Also, you can go into service reset mode (holding down phone + call buttons while ignition at pos 1 or something) and that code BG should break down into service item numbers. There's a post somewhere on mbworld that deciphers the item numbers into brake fluid, sparks, filter etc. Will post when I find it.

Is it safe to say this is the maintenance summary from the service sheet:
Every service: Change engine oil and oil filter
Annually: Brake system: Replace brake fluid
Every 40,000 miles/4 years: Replace air filter element, Automatic transmission oil change
Every 50,000 miles/5 years: Replace spark plugs
Every 120,000 miles/12 years: Replace fuel filter, Replace main circuit coolant, Replace low-temperature circuit coolant
Is that correct?

Brake flush every 2 years unless you’re tracking
diff fluid every 4 years

Hi,
Both are true. According to official AMG guidelines.
GT / GTS / GTC like all MB, exchange with MB brake fluid after 2 years.
(according to Bevo, no other brake fluid has an approval)
GTR / GTR-Pro / GT - BS
Annual, with CastrolSRX React SRF
(Funnily enough, yes -> no MB approval )
Best regards
Stenzel

Many dealers do not know that the GTR / PRO / BS Castrol SRX should. It is not in the MB-WIS.
Also, Castrol
In my opinion: it makes no sense, as prescribed by Mercedes, to differentiate between models. (GTR / GTS and 1 or 2 years)
All GT models have the same brakes (early GT with 360 mm steel front brakes excepted) You can choose steel or ceramic for all (Pro and BS always ceramic brakes)
If you only drive on the road, any DOT 4 brake fluid will serve its purpose.
The MB brake fluid is no different. It´s filled in every MB. Even in the smallest A class. It's really not a magic potion. If you change after 2 years you are always on the safe side.
If you are on the race track, Castrol SRX or similar brake fluids and a short change interval make sense. Of course also with GT / GTS / GTC .
In short, the intended use is decisive here, not the model.
Best regards

The one thing that is slightly different about MBZ brake fluid is that it comes in a metal container and has a screw-cap that seals exceptionally well ... all leading to virtually zero moisture penetration/collection while it sits on the shelf, even after being opened. I don't know of any other brake fluid that comes in metal containers (though that's by no means conclusive). Regardless, as Stenzel indicates (within the same class/type of brake fluid), it's the wet/dry boiling point versus the usage (street vs track+frequency) that dictates the actual requirements.
The MOTUL people indicate that they fill the dead-air space with nitrogen (IIRC) to enable a 2-year shelf life on their 6xx series fluid. Whenever I purchase brake fluid (normally MOTUL), I immediately use electrical tape to extra-seal the cap while it sits on my shelf thru the "track season" (one could say there are 2 car-related seasons -- track season and road repair).
FWIW, even though I live in a "rain during fall/winter/spring" climate with my in-garage relative humidity pretty steady at 70%, I've never seen any moisture content indicated on my conductivity-type moisture-content "pen" when checking old the brake fluid extracted from a Mercedes. This includes after 3 years (!) in a faithful ol' 1983 300D Turbodiesel that I daily'd for 27 years. In my limited experience, Mercedes brake systems seem to be very good at avoiding brake-fluid moisture absorption.

Hi,
Good argument from practice.
I use (except GTR -> CastrolRSX React SRF) only ATE SL6. This is DOT4 and slightly lower viscosity. Especially for vehicles with ABS.
And that's like all ATE brake fluids in a sheet metal container.
Maybe the MB brake fluid is from ATE. Since ATE is also a Mercedes-Benz OEM manufacturer, that would not surprise me.
ATE (Alfred Tewes) is an old German manufacturer of brake parts. In my workshop I use for all other vehicles, mostly brake parts from ATE. (The only alternative is Brembo)
ever had any problems with it. Fits, works, fair price.
Best regards

Do you track your cars? I only ask because the ATE brake fluid we can generally buy here in the USA simply will not hold up on a road course. Perfectly fine on the street of course, and when you could buy the two distinct colours, gold and blue, it was brilliant for knowing when the specific brake line was flushed.
Endless 650 comes in a metal can, or it did a couple of years ago and is a phenomenal brake fluid.

What are we all running for light track use? Mainly street.
My front and rear rotors + pads are about due, so looking for options.
TIA

This setup works well in medium to high temperature areas (spring to fall in northeast USA). When the rotors/pads are cold it has very a similar grip and stopping distance to the oem setup. As they warm-up, the grip and bite increasing nicely without the harshness of a full-blown racing pads. IMHO, these is a very good setup for street/racetrack combination setup.
When cold outside, 40F and below, even that I use Liqui Moly 20240 Liquimoly Brake Anti-Squeal Paste, they will squeal a bit. This is the only downside I could find.
