Sbc braking system or not?

[zipdip]

Ok I will ask the question is it possible to fit SBC on a Mercedes when that was not original equipment,I have never heard of it being done,.

I think probelm is get SBC/ESP to communicate with ecu

Anything is possible if enough money is thrown at it, but why would you want to?

No one in their right mind would want to retro-fit SBC.
SBC is the most weird user-unfriendly system imaginable.

I've had crazy answers from parts people at MB main dealers in the past.
I once needed an ABS sensor for a Type W126 380SE ...... only to be told by MB (Bradford) that my car was not fitted with ABS when manufactured.
Fortunately I got more sense from Euro Car Parts who got me one within 24 hours.

SBC works very well, though the brake pedal is lacking in feel; there's nothing weird about it. It's rather technology for technology's sake, though, and a solution to a problem that doesn't exist; properly designed, standard servo brakes are perfectly adequate on any car.

SBC braking is fantastic, one can really feel how it 'helps' the car in very fast corners.
I had the odd occasion in my CLS55 to have to stop quickly from 'quite' high speeds, remarkably safe and consistent.

Interestingly I have a similar system on my Lexus hybrid. As the engine isn't always running the hydraulic pressure is generated and stored just as in the SBC system..

The braking on my E280 CDI Sports Estate is absolutely awesome.
I've only had to use it "in anger" to its maximum capacity a couple of times (thankfully !).
It was faultless.
Simple to understand ... Simple to maintain.
Why go for an unnecessarily complex system where you need to connect to a star machine to bleed your brakes ?
and ...... after so-many brake pedal operations - needs an eye-watering costly repair that you cannot do yourself.

In the words of Robbie Coltrane, playing Dr Johnson in Blackadder Ink and Incapability:

"Like fitting wheels to a tomato — time consuming and completely unnecessary"

Indeed.

Not unless it was just a simple component swap ....

(And it's not - so retrofitting is not a practical solution).

SBC was remarkable.

It is widely misunderstood.

Not here it is not.

Love the brakes in the W211 cars and would have no quibble now about having to have an SBC pump refurbished.
OK I say that now, I'd likely still moan at the time bit for the record SBC is fantastic, best braking system ever developed in the whole wide world, honest.

 

[OneForTheRoad]

Sbc was fantastic. The braking effort was unreal.

The following is cut & paste from an earlier 2012 thread on here:

The text from WIS (Document SN00.00-P-1047J — Overview of innovations/changes 06/2006) reads:

Model 211/219
As of code 807 Model year 2007

Introduction of Adaptive Brake (ABR)

As of the model year, the previous SBC brake system is replaced by the further developed Adaptive Brake system. The comfort functions "Hold" and "Dry braking"
from the current brake are retained. The ESP control unit and the traction system hydraulic unit are now a compact component.

In vehicles with ABR brake, the driver is made aware of ABS regulation by pulsation of the brake pedal.

The new brake system is bled without STAR Diagnosis. Further information can be found in the WIS.

I'd forgotten about that.

Slightly odd sensation when braking at stop/start traffic speeds sometimes.

Yes I find that it is lacking in feel, particularly under load when coming to a stop, such as a traffic light. It is very difficult to modulate the pedal and maintain the level balance in the car without lurching.

That said, the system itself is excellent overall and I love the SBC H(old) function.

Yes, I remember thinking it felt a bit "binary" at times (again, at slow speed).

Great system though.

I liked the hold and I also liked the fact the car would never roll back which I think I read was a feature of the transmission.

 

[E55BOF]

I rather think the SBC Hold feature applies the brakes and keeps them on slightly, which is why the car doesn't roll back. However, as with many automatics with decently torquey engines, the car doesn't roll back on a slope unless it's fairly steep purely because of the torque at idle. That's why it creeps forward on the level unless the SBC Hold is used.

 

[bolidemichael]

The car will actually roll back (without SBC H applied), if on an incline and the transmission is in C mode. That's because it's is effectively in second gear.

 

[John]

I'm sure it seemed as if it slightly bounced off something which stopped it rolling back - which I thought couldn't be the SBC+H as that would just hold it.

My subsequent cars both roll back but they both have 7g+ and are usually in 2nd.

Sounds like it was in Park and took up play on the parking pawl
