I just ran both numbers through EPC and they state "nothing found". That means that it might be a valid number, but since it is a European part number it is not available in the U.S. market.

Thanks for looking in to it.

This is the sticker on the booster I have got that's from the ML320 in case I've been supplying the incorrect information from it. Is it of any further use?

Cheers.

Here is the listing for the booster for your year and model.

They must have changed the numbers and you cannot refer to the old number.

As long as the booster you bought came from a 2000+ ML there shouldn't be a problem.

Of course disconnect the Master Cylinder from the booster, but do not disconnect the brake lines from the Master Cylinder. The booster can be removed with a little finesse and it will save you from bleeding the brakes.

Thanks very much for taking the time out to help here. I think I'm going to source a replacement direct from a diesel ML just to be absolutely certain its like for like. I made a call to an MB parts specialist in the UK and they seemed to have the same result of not being able to cross reference older parts details.

Try P/N A0014313160 for the seal.

The seal you recommended goes between the master cylinder and the booster.

The seal that is causing the problem is at the rear of the booster, which is not replaceable.

Hey allApologies for resurrecting this, but I have the same hiss in my 99 ML320.


How serious is this? I mean, do I need to fix it now, or could I wait a while? Idle doesn't seem to be affected...

The choice is up to you, but I would consider it serious. You will not receive the full braking force if the brakes are applied in a emergency stop.

Any loss of vacuum will affect your fuel trim.

I'm able to lock the wheels as things stand (well, to get ABS to kick in). The hiss is quite soft, seems like quite a small leak but I assume it will get worse with time.


The price of a new booster is insane (20% of what I paid for the vehicle!) but we have companies here that will rebuild it with a 1 year warranty for 1/4 the price of a new one ...

I repaired this seal in my ML 270 and the leak has stopped. The performance improved dramatically as the turbo was effected from the lower vacuum that was available prior to the repair. I trust the repair will work for a while.

Ok I'm going to try the patch repair. If/when it gets worse, I'll look at rebuilding the booster. Thanks

I tried to work through the manufacturers of the boosters in USA. My vehicle is a US build.
To this time I can drill down far enough within the company but I came to a brick wall for simple part. Use a fair proportion of rubber grease on assembly and it may help on the installation as well as help seal- just take your time! Greg

Mine was also built in the US (I think they all were, weren't they?)I have a place here that's prepared to remanufacture the booster, with a 1 year warranty, for about 220USD. Going to keep that option in reserve, but will try the patches first

Hey, I been watching this thread and finally decided to register and ask. Some here here stayed that any 2000+ ML breakbooster would work.

I have found one from 2006 would that work since the part number i got A163 430 06 30

And the one i found is a A164 430 14 30

Edit.

Never mind the booster itself is different.

Just an update, I pulled the booster out on wednesday evening and dropped it at a brake and clutch centre on Thursday. Picked it up again yesterday afternoon and reinstalled it - leak gone. Cost me about USD330 to do, with a 1 year warranty. I think that's a pretty good compromise, considering a new unit here is USD880 ...

Was able to remove it without disconnecting the master cylinder

I know this is thread hasn't had much action in an age but I've found a replacement brake servo gasket, the one from a Volvo S60 is identical, so the question I have is how do you fit it?


Manufacturer is TEDGUM if anyone is interested

Sorry to resurrect this again but I've been reading the posts and I'm still not entirely sure what to try first. Is it really viable to try a temporary solution until I can afford a new brake booster? If so, does someone have a video guide or something like that somewhere?
