1. Low Clutch Fluid - No, we're not jerking your chain; clutch fluid exists. Additionally, the fluid level in the clutch fluid reservoir ought to remain constant. If not, you have an issue with the system, and the clutch master cylinder leak is most likely to blame. Check MOT history to confirm if a clutch problem was a reason for a MOT test failure for your car in the past.The brake fluid is used by the clutch master cylinder in many car types; hence a common reservoir is utilised by both devices. It is therefore likely to utilise brake fluid if you can't locate the clutch fluid reservoir.
2. Soft or Spongy Clutch Pedal - Similar to brake fluid, if your clutch fluid feels soft or spongy, you likely have air or water in the system. There is no reason why moisture should ever exist in clutch fluid because it is fatal to have moisture in a hydraulic system. Therefore, if your clutch pedal is mushy or spongy, the system has a leak. The clutch master cylinder is one of the most likely offenders. To prevent a potential MOT test failure, check MOT status and have your mechanic fix this problem.
3. Your Clutch Engages at a Different Position - It's conceivable that your clutch will engage at a different point if the level of your clutch fluid has reduced significantly. It usually has the effect of requiring you to fully depress the clutch pedal in order to release the clutch, which is usually much further than your regular engagement point.Not only can it alter the interaction point, but it can do it quickly as well.

4. Dark Clutch Fluid After Changing It: If your car has more than 100,000 or 200,000 miles on it and you notice that the clutch fluid is a little dark, this is completely normal. Clutch fluid will wear out and degrade with time. Flushing the fluid will allow you to determine if your issue is resolved. However, if you check your fluid a few thousand miles after changing it and it has already darkened, this is a sign of a more serious issue. Usually, when the clutch master cylinder breaks down, it's the gasket and seals. Your clutch master cylinder may be leaking in addition to the issue these pollutants are causing.
5. It's Difficult to Depress the Clutch - The clutch master cylinder's sole function is to assist you in disengaging the clutch. It follows that pressing the clutch will become more difficult if your master clutch cylinder is leaking. In fact, you won't be able to release the clutch at all if the leak is severe enough.
6. Clutch Pedal Stuck to the Floor - If you discover that your clutch pedal is stuck to the floor, your clutch system's hydraulics have failed. A significant leak in your clutch master cylinder is the most likely culprit. You'll need to make repairs right away if this occurs because a stuck clutch pedal will prevent you from changing gears.
Workings of the Clutch Master Cylinder
In order to assist you in disengaging your clutch, your car sends clutch fluid through the clutch master cylinder. When you compress the clutch pedal, a pushrod on one end of the cylinder pushes against the clutch fluid, moving it to the slave cylinder and ultimately to the transmission's clutch fork.
The force you apply while depressing the clutch pedal is transferred to the transmission by the clutch master cylinder.
Location of the Clutch Master Cylinder
In the engine bay, your clutch master cylinder is normally placed in front of the clutch pedal but on the opposite side of the firewall. It is frequently seen nearby the brake master cylinder.
If you draw a straight line from your clutch pedal into your engine bay, you'll typically discover the clutch master cylinder because it normally links directly to the clutch pedal via a pushrod.
