I got to thinking about which cars this 002-430-68-30 Booster was used on. This thread starts out mentioning it coming off a SD.


It looks like this Booster was first used in 1968 on the 280SL, 280SE and 300SEL and the majority of models through 1985. W107, W108, W109 W113, W116, W126.

What do you think about the "double chamber" booster I found in a 91 w126? Would this be any better than the 60's designed booster I got?

The DOT 5 bottles say "not for use with ABS" on the label. Many have speculated on the reason. Silicone is more compressible than new glycol, though after a year or so the glycol can absorb enough moisture to make that not true. Compressibility could affect the pulse rate of the ABS unit. My guess is that car companies don't spend the money to qualify their ABS with silicone fluid. I doubt there is a seal compatibility problem since the DOT regulates that all brake fluids work in all systems, plus there were some 1950's British cars that required silicone since glycol attacked their seals. One guy said he was going to try DOT 5 in one of his ABS cars. Worst case is probably that the ABS would pulse a bit differently.

I thought ABS used much more volume of fluid (silicone is expensive), but doesn't seem true when I bleed them. It would be harder to get all the glycol out of an ABS unit and many newer cars have dual brake tubes to the rears (X-pattern MC plumbing), so more work to fully flush. In my case, I might sell my older 1996 minivan in a few years (currently use as a truck to haul stuff), so no sense changing it.

Click on the tab above for the catalog, and then look up a 85 300SD and then a 91 560SEL. Notice how many Studs are on each Booster.

The early Booster has 4 Studs and the newer style only has two.
So 85/86 is the change.

Your 91 Booster will not work on the 85 and older vehicles.

i only got the 300sd booster at the yard. i just noticed the 2nd gen one was weird so i did not bother with it. i am very pleased with my upgrade though! i drove our yukon tonight and was very surprised to find it required more pedal effort than what i have been used to for the past day in my car now

No problem. The ATE sticker says "3.6857-1201.4" and under that is "0183H4F"

I wonder why it wasn't used on w123's originally. Fuse box cover is easier to remove too. The only thing I don't love with the install is the large vacuum line is now too long. I had to buy a new one a couple years ago so the plastic is not brittle so maybe I can cut it to take some length out. I'm guessing the line can then be heated and slid back over one of barbed fittings?

Possible - but in my experience with old plastic unlikely (sorry).

I reckon there should be a zero in front of that number

03.6857-1201.4

There are some hits for that number on the interweb but it seems to be pretty rare

This one seems to be the most likely one used in a first gen 300SD

ATE 03.6855-1202.4 (03685512024) Brake Booster

But I don't know what the difference between these two is

I thought I'd add some info, since I just did this and was reading through some threads regarding brake upgrades and this one needs some straight facts...

The 123 and 126 brake master cylinders are the same. Same part number. That's why you can use the "stock" 123 MC. The only difference with the 126 cars is that the ones that have ABS have a different MC, which is neither here nor there for this upgrade.

Also be aware that you'll probably have to do something with the vacuum lines. The too-long 123 main line works, but it does move the check valve/splitter farther away from the other lines and those become too short. So either shorten the check valve to brake booster section by about 2" or make the smaller lines longer. I plan on making a custom main line and then doing some cleaner/more reliable work to the vacuum system. Good opportunity to do that.

I also see no way you can do this without removing the master cylinder completely from the car, so plan on doing a flush, along with any other brake work at the same time.
