W463 Brake Master Cylinder
Good day all -
I have a 1992 300GD, W463.328. After rebuilding the axles and front brakes (these were the Perrot calipers and with the standard kit of seals and pistons, they rebuilt beautifully) , I am now in need of a new brake master cylinder or a rebuild kit. After much research, I am left confiused.
p\Part numbers from MB say 005 430 38 01 and 005 430 44 01 for vehicles with antilock brakes. My vehicle has the antilock servol..
For vehicles without antilock brakes, the part number is 005 430 29 01. This is an ATE part, number 03.2125-2102.3.
Confision point 1 is that the brake part numbers seem to wander between 005 and 004 as the leading digits, yet the parts seem the same. There are also several parts listed (i.e., teh 38 01 and the 44 01 parts both being the same function) yet, EPC doesn't list one as superseding the other...
Confision point 2 is that the only unit I can seem to find anywhere is the 29 01 part number for vehicles without anitlock brakes... I cannot find a 38 01 or 44 01 for use with anitlock brakes.
Confusion point 2a is that the master cylinder on the vehicle now looks IDENTICAL to the 29 01 part that is supposed to be for vehicles without antilock brakes, yet my vehicle has anitlock brakes.
Can anyone help with the confusion? What is function difference in a brake master cylinder when used with or without an antilock servo?
Thanks so much for any input.
...Mike.
Send me you VIN and I will look
LHD and RHD differ
Manual and Auto sometimes differ!
Early and Later types differ with internal bore size although look identcal
ABS different again...
There is only one RIGHT one in theory!
Most will certainly bolt up and can be made to fit.... but MB designed all these difference for a reason ;0)
Chassis number had a digit missing off the end so assumd its WDB 463328 17 082590
German market LHD model sold new in Frankfurt
So A005 430 38 01 is the correct number
No longer available at MB
Optional number A005 430 32 01 also NLA
Cylinder looks to have been around £520 when available
G specifc part and fits only early 463 and some similar era 461 models
Can't find any aftermarket options available and the odd supplier that lists it new MB is just pulling from the MB price file and when you order they will take your order and then decide in a months time they can't supply and you will eventually get your money back... ask me how I know!!
There is a Repair kit A005 430 37 01 that is available in Germany at MB at around £315 and this is the only viable option I can come up with for you!
A dealer should be able to get you one in a week or so and I am sure will be a comprehensive kit and will make it as good as new!
Or shout if you need assistance...

Hi Mike
Glad that was helpful.... makes the effort worth while!
The part number digits all mean something yes... but it's very Germanic and not so simple
Basic format you dont even read the part number numerically as such!
A005 430 38 01 is written but MB would like you to read it A430 01 005 38 !!!
In this case 43 is the group for Brake Parts with 42 being main components and 43 lesser components
The 0 is then how important that component is... So 430 is a lesser component but quite important one! Where as 439 would be a small component and 420 a major one.
The 01 would denote what type of component, so a xxx 430 xx 01 will always be a Brake Master Cylinder or Kit
005 in this case is just a generic number, it's usually used to identify the first type of vehicle the component was degined for so if that was 463 then it was first designed for that model... but not neccesarily solely used on that subsequently
If this number is 000-099 it is usually just a generic number to fill the sequence or a standard part... so strange in this instance that it isn't 461 or 463 but they would have a reason! Perhaps it was a designed component without a home until they fitted it on the G or it was an off the shelf component used by the supplier for another manufacturer...
The 38 is specific product and supplier detail... so if that cylinder was supplied by two different manufacturers then they would have a different number there, so A005 430 38 01 might be a Brake Master Cylinder made by ATE and if there was also say a BENDIX one that was the same exactly it might be A005 430 39 01 for example
There is a lot more to it and most dealer personel would not have a clue!
The groups are from 01-99 so the second three digits you can look at a part number and tell what sort of part it will be... with 35 years experience you just about remember them all !!! Or probably starting to forget them now...... so xxx 180 xx 09 will be an engine oil filter... xxx 201 xx 80 will be a water pump gasket etc
My daily job in parts running a £35m turnover dealership group doesn't so often allow me to keep my hand in with this skill set (HR normally) so helping on G stuff as a hobby and pastime helps me keep my eye in so to speak!
