Brake Caliper question on W201 190E?? - PeachParts Mercedes-Benz Forum

jeff-abalone · #1 07-23-2005, 01:57 PM

Hi! anyone know that can i use W210 E55 AMG front caliper on W201 190E??? Are they directly fit???

I know that W124 400E caliper will fit W201 190E, but i have W210 E55 AMG front caliper and want to make sure it fit before put on my car. thanks

i doubt they're a direct fit since the 210 uses a different hub assembly than the 201. I could be wrong though. If you've got them sitting there go try them out. Its not as if its hard to remove the calipers on a 201.

You won't know until you try. I don't know of anyone that's put W210 brakes on a W201.

I've just put 500E/EvoII brembos on my 2.3-16 and they were bolt-on. The hubs & spindles were differnet (2.3-16 specs hubs & spindles from W124 while a 500E uses R129 hubs & Spindles) and I only had to change the calipers, pads, rotors, splash shield and pad wear sensor wiring.

They may fit and bolt on, but remember that W210 chassis brakes are engineered as a "front-mount" caliper system and the W201 chassis brakes are a "rear-mount" caliper system. Very different design principles in leading/trailing brake applications. Pay attention to whether or not the W210 caliper pistons are different sized, if they are, it may not be wise to install them in a "rear-mount" position as they will be reversed.

Well, since our 500Es are W124s and not W210s, it's a moot point as W124 front calipers were also rear mounted.

think front or rear mount will matter as the wheel turns the same direction in either case. but placement may be a problem with other things that might interfere such as the hoses and suspension parts.

2 weeks ago i fitted new w129 600sl rotors (price is low, i think, about 80-85 dollars for original MB parts, here in the Netherlands, with a bit of discount) with brand new porsche calipers (the red ones, of the 911/993) which i bought on ebay.de.
I believe the 600 sl rotors (321 milimeter) are bigger than the E500 rotors (300 milimeter?), but i am not sure.

Installed the set with home-fabricated brackets (and lose the thin plate cover) and brake hoses from an Opel (european GM), and drove my 190 2.3-16 on the track in Holland one day. Am very, very pleased with how it brakes now, but it can always get better.

Now I plan to do the same trick on the rear end: 2 days ago i ordered 1 rear rotor from a 129 600 sl, to see if i can use it. This disc is 300 milimeters and VENTILATED! The inner park brake stuff maybe fits, altough the park brake segments for a 600 sl are 5 mm wider (but same diameter i've found out).

300 mm means that the rear brakes will be BIGGER than the original front brakes of the 2.3-16.

I have still got 2 rear calipers from a 944 turbo (also brembo four pot, but a bit smaller than the ones i have on the front) which probably will fit on these rotors.

When these bigger brakes on the rear are also installed, i only have 2 worries:
better suspension and power!

Later model 500E's (mid production year, 1993) were shipped with 320 mm front brakes as compared to the earlier 500E's 300mm fronts.

Forward or trailing mount does matter on a lot of multi piston calipers. Most mulit piston calipers have smaller pistons on the leading edge of the pad to offset the tendency of the rotor to pull the leading edge of the pad into the rotor. By having a slightly larger piston for the trialing edge it offsets the pull of the leading edge into the rotor. Mounting those type calipers backwards only exacerbates the uneven wearing of the pads.

be rotating the caliper from the front of , say the rf wheel to the back of the same wheel. this will not change the rotation as relative to the disc or caliper. if you take the caliper and move it to the other side of the car then you will be changing the rotation as it relates to the caliper and disc.

I was assuming r/f to left rear. That would keep the bleeders upright and would be most peoples inclination. In the case of staggered size pistons such an install would wear pads quite abnormally.

Granted, but the front calipers are usually larger than the rear calipers for 2 reasons:
1) weight transfer under braking means the fronts take on most of the load
2) generally speaking, front brake bias is preferable to rear brake bias

As a result, "rotating" calipers from front to rear is not really a recommended course of action, so your point is pretty moot.
