Releasing the cable end from the clutch pedal is a bit awkward, but it just needs the right knack.
Disconnect the cable from the clutch release arm on the gearbox.
Remove the under-dash panel and look up and you can see the white plastic connector piece.
With the pedal in the relaxed position reach up and push the plastic connector off the top of the clutch pedal hook against the plastic guide pressure, then press the pedal down.
The plastic connector will now be disconnected, so go to the engine bay and reach round to the cable bell crank unit and pull/pry it towards the front of the car, to pull the upper cable out of the guide.
Your car doesn't have Egr fitted, so there should be enough space to wiggle the cable out from the back of the engine pretty readily.
When installing the new cable ensure the clutch pedal is in the upper position, then route the lower cable round the back of the engine and into the cable ring, post the upper cable into the guide and keep pushing in until the plastic connector clips onto the clutch pedal, then fit the other end to the clutch release arm.
It was designed to be fitted in a few seconds on the assembly line, so the plastic guide directs and clips the upper connector to the pedal just by pushing the cable in.
If you struggle to gain enough slack to be able to fit the lower cable to the release arm, reach round the intake manifold with a screwdriver and press the lower cable into the sheathing by pushing on the round collar.
This will release the locking collet so allow the lower cable to be pulled out of the sheath more, against the spring pressure.
Under no circumstances throw away the bell crank unit, they were only ever made for Rhd Xm and Peugeot 605 and are not available anywhere.
Cables and the actual bell crank can be repaired/remade.
The difference between a cable for 2.0 petrol Xm with Be3 gearbox and all others with Me5T gearbox is the length of the lower cable.
As said, the regulator sphere provided a reserve of pressure for the main, high pressure hydraulic circuit, which is where the front brakes are fed from, the rear brakes are fed from the rear suspension, so until the rear of the car is riding on the bump stops there is rear brake pressure.
Citroen hydraulic systems are really simple, so don't be nervous of them.

Citroen built the car and recorded it as a manual transmission.
), no idea if the hinges broke.
