I've had the dreaded clutch pedal drop with no obvious leaks of fluid.

I've changed the master cylinder and managed to get the pedal back I then left car I've night and then the pedal gets stuck half way and sometimes down to the floor again. I've re bleed the system twice na drive it about straight after and it drives fine leave it again for half hour and then back to square 1.

Anybody got any ideas or suggestions

Thanks 

Did you pressure bleed it?

Yeah put pressure on pumped the clutch 10+ times clutch to the floor and open valve and then closed as soon as we got consistent fluids and repeated 2+plus times

 

Let me rephrase the question, did you use a pressure bleeder?

Yeah mate 

I wouldn't bother depressing the pedal, just pressurise the reservoir then open the bleed nipple until you get a good flow then close nipple, depressurise reservoir and test pedal.

I will try that tomorrow if not looks like it's off garage 

Air is being drawn in via the O ring that joins the two plastic moulded sections of the concentric slave cylinder, gearbox out job. Cost of parts 1 pence but most of us would replace the cylinder, clutch and DMF at the same time.

 

Now I know you havn't said whether you have a concentric slave cylinder or an external one but I am right aren't I!!!!

 

Bleeding will gain you some reprieve but it will get worse and worse, I was having to bleed mine every few miles unless I was on a motorway and not changing gears.

 

These vehicles dont need pressure bleeding on the clutch, just simply attach a clear vertical tube to the bleed thumbturn and open it 180° the air will come straight out with a tiny bit of fluid, its sits there in a pocket designed for that very reason, it is coming in downstream and downhill of it and does not rise any further up the system, pumping or pressure bleeding is more likely to dislodge the air and push it into the cylinder
