I have an opportunity to pick up a E55 rear brake setup for cheap. I just picked up a C32, and from what I have read on this board the SLK55 setup bolts right up. I tried a few parts sites on line to check myself, but non have the AMG option for me to confirm myself. Can anyone give me a yes/no answer on this?

No, the CLK/SLK calipers are different than the E/CLS/SL/S/CL calipers. The piston bores are larger on the larger cars and won't work nicely with your stock master cylinder.

I'm sure there is a larger master cylinder that I can upgrade to. I just need to know if the bolt pattern is the same?

My personal opinion is that it's more of a pain and higher cost to try to redo the braking system rather than just trying to find the right calipers in the first place....

I'm sure Steve will chime in when he sees this, but you could PM him. He's the resident SLK expert on this forum. His handle is 320_Dreamer.

well i do apreciate the flowers but im hardly the resident expert!! splinter makes me look like a newb with his knowledge!
i believe the slk55 and e55 calipers from the rear are the same. the issues you will most likely incur would be proper spacing of the caliper and rotor diameter. both can be over come but its trial and error. are the rear calipers you are looking at 2 piston or 4 piston? the rear rotors on a c32 are 300 mm same as the slk32. the difference is in the fronts which carry most of the load. 345mm for the c32 and you really dont want the same size in the rear as the front. if you are keeping the oem fronts i wouldnt change the rears to e55 calipers

ok did a little search and looks like the e55 are 4 piston rears. you would want the 6 piston fronts to keep the braking balnce. maybe grab them and stash them until you find a set for the front?

I was hoping someone would chime in! Yes, I plan on going 6 piston up front to counter the fours in the rear. I would feel better if someone with a 203/209 can confirm this setup.

320 dreamer - The question of a bigger master cylinder came up earlier. I have performed a couple of brake swaps on Hondas. They usually rely on the Prelude, and Integra for larger capacities master cylinders. Are Mercedes master cylinders universal in the fact, can E and C masters cylinders be used between the two; or are the bolt patterns and mount points in different spots?

320 dreamer

honestly the mount points would be the least of your issues. most on here stay within the limits if their respective factory m/c so as not to have to deal with abs/esp problems. remember the ecu has files for antilock electronic stability control body roll and so many other sensors that all work in conjuntion with the brakes. i dont believe its a simple mechanical swap. thats why moost stay within 2 pistons of the oem setup. ie: going from 2 piston rear 4 piston front to 4 rear 6 front. if you look at the e55 setup its a 4 rear 8 front setup. and finally remember cheaper isnt always better when it comes to slowing you down from 150+mph!!

I was told by a Mercedes tech that the SL55 rotors will fit on the rear of the C55, they are the same price but cross drilled and give better stopping power.
He also swapped up the calipers on the fronts.

I had SLK55 rotors on the rears of my C32, they fit no problem.
