Clutch pedal
Sometimes - but not always - the clutch pedal on my 460 only returns half way after having been pushed down to change gear. When it does not return properly the driver needs to flick it back up with their toecap.
Although I have soaked the return spring and the horizontal shaft in lube there seems to be no improvement.
This can make low speed maneuvering tricky.
Am I missing something obvious, I wonder?
Many thanks for any advice.
Nick.
Seems as though
clutchh master and, or clutch cylinder may have air lock, fluid old or rubber seals becoming supple. Firstly, my attempt would be bleed; renewing brake fluid in the whole system. Should pedal be the same my suspicions would fall initially with the master cylinder. Report back after fluid rewal.
Been thinking about this since you texted me Nick, I think your pedal box may have the overcentre clutch assister Spring which may need lubricating. If it hasn't it may be the slave cal sticking.
It's one of those jobs you'd have to see to be able to diagnose properly, has your friendly spanner had a look?

my g wagon did the same
i know its a 463 but its the same set up basically
the fluid was full but i decided to do slave and master cyl seal kits
Gearbox end it might be cheaper to get a cylinder complete from a motor factor as some interchange
I could not believe the seals did not leak as the rubbers inside were shot. Basically it was the piston pushing clutch as the rubbers were so damaged they did nothing
If i kept the clutch depressed, which i dont as i put it in neutral it would let fluid past and eventually start moving. Lucky i was off road when it happened. No worry but it made it home easy enough as i just did not hold clutch down at junctions
When you pull pedal up from half way im sure it will move easy. If so its the above
I will be amazed if the clutch pedal is seizing up but let me know

Sorted the bad spelling for you .
seals fail within the master cylinder and the slave cylinder so you can have a problem in either without any fluid loss
rubber deteriorates over time, I've had both slave and master cylinders replaced on my ge463, neither are expensive items as they are from the corresponding car model of the era
Nick. At risk of repeating myself, take the assister off, it doesn't need it, Mercedes sacked it off and it that that's giving you the issues.
I have your seal btw

Thank you, Rakesh, as ever. That makes sense to me. I will start by bleeding the master cylinder when I get a chance and let you know how I get on.
All the best, Nick.
