We have a 2001 CRD (2.5 diesel, manual transmission) Grand Voyager. We've recently (last 4 months) had the clutch replaced as it was slipping, but suddenly today, whilst out, the clutch won't disengage with the pedal depressed. I believe the clutch on these is hydraulic,could it be a fluid problem ? If so is the master cylinder sealed or accessible to bleed / top up the fluid ? Thank you.
Is there any fluid on the ground near the transmission? It's possible the clutch actuating cylinder has failed. If it was air in the line you would have noticed it the day you got it back. The master cylinder is on the firewall next to the brake master. You can add fluid if it's low. If it's empty then there may be a loose fitting or the bleeder screw on the actuating cylinder may be loose too.

i think youre doing the right thing. they are very stubborn to bleed because the hyd. line goes up high across back of engine before droppiing back down to slave cyl., trapping air. could try to gravity bleed by opening bleeder at slave, cap off of master cyl, full with fluid then it may start to come out after a bit. then try your process again. or can try to bleed at connections further up the line, working your way back to bleeder. hope this helps. be patient.

you have to bleed the air out of it. If there is not fluid leaking from the master cylinder on the firewall.it can leak on the inside of car or the out side if the master cylinder is bad.first make sure the reservoir stays full then open the bleeder on slave cylinder. this is called gravity bleeding. once fluid comes out, tighten bleeder, pump pedal one time loosen bleeder while holding clutch pedal down and then tighten. do this repeatedly until no air comes out. you can pump pedal several times,then hold and bleed however you like but I have better luck with individual pumps. just make sure that the lines hooked to slave cylinder are tight and there are no air leaks. and that the line does not go below the slave cylinder because sometimes air gets trapped in the lowest part of system.

I am a hydraulic technician and I can tell you that air is a killer in the hydraulic system.
Start from the rear and work your way forward. I f you are using the two person method, make sure the second person keeps the master cylinder full. If the fluid level dropped anywhere in between pressing and releasing the brakes....you have a lot of air in the system.
Make sure you are tightening the bleed valve when the brake pedal is full pressed.
Remeber...start from the rear brakes first, then do the front.

Take the top off the master cyl and slowly very slow push in on the clutch and watch for any bubbles comming up.Replace the top and pump pressure and bleed at the master direct by using the lines for bleeders.
