed: http://www.pelicanparts.com/catalog/..._pg1.htm#item0
DIY here if needed: http://www.pelicanparts.com/techarti...204.htm#brakes

Adi-Benz

Thanks!

Also thanks for your diy's, they are very helpful!

Adi-Benz

Do I have 300x10mm rear? I thought mine were vented, but those arent for sport pack?

Regarding the rotors in the rear.

CGSColin

Rear rotors should be single piece non-vented. They're not particularly beefy.
