afternoon everybody.

I am sure this has been covered before so please accept my apologies for going over old ground.
It's been a month since anything has gone wrong with the freelander so I was kinda expecting something
To happen.

The plastic linkage from the clutch pedal to the master cylinder broke. No problem. So I fitted a new sealed system comprising master cylinder, slave cylinder and pipework.

I had no fluid leaks and the plastic clips that hold the slave cylinder piston back both stayed in position.

Started the car and was not able to get it into any gear. With the wife operating the pedal I can see that
The slave piston is pushing on and moving the lever on the gearbox. However the amount of distance the
Slave piston travels seems very small. Maybe an inch?

Does this sound like air has got into the system. The lever on the gearbox is moving so has not seized up and the gearbox/clutch was fine until the plastic linkage broke.

Any thoughts........thank you.
 
There's air in the system. I find that the air needs expelling before the assembly is fitted. It's a case of holding the master up with the slave hanging below. Keep the reservoir in it's normal fitted position. While held like this. Press the slave plunger fully into the cylinder. Release it and repeat this action a few times. This will force any air up into the master reservoir and replace it with fluid, curing the problem.
 
I'd also be inclined to question the freedom of movement in the release arm. These are notorious for siezing up - which may explain why something broke originally - although usually its the bracket the slave clips to that fractures. I think its always prudent to change that bracket when renewing the hydraulics, and I'd be lubricating the release arm where it goes through the bell housing.
 
Is it worth buying another new master, slave and pipework kit and carrying out the air bleeding techniques you suggest before fitting.

Or do you think the existing slave and master cylinder can still be used.

How does air get into a sealed system?
 
Yes I left the plastic clip on the slave until everything was sorted and then cut the two arms on the clip.

The bracket that the slave mounts on is in good condition. Hardly any rust, not bent or fractured.

Took the slave off today and keeping it lower than the master pumped the piston without letting it come out too
Far. Hoped this might dislodge any air but no improvement.

The lever on the bell housing has movement and you can hear something operating inside when you
Move the lever by hand but I am wondering if the amount of movement is actually enough. I have sprayed everything with plus gas and operated the lever by hand for quite some time to see if would free up any more but it
Doesn't.

If the lever was a hand on a clock face, you can only move it between the 12 and 1 o'clock positions.
12 o'clock is when it's the furthest back against the bell housing and 1 o'clock is the furthest it moves towards
The slave cylinder bracket. Does that seem about right?

I have ordered another master,slave,pipe kit and will give it another go. Wondering if I dislodged something in the slave and allowed air in as I was feeding the thing into position around the engine bay.
 
You won't be able to push the clutch lever by hand but so long as it isn't seized and you've lubricated it well then it should be ok. I've heard some of the cheap aftermarket master slave units can give trouble.
