Does anyone know if the '05 SLK350 front brakes work on a w203? I've looked everywhere and can't seem to find the answer. TIA!

It'll work for sure. What wheels are you running? Just make sure your wheels will clear the caliper

Thanks for the reply Karo. I'm running SSR GT3 18's. Not sure what the ofsset is though. From what I understand, the SLK has brembo brakes like the C32 & C55 as well but use smaller discs? Something like 330x28mm front vs 345x30mm front !?!? I just got an entire SLK brake set off ebay for $120.

W203E35

Same disks as the C55 as well.

My car (C350) also uses the 4 piston brakes (C32/C55) and I buy the C55 rotors (recently changed). One way to double check is go to rmeuropean.com and search C55 Brake Disc and SLK350 and it'll come up with same part number 203-421-09-12

Disks are 116.00 each out the door.

Edit:
Great deal. When you do the calipers you'll need to do a brake fluid flush as well with a set of new rotors you are good to go. You'll feel a difference for sure.

NElz

Hmmm.. I'm getting 203-421-13-12 from rmeuropean.com for the SLK350 '05 ?!?!

WaveyKat

i have SLK55 REAR Brakes and CLK63 Front :-) you just need to Trim the Dust Plate for the Caliper to fit..

W203E35

Can you take a pic of the calipers? That part number is indeed for an SLK350 and a CLK350 as well. I remember a member was selling CLK350 Sport brakes and they were the 2 piston rather than the 4 piston.

W203E35

If you do have the 2 piston then your original comment about size is correct but that's not the C32/C55 Caliper. If you do have the 4 piston then your original comment about size is incorrect and you really do have the C32/C55 Caliper.

Post pics and we'll tell you right off the bat

ROLLNNN

This is the upgrade i want to do. Do you have any pics??

Thanks,

on rmeuropean.com, I'm still getting 203-421-13-12 for the 2005 SLK350 and 203-421-09-12 for the 2005 C55amg

W203E35

let me hit up EPC and i'll get back to you. Give me 10 min. Let me get to the bottom of this.

oel

not exactly sure, but those "look" just like the 04.5 c230 SS calipers.
I remember reading that the ones with the 4 bolts on the front are 4 pistons.
I would guess they will fit your car.

Pretty good deal you got on those too

W203E35

I don't get it all those part number contradict themselves.

Check it out on RMEuropean we confirm that the C350 and C55 Rotors match up right.
On EPC the dealer part lookup I found that the C350 and SLK350 the one you have match up as well.

C350


SLK350


If it's confirmed that me and you have the same calipers and RMEuropean confirms that me and a C55 use same rotors I don't understand what's going on?

I honestly don't get it.

Been thru this myself with part #'s and different sized calipers/rotors... See this thread:

https://mbworld.org/forums/c-class-w...t-coin-ed.html

The numbers on the outside of the calipers mean nothing. You want to look at the #'s cast on the arms of the calipers. 330 will take the smaller rotors and 345 will take the larger rotors.

BTW, I still have one of each of these guys for sale, i.e. one w/330mm length arms and one with 345mm length arms, if anyone's interested (thanks to that a$$hat coin...).

W203E35

Ahhhhh How did I forget about this thread. mtnman to the rescue. You are correct these are not the C55 calipers.

Anyway buddy here is how to change the caliper.

NElz

Ok, thanks everyone for clearing that up. Some I do need the 330 size rotors then. (I still have to go across the border to pick up the brakes so I can't check the numbers on the arms yet).

Hey is that granville island in your sig. pic? Yeah, it was a steal at that price. I just jumped on it the moment I saw it. They are in kinda rough shape but I figured a few hours refinishing and painting em should make them look new again.

Sorry to hear what happenned to you mtnman. Hope my brakes turn out okay. Did you ever get new brakes then?

Thanks for the attachment Karo!

quadoptix

nope not c32/55 calipers they look like my stock calipers on my c class. wow those calipers look to be in much better shape too lol

NElz

yeah, they do look horrible. Anyone have suggestions on refinishing process - technique, paint?

WaveyKat

as requested :-) Enjoy

quadoptix

nah meant yours look better than mine lol. when i get my car back ill take a pic. never ever use that wheel cleaner spray stuff. it literally eats the finish off calipers right off. the benz was the first time ive ever used any kind of wheel cleaner spray as i know its generally abrasive. all my other cars with custom wheels ive always used soap and water, i was just lazy that one time and now my calipers look like crap lol. as far as painting goes, just use high temp spray paint. im probrably going to paint mines flat black just to keep it simple. im not much into painting stock calipers but they do have DIY paint kits for calipers or if you want to be lazy just use high temp paints and it should be fine. mask off the fender of course to prevent any overspray and make sure you dont get paint into the actual pistons as that can cause seizing.

W203E35

^^ that's what I did to mine. They had caliper spray paint but not the color I wanted so I bought engine paint. It did the job

NElz

So I don't need new dust plates for the larger rotors?

LOL. Thanks for the info. I don't have the calipers on the car yet so painting them should be much less work!

Anyone know if it's worth it to change out my rear brakes for the SLK's? I was planning to just do the fronts only and forget about the rears since I just got new pads on there.

quadoptix

you should be fine w/o the rears.

WaveyKat

NO you dont need a new dust plate... once you are doing the installation you will see where needs to be cut in order for the Caliper to fit.. then all you have to do is push the dust plate away from rubbing on the LARGER Rotors..
