Help please. My friend has Mercedes Benz w201 190, 1989 petrol manual transmission.?

Question

The clutch pedal goes to the floor and stays there when changing gear. Not every gear but quite regular whilst changing up and down. he has tried bleeding it a, a few times no difference, also he has replaced the cylinder much to his frustration no change(pardon the expression). We are both baffled. Can anyone, I just know there is someone waiting for this one to remedy, lets hope. This cylinder is located uder the vehicle below the clutch pedal and is very awkward to get small eight ml spanner in to bleed or try to replace. We have asked about,searched Haynes manual, scratched heads, could it be anything to do with the Servo-Unit? or any other source. This is a nice old car and worth repairing, please any suggestions would be most appreciated. Thanks in advance, Andy.

Update:

extra details, when clutch pedal goes down he has to pull over to side of road and rech down and pull it up this seems to solve for short time.

Update 2:

Fluid kept topped up.

Hi Andy

It sounds as if the spring fingers in the clutch cover plate are worn.

When worn, they fail to return the clutch release bearing back to the clutch out position. When lifting the pedal, you are asisting the cover plate in returning the clutch release bearing back along the input shaft to the clutch out position.


Hope this helps

There may be an actually return spring associated with the clutch reservoir mechanism that has failed or come off its setting. There is also the possibility the pedal rod is being galled by the orifice it passes through. Good luck.
