I am about to change the brake fluid in my 82 240d with manual transmission. I have seen nothing about changing and draing the fluid in/for the clutch slave cylinder. Should it be done also? I guess you would need to depress the clutch? I don't know, so I need some insight.

Thank you.

I would do it while you are at it as the brake fluid in the clutch will contaminate your new fluid a bit. The haynes manual talks about bleeding it by connecting a line (vacuum hose or something) from the right brake caliper to the clutch and reverse bleeding it as if you were doing your brakes. I have done this before with a differnt method, a vacuum bleeder. I highly recommend one. These are available at most auto stores and work very well. Just make sure to keep an eye on the resevoir and get some good dot 4 brake fluid.

the bern,

What ever you do make certain that you use DOT 4 hydralic fluid or MBZ approved. Dot 3 will dissolve the seals in about one year, learned the hard way. Best way to bleed the system is to invest in a MityMite vacuum bleed kit. Then bleed the entire system. MBZ recommends bleeding system every year. The seals and cylinders last forever if you do that as the cylinders never get enough water in them to rust. Bleedint the system with the vac unit takes about twenty minutes and is very easy.

All of the bleeding advice is valid if you need to bleed. It sounds like you only need to flush. To flush, you can do it with a helper the same way you do a two man brake bleed.

Do the clutch AFTER you do the brakes so that you can keep the reservoir full of fresh fluid. This is not a matter of while you're at it so you don't contaminate the brake fluid. It is just as important, if not more so, to keep clean fluid in the clutch system.

Have the helper step on the pedal, loosen the bleed screw on the slave cylinder momentarily, then retighten it. Continue the process until nice, clean fluid is coming out. Keep the reservoir topped off above the nipple that supplies fluid to the master cylinder.

Although it would be good to seek out and use DOT 4, I used DOT 3 for years in 123 cars with absolutely no problems. DOT 4 is now easier to find.

Good luck,
