Pix?

I will try to get some pictures up when I get home latter tonight. Here is a car on Ebay with the exact same rear calipers.

what size rotors are needed? direct bolt on for a slk32/srt-6?

Viper98912

Most likely not a direct bolt on, and the piston bores on that caliper are wayyy too large for the stock MC and overall brake bias (larger than the E/CLS/SL bores). Most interesting caliper though as it matches the stock C32/C55 front brembo caliper. What are the reasons you couldn't put it on your SRT6? Post some more pix when you get a chance please

The pistons are very small and will work fine with the stock master cylinder. They use a 330mm rotor. I was planning on using them on my car and still may. The are not a direct bolt on as they use a larger bolt to hold them on. If nobody wants them I will use them. I have SLK55 rear rotors that i will use with them or try to find SLK55 rear calipers. I like these calipers because they match the Brembo four piston front calipers.

how would you deal with the larger bolts lantana? im interested

The 2006 S65/CL65 using these calipers have 32/30mm bores, which is no where near the piston area of the stock 42mm single bore or 28/26 mm bores on the CLK/SLK setup. E/CLS/SL uses 30/28mm bores. Original rotor used on these is 348 x 26mm that is 7mm taller than the stock 300 x 22mm rotor. I've been trying to find these calipers to take a look at them and also to see if Brembo made smaller bore versions of these calipers but I've had no luck. I think it would be cool if you could retrofit them to work with the stock setup to match the front 4-piston calipers.

I will measure the surface area and compare to my stock pistons. I did try to do a quick mock up and may do this again. It apears that these will not use a 348mm rotor on my car. The mounting ears aren't long enough. I am guessing that the mounting points on a S65 are further from center line than on a C/SLK/CLK/Crossfire. the mounting spacing of these calipers is that same as my car. If I was to use these, I would probably make a bracket from 1/4 inch steel that clocks the calipers slightly up. It wouldn't be that hard to do and they could be made to fit the SLK55 rotors. If I do this it would be a nice set up but not very repeatable since these calipers are very rare.

If you could use an SLK 330 rotor, then you would need to do nothing except bolt them on. If the holes are too large on the caliper, you could buy some precision collars with (12mm OD and 10mm ID is what I'm guessing you have) to take up the slack in the holes.

Where did you find these calipers anyway? They are definitely very hard to find, but should've come stock (or at least, a smaller variation of them) with the 4 pot fronts. Sorry for turning your FS thread into a brake swap thread....

slk330mm rotors are front only 300 mm rears with the ebrake setup

Viper98912

R171 SLK AMG rotors came in 340/360/345 variations for the front and 330/300 variations for the rear

320 dreamer

gotcha. thinking r170 like lantanas xfire

Post the piston seal numbers and I can tell you exactly what size pistons these have.

Here are some pictures.

I just measured the pistons with some calipers and they measure 1.0" and 1.1" this is real close but may not be a perfect measurement as the measureing caliper was a bit hard to get in there. If you total up the surface area and compare to single piston calipers you will find they are very close. Even when conveting from single piston front floater calipers to C32 you have a similar small increase in surface area. As long as you are keeing the surface area real close to stock you will not have a master cylinder or braking balance issue. I have designed and sold big brake kits to Mini Cooper racers in the past. I am real tempted to keep these because an adapter braket could be made to fit them to just about anything. I bought these off of Ebay a year ago and they just sat around while I got my V8 conversion done. I am currently running stock non SRT rear brakes with SRT/C32 front rotors with CL/S 500 front calipers. I am currently looking for C32/C/CLK500 front calipers. I have a set of C32 front rotors. I thought if I go 330mm in the rear I should go from 330 front to 345 to keep it looking right. I was thinking of selling thes and finding SLK55/C63 rear calipers but they seem to be just as rare.

Viper98912

I wonder if they really are 26/28 on the backside of the piston or they just neck down on the outside giving the impression of 26/28. Im interested in what youve got going on and im tempted to buy them myself lol. Already spent a bunch of money on another conversion though.... Im really curious to see how everything lines up on the 203 spindle. Let me borrow them :P

LantanaML320

I know I am really close on the piston size. the sizes you gave above are for a 2006 that uses a different caliper. These are from an earlier S65 / CL65.

320 dreamer

guess im out guys. i was given a fantastic price on a 8/4 setup and im gonna try to make that work.

Viper98912

Cool beans 320. Lantana lets continue our convo in PM. To all the vultures, consider these sold for now :P

Sheesh! Are my post invisible here? Stop guessing, post the seal numbers... don't even need the entire number just the last two digits in the series 20.4872.XX

LantanaML320

I have measured the pistons again very carefully. They taper a bit at the top but I was able to press the tips of my calipers (measuring tool) down past the dust seals just a bit and they are 26 and 28mm. I cannot read the part number on the dust seals even with my reading glasses on. My best guess is the last two numbers are 42 and the other is 41 or 47

Viper98912

So watcha think havoc? I found this online http://www.motorquality.it/easysite1...%202010-12.pdf which states diameter of 30mm and 32mm with those part numbers. I don't know if that's for their piston diameters though or if it's for their overall diameter. Lantana what's the overall outside diameter of your seals?

havoc01

The dust boot seals don't lie! As the listing shows, those numbers correspond to certain size pistons and I've actually checked this against known piston sizes in certain OEM Brembo calipers... Most late model OEM 4 pot rear Brembos utilize some combination of 32,30, or 28mm pistons. Porsche's use 30/28, AMGs (both the peanut shaped E55 and later E63 version) are 30/28, Cadillac CTS-Vs are 32/28.

I've seen 26mm pistons on Brembo's motorsport calipers(which don't utilize dust boots) but haven't come across anything smaller than 28mm on their OEM front or rear calipers; and maybe is just coincidence but you'll note from the listing those dust boot sizes don't go any smaller than 28mm either.

Viper98912

Well, except that the information I have says that the CLK/SLK rear 4 pots are 26 and 28, but I don't have any calipers or part numbers in front of me to confirm that.
