2008 Clutch - master cylinder replaced, biting now very low
Hi,

Something in the clutch system on my 2008 Defender failed. No sign of clutch fluid leakage but pedal went to the floor. Managed to get it home. Mechanic advised pumping the clutch when driving and we could get it to his workshop. That seemed to get us there but it would still stick to the floor, but we did it.

He replaced the master cylinder and left it with a piece of wood jammed down on the pedal to see if it was leaking. Seemed to be ok.

However, the biting point is now very low and there isn't much resistance until it reaches a few centimetres from the floor.

I've only driven it about 10 - 15 miles since then but it doesn't seem right. He says there's no adjustment and that given time and miles, it will sort itself out, and that there might be air in the system. Sounds odd to me that there could be air in it that could escape and that it won't come back in.

Is there a way to adjust and could it be that all is ok and it will just take time to bed in, with the clutch returning to how it was before?

Thanks,

Steve 2008 Defender 110

Sounds like pedal height needs adjusting. Two nuts adjust position of pedal arm on the mc rod. Cheers

Mine failed at 106,000km.
2014 model. There is an updated parts list on the Clutchfix site.
I think you will find that it is the slave cylinder that has failed which means a gearbox out job.

Ok, thanks both for that.

I'll see if he can adjust the pedal and give it a go with the master cylinder as that work is done, but it's in the back of my mind if could be the slave cylinder which is a pretty big job... 2008 Defender 110

Try the easiest first.
Get rid of the air first and check for any improvement, use only a genuine replacement.
Not so easy to adjust the stroke when in situ,
Though have the very same issue some time ago, pedal on the floor, looked for any leaks, while hoping it wasn’t the concentric slave cylinder.
Swapped out the old MC, removed the complete pedal box assembly, on doing so bored a socket size hole on the outer pedal box, giving access to readjust the push rod on the cylinder if required.
