All 4 of my front slave cylinders are leaking and in need of replace, the new ones are ordered for tomorrow so i thought I would use this time to educate my self about bleeding them. Any tips or advise?:confused:
 
Start at the one nearest to the master cylinder and work outwards from there i.e. OSF, NSF, OSR NSR.

If you have a servo fitted you need to run your engine whilst bleeding.

Hope this helps.
 
That's half a day so far bleeding the brakes, hopefully if I leave it overnight it might fix its self ha ha. Was suppose to be back at work by now! oohh joyys!!! I started as you said going roung in that order 2 or 3 times then let them gravity for a while but the pedal go herd when pumped and then goes soft after a few seconds. I hope its air in the system and not more new parts :confused2::confused2:

Conventional wisdom says you should start at the wheel furthest from the master cylinder, I don't know if there is anything different with the OP's vehicle but I've never had an issue with any Landy when bleeding brakes. Oh and the servo has no effect on the process of bleeding brakes on any system I've ever come across other than a couple of Porsche models which have a pump rather than a servo?
 
problem is usually on the front, took me ages to get mine right. the trick i use now it remover the wheels, brake drum, hub units, and then undo the six bolts on the back that hold the backing plate to the stub axle, and turn it upside down so the bleed nipples face upward, this stops air getting stuck in the wheel cylinders and makes it much easier to bleed.
remeber when you do this though to put the drums back on and do the addjusters up against the drums if you are not using a, air compressor style hydraulic bleeder, if you have acess to a hydraulic bleeder, squeeze the shoes as far into the wheel cylinders as they will go so you have less place for air to get stuck
