The calipers on my 123 are SHOT. I have the bendix type. I also have the rebuild kits sitting on the table in front of me. Bad calipers could cause one side to drag, that is what's wrong with mine. The driver front (most likely to have trouble, shortest line) has the outside piston stuck. It wont move in or out. I'm going to have a fun time freeing it up.
I have to get my 126 on the road so I can spend some time taking them apart and overhauling them. It's not really a major job, but it's tricky on this particular type, because you're going to need to keep one piston in while you get the other out. You'll need to find a clamp that will allow that, and keep your fingers out of it when you hit them with compressed air. I read the instructions on the manual CDs, the only thing I'm worried about is that it says the pistons have to be in basically perfect condition. They are supposedly chrome plated. I'm thinking if you carefully buff them that would be good enough, but you dont want to use anything too abrasive or it'll corrode fast and you'll be stuck in the same situation.
Remember. Moisture + heat = instant rust.
I'm giving it a shot anyway, for $15 and a few hours, it's worth it, but i have a funny feeling I'll end up replacing the calipers.
thanks for your advice, i believe my pistions go in and out, but i think there slowing down hense one brake is WAY lower then the other. im going to call mercedes tomorrow and asked them what type of caliper i have. hopefully mercedes is not to expensive oher wise ill two day from offline

The brand should be stamped on the caliper, it may be hard to find after 25 years of rust and gunk.You'll be able to find it with a can of brakleen and a wire brush. I'd be surprised if the stealership can tell by the VIN what brand were put on your car.All mine have been ATE and Girling, I forgot Bendix were put on these as well.

I recently replaced my front calipers on the SD, they were Bendix, but when you replace them, you do both fronts, or rears. So you can put whatever you want on.
I understand MB used Bendix and ATE. Girling is the booster manufacturer, didn't know they made calipers as well. Anyway, a difference between Bendix and ATE is the shape of the retaining pad spring, the Bendix used a wire bent to specs. ATE used a flat, wide piece of spring steel.
Hope this helps.
