Just replaced the servo and master cylinder after loss of pedal and 'pumping up'. Assumed master cylinder fault as no leaks anywhere. Straightforward job, apart from finding engine oil in the servo. I assume that was a legacy from the recall when the new suction pipework and vacuum pump were fitted as the original set-up pulled oil into the servo, I've been told, but the dealer didn't check the servo. It was still holding it's vacuum. There was no oil in the servo suction pipework and it was definitely engine oil. (It's a 2005 D3 with 46k on the clock.) The end of the master cylinder where it fitted in the servo was bone dry.
Anyway, I've bled it twice using new brake fluid and an Easibleed at 15psi, very little air came out, just a few bubbles. There's new fluid at every caliper, still no pedal to speak of. I believe there's air in the system still as I can't think of any other explanation, but how do I shift it? More or less pressure in the Easibleed?

According to the workshop manual - if air is introduced to components at the 'upstream' servo/master/cylinder/ABS module end of the system (as you would inevitably do when changing parts) then the dealer software tool has to be used to set something (valves?) before bleeding is done. Don't know if other tools can do it but no doubt one of the experts will be along in a mo to tell you.
Thanks for that. I have the workshop manusl on CD and thr bleeding procedure was routine. Also, I did a search in the maintenance section before I posted and a guy had done the same job with no bleeding problems... so a bit confused now and will seek more advice. Food for thought and if you're right more than a bit awkward. Later....
Just bled it twice more the old way. Got some more air out but no better. Pedal pumps up but then slowly floors, exactly as it did before the new servo and m.cylinder, which to me points to some other fault but no leaks obvious. Can a caliper leak inside? Very perplexed. About to call stealer re your suggestion..Make the most of this life, you may not have a Landy or skis in the next one.

Does the pedal cteep to the floor with the engine on or off?
If the latter, then it's perfectly normal, as long as the brakes work when driving My D3 Build Thread
Pedal creeps to floor with engine running with foot on it and is virtually solid with engine off. Stealer just checked the chassis number and said no T4 needed to bleed. Also said that the pedal will go down, but surely not all the way....?Make the most of this life, you may not have a Landy or skis in the next one.

Have you tried bleeding without the eezibleed ie, the 2 person method with someone opening the bleed nipple for the down stroke and then closing it when pedal on floor and for up strokes? Worth a try, but having said that I had no problem using eezibleed on my 55 plate when I replaced servo etc and fitted the extra vac pipe .
I have to say, the pedal on mine has always been solid with eng running , no creep at all, and even harder like it should be with eng off and vac depleted.

If the pedal is solid with the engine off, there is no air in the system
The pedal creeping down with the engine on is perfectly normal, and was covered in a previous thread not too long ago My D3 Build Thread
Thanks guys.. I wasn't happy with how fast the pedal went down and was fairly certain there was still air in the system. We had bled it 5 times, 3 times with the Eezibleed and twice with my wife 'on the pedal' to no avail. Over a cup of tea, SWMBO asked if there would be more oomph to her 'pedalling' if the engine was running.. I'd never known it done so we tried it and got air at every wheel! The pedal is better and we'll give it another go after supper as there's still some room for improvement.. Be seeing you for a service soon Mikey, once I'm happy with the caravan on the back.

Too late now but you should have taken it back to a LR dealer to have it fixed as they shouls have changed the servo if it had oil in it when they did the recall mod to the pipes.

Thanks for the replies. I can't take the Disco back to the garage where the recall was done as it has inadequate brakes, I don't know which garage did it and it was no doubt done a few years back & I bought it in Brum and I am near Inverness! I thought I'd fixed it, went to use it 2 days ago and had a soft pedal... We did 3 Eezibleeds, three proper 2 person bleeds and now I'm almosr past caring. I can only assume that neither the servo nor m/cylinder were faulty and that there's another issue such as a leak. It' s so difficult looking at the pipework underneath when one only has axle stands or ramps. I checked with my nearest LR stealer who took the chassis number and it doesn't need bleeding using T4. .Make the most of this life, you may not have a Landy or skis in the next one.

Says this for both 'standard' and 'high performance' brakes. Maybe it is VIN# specific but difficult to be sure.
Hope you get it sorted. I once had similar problem with a Jeep and turned out air was getting in through the threads on the bleed nipples. Fixed it using plumber's PTFE tape but being very careful not to allow tape to get on to the nipple where it butts up to caliper to form the seal.
ThanksPaddi. We had another go yesterday and using witchcraft to find which pipework was holding air and an unusual bleeding method we did it...we determined it was the front left corner using the witchcraft (Applied Kinesiology for the curious) which I won't elaborate on here my wife on the pedal and me at the bleed nipple with a large plastic veterinary syringe attached to plastic tubing on the nipple, the wife slowly pressed the pedal whilst I 'sucked' with the syringe. We also had the engine running. It worked and a load of bubbles came out. After 8 previous full bleeds I was very relieved.. This was my wife's idea from some years back when I couldn't bleed the clutch on a 90 (the pipe goes up from the m/cylinder, along the bulkhead and down, making a great air trap. I wan't able to read your link as due to the phone company cutting the phone line off 2 weeks too early prior to a house move, I only have my phone for broadband and reception is poor here (hilly). Thanks to all repliers. Ed.Make the most of this life, you may not have a Landy or skis in the next one.
