SBC Fluid Flush
Could someone tell me how to use SDS and Flush Brake Fluid. My Mechanic said he does it with a Pressure Tank, but have read here and there and it dont seem the best way.

I'm also curious as to the right procedure to change rotors and pads but more importantly how to bleed the SBC brake system. I talked to a friend of mine he use to be a senior Mercedes tech service mechanic and he said that they just put a pressure bleeder on the system and it works fine but he left Mercedes in 2004 he looked at mine last night and said the systems should be the same as long as you get the SBC to sleep should be no problem. Can somebody else confirm. Thanks for any input

SBC brake bleed
I used the Motive Products brake bleeder on my SL55 and E350. There are forum comments that this does not replace the SBC pressure reservoir fluid on the SL55, but my thought is a frequent flush will eventually remove this fluid.
The 'black' label is the better quality unit than the 'red' label, and worth the cost difference. Search online. eBay or Amazon for the best price. you can also buy other fill pressure caps to fit US or Jap cars.

SBC 'sleep' procedure is attached. Worked for me when replacing pads and bleeding.

Kbob999 thanks for the info and the attachment on sleep mode. I do already have the black label motive bleeder. I have a 2007 sl550 but I assume the procedure would be the same? I'm also going to do a ABC flush at the same time my car only has 18000 miles but I feel better safe than sorry. Thanks again also looking on eBay for a star system but I'm really not that savvy when it comes to that stuff but will do my home work and read up

Just reading through the forums and I see a couple people just unplug the SBC unit then plug it back in when done. Seems to easy does it work? Or do you have to go through the deactivation procedure ? Thank sorry to be a pain but just want to get the right info.

I'm kinda scared to unplug mine as last time I did it (Last Year), it was but a day and triggered my "SBC Warning on Dash" "Visit workshop in white", I went into SDS and it said that threshold was reached. I had to buy this tool to reset Break Pedal Count. As I couldn't read German in that part of Software to reset. Too coincidental for me.

Not sure that caused it, but was way too coincidental. I sure wish someone would post about bleed procedure. I take it just Cap Fluid Tank, apply pressure and bleed away.

SBC unplug...not recommended.
I was also going to unplug my SBC, but broke the plastic locking tab when removing it. Too much heat in the engine bay for cheapo plastic and the age.
Now my SBC plug will not lock in place, but is still engaged. I gave up on that process and used the 'sleep' procedure.
The pressure bleeder is really straight forward.
Engage the sleep procedure.
Suck the existing brake fluid out of the master reservoir by whatever means.
Fill the Motive bleeder with a liter or 2 of fluid.
Screw the pressure cap on the master reservoir, and pump the Motive to 20 PSI.
Bleed rear first, then front.
Remove pressure from the Motive.
Drain the excess fluid in the line back to the canister.
Top up the master reservoir, and put the cap back on.
Follow the 'sleep' procedure finish by spinning the left side wheels to complete the process.
Done.

You do not need to disconnect or disable the SBC to flush the fluid. Using the Motive Pressure Bleeder and the Star Diagnostic system is the best course of action. Next up would be the Motive Pressure Bleeder and just opening the bleed valves on the calipers in the proper sequence. The second course of action will leave old brake fluid in the system.

Missing the link for "this tool". Did the reset tool work?? So you were able to get into developer mode with your SDS, what version or year do you have? Some have said that the developer mode is not available on the newer >2009 versions??
I am researching the purchase of an R230 and want to be armed with all the info that I can find
Thanks,
Bob

I bought my SDS (500.00) on ebay as well as the Brake Count Re-Set Tool (42.00) I have heard that also about Developer Mode but I have it on my 2003 SL500. I can't really say for sure don't play around in that part really thou as I would probably cost myself money by messing a setting up.

Thanks Kbob, awesome instructions!
One question! Do I have to Sleep SBC just for Bleeding?

At the risk of overly highjacking your thread, there is a code associated with the SBC Warning "brake system visit workshop" of C249f which indicates the 300k cycle limit has been reached for the SBC controller. Did your re-set tool clear that code as well as reset the cycle count or did you have to clear the code with your SDS??
Thanks,
Bob

It cleared everything the Red Buttons are for 25% 50% 75% and 100% Reset Count. I was pleasantly surprised how easy it was! Simple to follow instructions. But I would make sure that your SBC is good but exceeded range or you tripped it yourself like I believe I did. Just for yours and anyone else's safety.

Sleep for bleed
Cadbob,
The sleep is not required for bleed, but I'd do it. If the system puts the squeeze on when you are not prepared, it could squirt fluid everywhere. Not good for paint.
You know, that reset tool is in demand for my 86K mile SL55. I'll need it soon. How would you like to sell it to me? I'll pass it on the the next person that needs a reset. Send me a PM or email.

Hi Bob,
I dont want to part with it. I'm sorry, but there are plenty for sale on ebay where I got mine. I ordered mine from China and it came in just a little over a week. I keep mine with my SDS Stuff, as I will never know when I'll need it or hopefully not. They are only like 40.00