PS I can't see them selling them all very quickly
But the factory only have 10 repair kits left and when gone I imagine they will be NLA
Not always the case.... but!
What with? My powers of Anorakness ;0)
Likewise, live and learn after many years. Very Germanic indeed. Thanks Gav.
A little more detail for those not bored yet!!
The Mercedes-Benz Parts Numbering System explained
Each Mercedes-Benz spare part is assigned an identification number,
used for ordering the part. These part numbers follow an ordered system,
as the following:
1-Basic Numbering
2-Sorting order
3-Letter prefixes
4-Suffix Numbers
1-Basic Numbering
The most common part number has 10 digits and a letter prefix Such a part number is written as follows:
A 117 030 10 17
Note the spacing and grouping of the digits. When spoken, you say it as its written, like A- one-seventeen, oh-thirty, ten, seventeen.
Most people used to MB part numbers will say it that way, and saying it differently tends to confuse.
Each section has a distinct meaning:
A -Prefix for Passenger Car parts. Other prefixes (such as B, C, N and W) are explained below.
117 -Type Number. This is the internal type designation indicating which vehicle type for which this part was first designed.
Parts may be (and often are) used in other types. Some parts use other numbers unrelated to model types.
030 The parts group number. Major group 03 corresponds to the EPC group to which the part generally belongs. The third digit indicates
(broadly) the type of part from that group.
10 Modification Number. This identifies the modification status or variant of the part. The first version or variant is generally numbered
00, and numbers increase with new variants. A higher number does not necessarily mean the part is newer or better, it is assigned somewhat randomly and not all numbers are assigned or used in strict sequence.
17 -Part Type. Most similar parts of a certain type have the same type number. In this case, part type 17 (in group 030) is a Piston.
2-Sorting order
When sorting a list of 10 digit part numbers, use the order shown:
A 117 030 10 17 will be sorted in the following order
117 will be Third
030 will be First
10 will be Fourth (last)
17 will be Second
For example, first put all part numbers in order of the second group of digits (030), then sort within the group by type (17), then by Type number within Type (117), and last by Modification Number.
That makes Sense!
All other part prefixes (such as N or B) are sorted in direct numerical order.
Examples of the spacing and grouping of part numbers with other prefixes are:
B6 782 0415
BQ682 0116
HWA202 545 27 19
N004019 013802
W210 589 03 29 00
3-Letter prefixes
Use of the correct letter prefix is essential. While most parts are numbered uniquely, some may be duplicated with different letter prefixes.
The map to the treasure:
A Passenger car parts
B Accessory parts
BQ MB-USA Domestically-assigned part numbers
C Commercial vehicle parts
HWA Special passenger car parts (generally AMG)
N DIN (German Industry Standard) parts
Q Not a valid part, used as a placeholder in some EPC catalogs. Usually 12 digits, often all zeros. Do not confuse with BQ part numbers.
W Special tools
X Some commercial vehicle & light truck parts
4-Suffix Numbers
There are two kinds of suffix number, known as ES1 and ES2. A part generally uses only one or the other, but both may be used for a single number. ES is an abbreviation for the German words Erganzungs Schluessel, which translate as Supplemental Key.
ES1 codes are always two digits, and always immediately follow the base part number. The ES1 is sometimes called an Index number in the literature. Some ES1 numbers can be used to designate a specific version of a base number, such as for Pistons or Springs, which can be supplied with slightly different sizes or values. The meaning of some common ES1 codes is as follows:
05 Special demand part. Often used to denote parts supplied for a service action
10-15 Package sizes for a base number. Often used for service fluids
26-28 Component that is pre-programmed or specially prepared
64-69 A part identical to the base number, but from a different supplier or location
70 A core with value which should be returned for credit
80 A re-manufactured component, which also has a core value.
81 A re-manufactured component, which does not have any core value.
87, 88 Same as 80
90 A re-manufactured part with no core value, often used for Warranty repairs
ES2 codes are always four characters, with digits and letters often mixed.
These are always placed at the end of the entire part number, after the ES1 number if necessary. These are most commonly used to denote the color and texture of specific parts which are supplied in different colors and/or textures. The correct ES2 code must be specified to receive the correct part. These are sometimes called Color Codes not to be confused with paint and trim color codes. Some parts have an ES2 code of 9999, which generally means that the part is provided in primer and must be painted.
