convert E 350 sport sedan front brakes to E 550 4 piston fixed calipers
i have a 2016 E 350 Sport Sedan and the front brake make noise when slowing down from higher speeds also they got warped after some high speed spirited driving on the freeways so i had brought car in to Mercedes dealer and they agreed to change the rotors and pads. now it is back doining the same thing . my opinion is that the sliding 2 piston caliper with the drilled rotors donot work well . so is there anyone in the forum that has adapted the E550 Four Piston calipers and rotors on a E 350 sport Sedan front brakes is this feasible and without costing alot of money please let me know thanks

The 4 piston brakes on the E550 have been known to warp or cause brake pulsing as well. Actually, pulsing among the E550 crowd is reported more widely than the E350 based on manufactured units. I doubt they would bolt right up in any event.

W212 E350 fitted with oem E550 brake rotors, calipers, brembo pads & aftermarket A&N steel brake lines.
I was the Guinea Pig for V6 W212 owners, I just installed 2014-‘15 W212 E550 oem Big Brake Kit with 14.2” rotors on my 2014 E350 4Matic a few days ago. I used oem parts and everything from the E550 fits on the E350 just fine, except for the stock rubber brake hoses. You will find the E350’s brake lines are too short. Solution is go with stainless steel (Army&Navy) 18” brake lines with a 90 degree fitting where the lines attaches to the Brembo caliper. It’s a tight fit, but nothing will rub or touch if installed properly.

So this mod is pretty straightforward with the exception of the brake line couldn't I just get a OEM 550 brake line as well for the swap getting a set of aftermarket 550 rotors is easy are the mounting points for the calipers exact or was there slight modifications made to them to get them to fit

Sounds like OP has something wrong with his system. Maybe fix that before throwing parts that cost 10x as much at it, especially if it's under warranty.

Now that I have foresight I probably should’ve tried the experiment with calipers from a AWD E550! I actually used calipers from a RWD CLS550. Rotor disc should be sourced from a 2014-2015 W212 E550. It seems the brakes hoses exit the calipers at different points on RWD vs AWD cars. I still was able to make the calipers work by using custom stainless steel brake lines. But it’s quite possible things would’ve ran smoother if I would’ve used Calipers sourced from a AWD car. The rotors bolt on with zero issues. My AWD original equipment E350 brake hoses were too short.

Mercedes Benz made the 4matic E550 for 2 more years after the W212 was face-lifted. From 2014-2015, after 2015 model year Mercedes discontinued the E550 “sedan” and gave us the less power E400 sedan available in 2WD and 4WD. The Coupé and Cabriolet E550 remained for 2016.
