You mean the master cylinders, you should be able to get a repair kit from MB or try BMG (old Bearing Man) and get the seals from them.

This is what I could find in part numbers........

Mervin at hydraulic solutions refurbished all master and slave cylinders on my G when I rebuilt it.
brake, clutch, diff locs everything. He was able to replace rubbers, boots everything, very reasonable (R1170 in 2012)

Can anyone advise me how to rebuild the two parallel slave cylinders that sits directly under the diff leavers. Mine is in real bad condition
So I got the two master cylinders rebuild. I bled the system and then they both get hard and will not pull up. There is fluid in the slave cylenders. Why would they not pull up?

undo the 4 bolts holding slaves onto axle, remove unit with hydraulic pipes on if you can. Then operate the the levers and see if the pin moves. The force required on the lever is not much , should be easy. Have you replace the rubber hydralic hoses ? On a W460 this should be done immediately if never been done before

Thanks for the response. I have not replaced the rubber hoses, I did clean up some of them that I found was blocked. I will check them all. I will remove the slaves today and check thanks!!

The rubber collapses from the inside preventing fluid flow back especially in the reverse direction as this is driven only by a small spring in the locker actuator. The locker never properly disengages resulting in damaged teeth , which damages bearings and crownwheel and pinion . Seen it happen myself. Don;t scrimp with the rubber hoses

I removed the slaves. It was totaly seezed up. I am cleaning now. The part in the diff seems to be moving freely. Please look on my FB page for photos. Hope I am not stepping on toes, this forum is just to outdated to communicate on. https://m.facebook.com/Geländewagen-South-Africa-1584027768363046/

I cleaned out all the pipes and cleaned out the slave cylinder. It was rusted and seized up. After putting it back together I tested it before mounting to the diff, but still having the same problem. It is not moving. I can move the cylinder pin with my hand but not with hydrolocks. Any advise please.
