I have a 1982 240d. The attached picture shows the brake reservoir and a hose attached to the drivers side of the reservoir. The hose is dry rotted so I need to replace it but I'm not sure where it goes inside the vehicle.

It passes through a big rubber grommet. It almost looks like its some kind of over flow hose but that wouldn't make sense.

Any ideas?

Thanks.

That is for the hydraulic clutch. Goes to the slave cylinder.

Right, except it goes to the master cylinder not the slave.

It goes through the firewall and down to the top of the master cylinder behind the clutch pedal.

Okay, I've sold my 240 years ago, but it seems that line is coming from the master cylinder.

The hose isn`t under any pressure, just gravity flow to the MC on the Clutch Peddle.

Remove the under dash knee panel on the drivers side. Shine a light up there and you will see
where it connects to the MC. It just pushes onto a plastic nipple.

Remove your carpet first before removing the hose and have rags to catch the fluid.

Be gentile pulling the hose off the MC nipple, it could be brittle and snap off. One member a while back had that problem.

The line goes from the brake master cylinder reservoir (pictured) and goes through the firewall down to the clutch master cylinder mounted up and behind the clutch pedal. The brake master cylinder sits under the reservoir and actuates the brake calipers (which are slave cylinders by definition) and the clutch master cylinder sits behind the clutch pedal and actuates the clutch slave cylinder which is mounted to the transmission.

By definition the master is the cylinder that force is applied to directly, and the slave is the cylinder that the force is transmitted to hydraulically.

Thanks for all the replies. It fell off and i re-attached it to the reservoir but it's not a tight fit because the line is brittle at the end.

I'm not sure how long the line was off the reservoir. Hopefully I didn't damage the clutch master cylinder.

The line looks to be a cloth braided rubber line. Similar to a fuel line. I probably need about 2 feet of line.

Is this something I can pick up at Advance auto?

Thanks again.

Pete

Yes, you can use bulk hose. It needs to withstand brake fluid.

Take the bottom panel off and ensure the other end of the hose is attached to the clutch master still.

Hopefully you washed off any brake fluid that spilled out as a result of the hose popping off.

Thanks for the clarification.

No big danger. If you have a leak in the slave circuit you'd eventually run low on fluid and lose clutch action. The clutch would stay engaged all the time until you fixed it.

I asked the same question a while back:
1983 240D - Rubber hose from brake fluid reservoir to clutch master

Forum member crazy4diesel was kind enough to point me to this:
N203501 - VW Braided Brake Hose, 7mm ID, Per Foot

I bought some and have no complaints with it.

When I dropped the panel under the steering wheel, there was an electrical box and I don't think it was connected.

Do you know what this box is for? I plugged it back it when I screwed the panel back in.

Thanks.

That`s the Cruise Control amp box.
It usually bolts up to the left of the Brake peddle. When you have the Clutch Peddle, then it is installed on that panel.

There should be a plug some where under there to plug into the box.


Next time you are in a PNP, take a look at a 300D, you will see what Iam talking about.

Thanks. The cruise was disconnected under the his so that makes sense why the box was disconnected.

Mercedes Benz actually has an updated hose for that application that is made of a corrugated plastic instead of braided rubber. The updated number is 003 997 12 52. keep in mind that replacing this hose may require you to re-bleed the hydraulic system as it will introduce air into the line. which is not necessarily a bad thing as these old clutches rarely get routinely bled.
