On a 81 240 D can anyone tell me how long the clutch slave piston should be.


Thanks

Have you ever replaced it on a 240d? I ask because I did, and it was an education. You need to reverse bleed the system, forcing the brake fluid through the top, down through the clutch slave and out the bleeder -- and do it a bunch of times to get every air bubble out.

If you need any help with how I did this I'm happy to help -- it was truly a couple weeks of working on it and trial and error.

You are very lucky! I replaced both the master and slave. Tried to bleed it myself, no go, then brought it to a Mercedes shop, and it was pretty good. Then I tried to make it better and instead made it worse. Then I did the reverse bleeding and now it's great. I think if you replace both cylinders is where you can get into trouble.