Here Endeth the lesson
Not my write up... but as I would have written it!!
Blimey!
I think I'll stick to asking Gav
Hi Mike
It is the 82,590th G Wagen built all models 460 / 461 / 462 / 463 / 464
Still running in the same format today? serial numbers over 400,000 now
Thanks
Gav
No unfortunately not!
They all run 17 digit VIN numbers... think from 1981 when the original WDB world manufacturer prefix came in....
Pre 1981 they were just 14 digit VIN's
WDB = West Germany Daimler Benz... obviously there are many MB prefixs now depending on which country they are made
The 11th digit is the factory of origin so all G Wagens built in Graz have a 7 in this spot
Even the PUCH badged cars that have a VAG prefix which was Austria and Steyr Daimler Puch for G and Pinzgauer and nothing to do with Volkswagen Audi Group as some people state! The VAG chassis PUCH G still had the 7 in the factory locator digit but the 6 digit serial started with a 9 so ran from 900001 to just shy of 915000 when they stopped badging as PUCH in all markets that the agreement with MB ran in, which ended in 2000
The cars of that era could have different factory's so usually had an A or F in that place from 1981
So they could run two different serial sequences if the model was produced in multiple factories or serial runs if volumes required
So say A000001 - A999999 or F000001 - F999999 then they rolled around to B,C and so forth
Early models prior to the factory locator digit had a 0 or 2 in the 11th digit when there wasn't as many factories
0 was manual and 2 was automatic transmission.... this also applied to the 8th digit of the engine number
Just like the 10th digit of the VIN is either 1 for LHD and 2 for RHD and this followed with the 7th digit of the engine number
Multiple models of the range could be built in the same factory so A000001 - A999999 could be models from different series 123, 124, 126, 201 etc so harder to ascertain how many of other models were produced from VIN serial
Think A.B.C and F where all Sindelfingen and G was Breman
North America run a seperate format so these start WDC when the G was offically imported to the market post 2002, in general and the 11 digits mean different things although the serial will remain in the same sequence! So North American G's will have 2 VIN numbers (one sometimes called a FIN) that look completely different apart from the last 6 digit serial... the NA VIN has more letters in it
Another G exception is the mainly military built under license 462 series that usually still had a WDB prefix and standard serial like for the Greek assembled ELBO ones, But some serials started with a 6 so 600001 - 613xxx for the French supplied P4's although these got a Peugout VIN when completed! Again in some markets these 60000x serials have been duplicated with a BR1 prefix more recently like Algeria although technically they were not used first time around...
Another quirk to see is the 10th digit being a 5 or 6, these are LHD and RHD again but vehicles supplied from Germany in SKD (Semi) or CKD (Complete) Knock Down or "Kit" form to be assembled in local markets... for example a fair few G's supplied like this to Indonesia... you will also see some 124 series like this that pop back up in the UK in RHD... these are often late models of each series that the market continues to sell even the general worldwide production has ceased.... so you will see some P and R plate ex Indonesia assembled 124's in the UK even though UK sales stopped on an N plate in general
All very complex!
First 460 serial 000001
Last 460 serial 083513
First 461 serial 011058
Last 461 serial IN PRODUCTION but past 380000 but now phased out to 464
First 462 serial 051265 / 600001
Last 462 serial 104056 / 613245
First 463 serial 064876
Last 463 serial IN PRODUCTION but past 400000 as the "463a"
First 464 serial 330321
Last 464 serial IN PRODUCTION but past 400000 as the new "461"
First 465 serial 000001
Last 465 serial IN PRODUCTION early stages as EQG
First PUCH serial 900001 all models 460 / 461 / 463
Last PUCH serial 914222 all models 460 / 461 / 463
So you can see that the different series productions often overlap so you get hybrid versions as new models equipment is incorperated into series run out of the previous models... for example late serial 460's from 064xxx had some 463 parts incorparated as the 2 series ran parallel production until the 460 was phased out...
Hi Gav - thanks for the response.
The VIN is WDB 463328 17 08259
Engine no.: 603931 10 002515
Transmission: 717439 16 051108
The paint code is 9147 - perhaps there is a special master cylinder for these Arctic White vehicles!
