'90 300TE-24 (M104) brakes on a W201?

[MB190D]

A friend of mine recently upgraded the brakes on his '90 300TE-24 to Porsche brakes, and offered me his original set for a very good price - but, will they fit on my car ('84 190D)? Everything is included with them..

I have learned that there is quite a difference between the 12V and 24V brakes - but what is the difference? And what is the difference between these and 400E-brakes?

PS: The price for ONE of these calipers at MB here is 1250€/$!!!!!!!

Do you really need big expensive brakes on a 190d? Pads and discs will be quite expensive to replace I would imagine.

What are you trying to accomplish? Mercedes brakes are very well engineered. I've run my 190E 2.6 on road racing courses with Repro Deluxe pads (definitely not the first choice for roadracing, but excellent on the street - no dust or squeal and easy on the rotors) and the brake performance was satisfactory - not great, but okay. If I was serious about more road racing I would definitely select a more suitable pad, but the Merc is retired from track events.

All 190 models have plenty of brake capacity for most any kind of service. Even the non-vented front rotors on your 190D are perfectly adequate for the cars performance potential. The only necessary tuning issue is to select suitable pads for your type of use. Bigger brakes are also heavier, and you have to understand some basic hydraulics and vehicle dynamics to get the bias in the ballpark. Blindly swapping brakes from another model is just asking for trouble.

No issues using 400E brakes on the 2.6, easy install with minimal modifications necessary. You can use 500E and 600SL brakes as well if you want to deal with the hub issue.

I race my 190 and there is a night/day difference between the stock brakes (300E components) and the 400E brakes. I run Motul 600 fluid, PBR Metal Master pads and SS brake lines

For some reason MB found that dieseldrivers weren't going to go fast - and to some extent they were correct, since I'm not playing in the above 150km/h league very often.. But, this doesn't mean that I don't use my brakes heavily - They tend to fade just a wee bit too often for my taste, which is the original reason why I want to upgrade to ventilated brakes.

The reason for me asking about these brakes in particular is because my friend just happened to have them for sale right now - they have near new pads and discs and he's offering them to me at a decent price.

I have now got the brakes so that I can test-fit them - a quick investigation of them indicates that they should fit, but nothing can be said before I actually try.

My questions were simply whether anyone knew if they would fit, and if not what I would have to do to make them fit...

Thanks for your responses though!

One problem you may well encounter is that your wheels won't clear the 24v calipers. Whilst initially they looked the same the wheels from my 12v TE's foul the calipers on my 24v.
A new set of wheels will push the price of the conversion up appreciably.

Good thinking - I need to check that too! I haven't got stock wheels though, so I will have to check physically in order to be sure

Thanks!
