Clutch Kit: Why Is My Clutch Stiff?

The clutch of a car is what makes a manual transmission function. The clutch gets compressed so that the driver can change gears thus increasing speed. Sometimes the clutch will have problems that could cause it to be stiff.

Stiffness of the clutch can be uncomfortable whilst driving because the harder it is to press down on it, the more strength you would need. Here are some of the reasons why the clutch is stiff:

  • Damaged clutch cable: this cable needs to have maximum amount of tension for the push and pull motion. This cable is made from steel so that it will last for long periods of time. It assists with the process of changing gears by extending to disengage the clutch.
  • Damaged master clutch cylinders: usually when a master cylinder is damaged it will leak. Leakage in the master cylinder releases liquid which means that it can no longer build the right amount of pressure.
  • Air bubble in the hydraulic line: the hydraulic system can’t have any air present because the system works with liquids such as oil, brake fluid and clutch fluid. This line assists with the transportation of the hydraulics to the different components.
  • Misadjusted clutch linkage: Because the system works with very small tolerances, an error such as a misadjusted clutch linkage could be detrimental to your driving experience. A specific amount of force has to be used when applying the different pedals. It is this linkage which controls that force.
  • Incorrect Components: not all clutch parts are compatible with the factory clutch kit already installed in your car. Compatible parts are important in a car’s structure. Some systems will use different applications.
  • Another problem that could cause a stiff or hard clutch is a worn throw out bearing, or clutch release bearing. This component applies pressure to the fingers of the pressure plate to allow the release of the clutch whilst spinning. You can easily detect this problem with a low rolling-like sound as well as the stiffness of the clutch pedal.

A problem such as this should be checked and fixed immediately. This type of problem can go on for years and many people only react to it once it dramatically affects their driving. This could become a dangerous game especially if you do not know what the problem is with your car and you don’t have a mechanic nearby. A manual transmission car will not be able to function without a properly installed clutch kit.
