Your fob needs re syncing, can't just remember how many times you have to press both buttons together, ten i think, stand in front of the car and point the fob at the car, this should sync your fob, Ste

The only thing i can advise is to check the following,
1 Master cylinder push rod is connected and not leaking, there is a return valve built into the cylinder, this could have failed.
2 Slave cylinder, very difficult to check if it's leaking, as if the cylinder is leaking only a every small amount of fluid this will not show under the gearbox, they only show leaking fluid when they have completely failed.
3 When bleeding do-not let any air into the system.
4 Check the union joint for signs of fluid leaks.

If you find any of the above, you will have to replace the part that's faulty, you are using a power bleeder? and not bleeding the system by pumping the pedal, as sometimes this does not work very well, Steve

Are you sure the clutch pedal should be in the up position all the time you are bleeding?

If you leave the clutch pedal in the up position you are not pushing any fluid towards the slave.

The way I would bleed the system is get someone to push the pedal all the way to the bottom and hold it there while I loosen the nipple. And keep repeating the process until all air bubbles are out of the system.

The other way is to reverse bleed by syringing fluid back from the bleed nipple to the master. Make sure that you have a good container to catch the overflow under the master. I've not tried this on a 75 but have done it on several other cars to good effect.

This is how Im planning to bleed mine. Air rises so it just doesn't make sense trying to bleed it from top to bottom. You will never get all the air out or it that way.

It's the bit where it drops through the bell housing that can be difficult for the air to get past. I've heard that a washing up liquid bottle, suitably cleaned out of course, can be used instead of a syringe.

Those clutch judder 'devices' are a nightmare - they either start leaking, or cause biting point issues. They also don't really sort the original problem out!

Not sure what point you are making here.

My point is that air rises, so one is fighting a losing battle trying to push it down through a pipe and out of a bleed nipple.

Better to attach a new oil can full of brake fluid to the bleed nipple and pump the new fluid in, pushing the old fluid up and out the top of the MC.

Pumping fluid up into the system sounds easier & seems to make sense. How many have done it this way?
I'm now noticing that my bite-point has gone down somewhat & the clutch pedal feels a little less reassuring though no problem changing gear as yet. A bleed seems the way to start.

Also, what does this anti-judder device look like & where is it located? I've probably still got one fitted.
