The security and trouble-free movement on the car depend on the impeccable work of clutch. You can drive only if the clutch is operating properly. If the disc is worn or its full adherence to the flywheel isn’t adjusted, there may be the most unexpected situation, until the emergency. Unfortunately, manufacturers do not specify the clutch service life, after which it needs to be changed. It is not done with malice.
The fact is that the normal operation of the clutch will depend on many factors. These are manner of driving, competent operation of the car on the road surfaces of varying quality, the quality of the clutch and many other factors. Clutch may be long and impeccably run at more than 100 thousand kilometers, and can fail after 5-7 thousand. Therefore, the question of self-determination of the quality of the clutch disc is considered one of the most relevant for any driver.
