You can do it by youself by moving/pushing the lever (that activates the master cylinder) while lying under the car and releasing / opening the bleeding valve (10mm) on the slave, it works the same as a clutch, I attached a youtube video to help

Dean -Just watch out -brake fluid eats paint.
Probably best to get both diff locs flushed and bled with new fluid, and while you at it -flush out the brake system too.

Old hydraulic lines can cause intermittent disengagement. Just be mindfull of this as this minor fault can result in very expensive repairs as it ultimately damages the locker / bearings / crownwheel & pinion

+1

Seen this on old mogs too - the old hydraulic lines look fine from the outside, but the rubber swells on the inside blocking the flow of hydraulic fluid. First symptoms are normally binding brakes (or slipping clutch) as the pressure from the booster is enough to force fluid through the pipe, but the fluid cannot return to release pressure on brakes/clutch.

Most hydraulic shops will be able to make up new brake lines for reasonable prices if you can't find the correct brake lines from your local MB dealer.

Dean,

Some years ago Peter suggested I replace the soft lines on my diff locks as I could not get the rear one bled through. It was very welcome advice at the time. Now as a matter of course on an old G I replace them all, btakes and diff locks. I think it is worth the money. Something happens inside these lines and they can act like a one way valve and cause all kinds of issues.

I made this gubbin from a garden sprayer so to bleed brakes, clutches, diff locks etc without an assistant. I got the idea off the internet and It works well.

I used to use methalated spirits to wash down brake fluid spills - until I learned from a brakes outfit, water works just as well. Just wash any spilss with lots of water and you will have no issues with damaging paint.

mmmm Andrew now you make me think - I have just had new pipes made up for the diff locks, brakes and fuel lines - I left the rubber ones in place...I suppose while I am busy I may as well do them as well?

OK, thanks.

What went wrong with the clutch?

I have another question: How does one know that the clutch master or slave cylinders need refurbishment/service?
The clutch on my car went soft one day not allowing to engage any gear, stopping and starting the engine somehow solved this although the clutch was still soft. I bled the system through the bleeding bolt on the slave. clutch was still soft but in the morning it was right as ever and is still driving. I did notice that the pin on the master (at pedal) can move a little in a lateral direction (not just up and down the cylinder) is this normal or signs of wear?
