To help you understand, we will start by telling you what is a clutch for et how does it work .

What is a clutch for Citroen C4 Cactus for?

The clutch of your Citroen C4 Cactus is an important element because it will connect the engine with the wheels. So it will transmit the engine rotations to the wheels of your car via the gearbox depending on the gears engaged.

How does the clutch work on Citroen C4 Cactus?

In this way, in order to allow the driver to change gear, the function of the clutch is to disconnect the engine from the gearbox. Therefore when the driver press the pedal this will dissociate the two parts and it can switch to another speed. When the driver releases the pedal, the clutch will return to full stop with the flywheel and will transfer the rotations to the gearbox. The latter will rotate the drive shaft at the selected speed and the rotations will reach the wheels. If you want more information on the gearbox, do not hesitate to consult the article below: hard to shift speed Citroen C4 Cactus.

Understand why the clutch slips on Citroen C4 Cactus:

Now that you understand what it is for and how it works, we can more simply tell you why your clutch is slipping.

You will understand that the clutch must be in abutment with the flywheel to transmit the rotations. However, to do this, the clutch turns out to be a rather complex mechanism, equipped with a number of elements which over time can wear out. For example in your situation, it is possible that friction materials which will allow the grip between the engine flywheel and the clutch disc to be worn and that this decreases the contact between the two components and therefore reduce the energy transmission.

Another possibility is a problem with the diaphragm spring. Indeed to allow the clutch to separate from the flywheel, there is a part called diaphragm spring. The latter will press the clutch disc on the flywheel. And on the contrary when you press on the clutch pedal it will release the pressure in order to separate them and allow the gear change. When the spring is worn out, it often happens that the pressure on the clutch disc can no longer be properly and therefore the contact is no longer sufficient and you will skate.
