Sheddist might well be right. A few things first, I believe all Freelanders are hydraulic clutches, none have a ratchet adjuster.
A few things check. The 1.8 has an external slave cylinder on the gearbox bell housing, these are prone to breaking the supporting bracket, then the clutch pedal tends to bite low.
The master cylinder is attached to the bulkhead via a quarter of a turn and a has a semi flexible pipe to the master cylinder.
So I would remove the slave cylinder rod from the clutch pedal. This just clips onto the pedal, you get your head under the dash and hold the pedal in one hand and unclip the rod with the other hand. You pull the rod towards the passenger side and it pops off, watch out for the pedal as when you unclip the rod the pedal springs up into your face!!!! Now under the bonet twist the clutch master cylinder through 90 degrees. It should pull out with the rod, now you can reattach the rod retaining clip that should pop inside the master cylinder. Then you can put it all back together. Hopefully that gives you some ideas to fix the problem. Good Luck.
