Sbc pump on the w211

[HellsingB]

Hey guys i need some knowledge about how the sbc pump works in a w211 and what it interfers with, money is no problem here, but i want to swap it with a normal abs pump cause i dealt with the sbc and in the part of the world i live in mercedes doesn't warranty it, anyway what i want to know is how to swap it, i know it interfers with the brakes of course and it doesn't have a servo, what else should i check, beside the ones mentioned before, the rotors, the calipers, the pedal as well, brake lines, are there any other electronics? Does it interfer with the esp as well ? If so does it involve the diff ? I know it also needs to be coded out other than this shenanigans xhat else i should do?

I don't wanna trade it with the facelift cause it's africa and all the maintenance is shady so there it is lol any help would really appreciate it, money isn't an issue cause i can always sell whatever parts i'm swapping, they're easy to sell here thankfully

It seems to me that you've jumped to a solution, missing out the requirement step.

I suspect the requirement is something along the lines of "I want the best way to ensure reliable brakes" and the potential solutions include:

1. Get the SBC replaced or refurbished;

2. Remove the SBC and try to configure the rest of the car to work with its replacement.

It isn't clear to me that 2 is better than 1.

I just did a while ago i replaced it with a used one and it worked whatever time it had and now i need to replace it again, considering i'm keeping the car as a project car for future swaps/upgrades i don't want to lose much money or time to look for a new one, it's why i wanna get rid of the sbc completely so i don't deal with it anymore and honestly i'm better off buying whatever parts there's to buy to swap it with a traditional abs pump than to buy another sbc pump, it's why i'm asking and trying to see if i forgot anything when it comes to parts, cause i know it's feasible and it's just about a time thing, i'd basically just need the whole braking system from a facelifted one which there're lots of 'em here where i live and for a cheap price than the sbc pump for ex : a used sbc pump (not refurbished) is abt 350-400 bucks vs a whole braking system from a facelifted model will be about 500-600 bucks tops, with an additional 50 bucks to 100 for the mechanic, so the 700 bucks vs the 400 bucks and the first one will last forever vs the second which is abt a year or two and then replace it again, i'd really take the first choice lol

I suspect it would be cheaper in the long run, and much easier, to sell the present 211 and buy a facelift version without SBC, than it's going to be to swap out the SBC for another system entirely.

There's a company in London who can overhaul the brake accumulator motors on Toyota 4x4's that have a not dissimilar braking system, whether they or someone else can refurbish the SBC pumps on Mercs i don't know, but if it can be done here then you can be surethey do in other countries where they don't throw everything away before it's past 1/3rd life.

I believe the SBC doesn't usually fail as such, if i recall correctly its pre programmed with so many operations before a warning lights up, presumably this errs on the side of safety, i have heard of people getting their current SBC unit 'reflashed' as it were to allow another so many operations with the same unit in place.

It's not cheaper to trade or sell and buy the facelift version as most don't wanna sell it cause they're still unkillable basically, and they're all expensive, they're abt the equivalent of 11k usd funnily enough a w212 e220 cost the same it's why i don't wanna bother looking for a facelift and would like to know what else the sbc is in charge of any idea mate ?

To reply to the refurbishing nope i'm done spending money on it, cause an abs pump will surely be much better in the long term and more reliable as i stated above abt the prices
