Brake Rotor/Pad part #'s?




I'm a DIY'r and have changed rotors/pads several times on my other cars. This one has a shimmy in it from the rotors and figured I'd just replace the rotors and pads all around.....but....
I can't seem to figure out which part numbers to look for? I usually shop at parts.com for my OEM's, but looking at their graphs and charts, I don't see the same kind as mine and quite frankly not sure if I am looking at the right parts. Can anyone help me out? I doubt mine are anything out of the norm from the others - front rotors are drilled, rear are solid. Pads appear to have about 40% of life left, but figured I'd just swap them out too during the process.
My VIN# is WDDHF8JB7EA988157 It's a 2014 350 sedan w/ 18" wheels and sport appearance option.
Many thanks!
I suspect I'll be on here quite a bit as I learn about taking care of this beautiful machine! I also have a 2015 VW GTI Autobahn (4-door / white) that I adore. This MB is to help spread the mileage out between the two cars. I typically rack up 20,000 miles a year commuting, and hoping to slow that way down so I can stop buying new cars every 5 years or so. Both of these vehicles make me very happy and scratch every itch I get!




My thought is that they'd tell me the rotors are bad, and then see if I wanted to pay to have them replaced. Given the easy of the job, I'd rather save the money and do them myself.




Now, a couple of other minor issues I've found will definitely be taken care of with the CPO, one being my driver's seat bottom that appear to have been crushed down to the point of feeling the frame on my butt! And the rear deck spoiler is loose on one of the corners (likely a car wash mishap). Other than that, the car is in perfect condition!
I suspect the previous owner (lease) spent a lot of time in DC traffic and stood on the brakes a lot in stop/go traffic. I avoid much of that mess with my own commute that is 25 miles each way with cruise control for 95% of it 95% of the time. I just need to figure out which rotors to get via the proper part numbers. Looks to be a sea of different part numbers out there for brake components.
PS: Where in Chicago are you? I lived in Glen Ellyn for 3 years prior to coming to DC nearly 6 years ago. I'm the only guy on the block with an electric start snowblower, and bet you can guess where I bought! Keeps me in good graces with the HOA!

I bought parts from ebay(Rhode Island MB Dealer) and FcpEURO - Which had a crazy deal on Zimmeran rotors at $63 each.
here is the list.
Front Brake Pads - 0074205820
http://www.ebay.com/itm/MERCEDES-OEM...72.m2749.l2649
Rear Brake Pads -- 0074206820
http://www.ebay.com/itm/MERCEDES-OEM...72.m2749.l2649
Rear Brake Rotors -- 000423091207
http://www.ebay.com/itm/000423091207...72.m2749.l2649
Front Brake Rotors -- 000421301207
https://www.fcpeuro.com/products/mer...-e350-40433036
I paid $103 for both rear disks , $72 & $76 for Brake Pads, and Zimmerman Front Rotors $126. Total: $377 ( All OEM or OEM Manufactuer)
I spent probably 2hrs researching different catalogs because many of these numbers are interchangeable, but I guarantee these will work as I have done this job last week and everything fit and works perfect.

I went brake shopping today in general. Amazing to me that I can buy all new pads, rotors, and ancillary parts, all genuine oem for 3 cars, for way less than paying a dealership to do just one car. Especially when there is usually more bolts in just taking off the wheel than there is to replace pads and rotors in general! A MB, VW, and Toyota for $1,250 +/- a burrito! I like to do my own because I like to make sure the little things get done in the process, like making sure the floating pins for the caliper are cleaned up and properly greased. The hub cleaned with some steel wool, antiseize lightly used, and ESPECIALLY the wheels are put back on correct with the right tightening pattern at the right torque. I strongly suspect that these rotors have warped this quickly because of improper torquing down on the wheel studs. And I think the front right rotor is slightly dragging, likely due sticky guide pin(s).
Plus, since the wheel is off, I like to take the opportunity to clean and wax up the inside of the rim itself. Really makes a difference in appearance and with helping to prevent brake dust and the like from sticking to the wheel.
Again, thanks for the great advice and help!!




Front Pads: 007-420-58-20 ($63.72) One for the front entirely (not one for each wheel)
Rear Pads: 007-420-68-20 ($60.18) One for the rear entirely (not one for each wheel)
Front Rotors: 000-421-30-12-07 ($92.04 each)
Rear Rotors: 000-423-09-12-07 ($43.07 each)
I shop at parts.com for my OEM parts (not endorsing, just the only site I've really known about for the past few years). You've got to give them you vin# so they can verify that you're ordering the right parts, otherwise no return policy happens.
Hopefully this will help others who go hunting for this same question! It's a sea of different part numbers out there and confusing as can be to figure out. Thanks again for putting me on the right path to figure this out!!
