1994 W124 E320 Rear brake rotors question

I just got finished replacing the front rotors and pads on my '94 E320. When I removed the rear wheel, I found that those on the car were not of the ventilated type.

Mercedes has given me ventilated rears, based on my VIN number. It does not appear that these are interchangeable with the solid ones. Am I wrong? The ventilated rotors are much wider in cross section, so I assume the calipers would never fit around them.

Can anyone shed some light on this for me?

Thank you for any help!

Mark

I have the vague memory that only the 500E/E500 has ventilated rear rotors, but I'm not sure. My 95 E300D has solids.

I think the wagon may have different rotors than the sedan. The wagon rotors are more expensive, and may be ventilated.

VIN cutoff point

appears to be F323055 for vented rotors, after that they are solid again. My father's 95 wagon has a serial number lower than F323055 and the rear rotors are indeed vented. Mark

We have no indication yet whether this is a wagon or a sedan. The sedan never had vented rear rotors. Another good example of why you should be specific in describing your model.

Yup...another confusing post.
It is a 124.032 sedan, but I had to go to poster profile to find out for sure.........bummer

And I Assumed it was too, reading the original post....until he followed up with the Wagon Post curveball , which implies he just may have a 124.092.
[ which others also went for]
No problem... just use the Parts look-up on top of the page and that will tell you which is what............

Nice, Arthur. Imagine how much time you could have saved if you simply asked: "Is it a sedan?"

Maybe I should have gone to a Mercedes dealer and given them the VIN.

Oh, that's right. I did.

Did I ask them if the VIN was all they needed? YUP.

Did I ask if they also needed a serial number? Yawn...YUP.

And what did they say? NOPE!

And now, just to be clear...

1994 E320 W124 SEDAN, built in 2/94.

And by the way, I do believe there were vented rotors used on some of the W124 wagons. To wit:

Balo
Brake Disc/Brake Rotor; Rear Left/Right; Vented
For wagon models with vented rear rotor and chassis serial number ranging through F323055. -
Per ******** Arizona

In the end, the question was really quite simple. Can you interchange solid rotors with vented rotors on a 1994 E320. I seems moot whether it's a wagon or a sedan, as the answer must clearly be no, not without making other modifications. And if it weren't for the fact the the MB dealer assured me they would fit, I wouldn't even have asked.

But now it's late, and I'm tired. I'll just go back to the MB dealership and swap them out, while giving them a thorough toungue lashing.

Thanks for trying to help in your own way...

Mark

P.S. The new MB sourced front rotors with Jurid pads are fantastic. Probably Balo rotors, or maybe Zimmerman.

The answer is NO and I was ready to tell you the Quite Simple NO until your next post suggested you just may have a wagon ????.. which changes my answer ..it's that simple. So, I took the trouble to profile to get the correct info on your car as to not give you the wrong answer.
A wagon has vented disc [ depending on the VIN] and a Sedan does not , [regardless of the Vin]....so, until it was made clear , don't expect a CORRECT answer.
And the vented disc use a different caliper, but again, only on some Wagons, never on your Sedan.

<1994 E320 W124 SEDAN, built in 2/94.
And by the way, I do believe there were vented rotors used on some of the W124 wagons. To wit:>

We know that..we did NOT know if you had a Wagon or Sedan...
..and that determines the answer.



I am sure you were simply mentioning that some of the wagons did have vents, but if you go back and read your follow-up post, you will see how it could easily be read [ or mis-read] that you may, in fact, have a wagon..3 posters read it that way...and that is where the confusion came from.
Nothing to worry about and just a tip for new postings.
Your chassis 124.032....a piece of info you may want to include for future post b/c we know by the .032 of 124.032 that you have a Sedan and not a wagon and that makes the short of it......no matter what any following post may or may not indicate.
If you go to the top of this Forum page and click on 'Buy Parts", all the info you wanted is right there by model/year/and chassis. A good part info source we all use , even if just to see what was used on a particular model for interchange.

Mark, you had an excellent opportunity for contrition, and blew it. On forums, as in life, sometimes it's best to just admit the mistake.

Arthur,

The first time I posted on this forum, you responded first and correctly, that I seemed to need a new engine wiring harness. Your experience and willingness to help is not lost on me - Thank you.

Sometimes the initial question gets lost in banter about, but not addressed to, the original poster. I've seen threads in forums that rail on and on about the original poster.

In this thread you referred to me as "he".

I'm not a third person in this thread. I'm the first person. Manners matter to me, especially after spending so many filithy hours wrestling with brakes and wheel bearings, and rusty pins that don't like to behave well.

So, you'll forgive me if I take this small space to protest the manner in which you first responded.

But I wouldn't trade you! So don't go and get mad and never talk to me again, okay?

And thank you again for sharing your considerable expertise!

Mark

Vehicle specificity is always appreciated

and will usually get the poster the correct answer more quickly. I am one of the guilty parties in assuming the vehicle in question was a wagon based on the previous posts and couldn't understand why a 1994 wagon would require solid rear rotors. Deanyel was the first to notice this and Arthur bird-dogged the answer. Thumbs up to both of you.

The other "Mark" in this thread

I am in agreement and I do see how the confusion took place.

We tend to get bent out of shape here b/c in answering a post, we like to be correct. ..and conflicting posts make what is easy, hard....[ which is why I used the "getting thrown a Curveball" in my post.}
But , it is not a big deal and I answer most post regardless of my complaining......

Your first post was fine and contained all that was needed ...and it was basically answered by Dean, telling you the info was right there on top of the page.

....and all is fine here..........
