What Causes the Clutch to Suddenly Become Very Light and Unable to Shift Gears?

[JulianaAnn]

Here are the reasons why the clutch becomes light and unable to shift gears: 1. Release bearing failure: Both the release bearing and clutch disc are wear parts. When the vehicle's clutch disc is severely worn, the condition of the release bearing is also likely to be poor. The release bearing is responsible for disconnecting the clutch disc from the friction plate. If the release bearing fails, it can cause the clutch to become light. 2. Clutch cable breakage: The main function of the clutch cable is to transmit the pressure applied by the driver on the clutch pedal to the pressure plate. If the clutch cable breaks, the clutch cannot engage, making it impossible to shift gears. 3. Excessive clutch free play: The clutch travel consists of free play and working travel. The free play is generally lighter, and pressing the pedal during this phase does not cause the clutch disc to move.
