Often common causes of this unpleasant phenomenon – a violation of the freewheel clutch pedal, oiling friction linings in the mechanism, wear of the pressure springs or malfunction in the hydraulic drive off.To eliminate slipping in the first place measure pedal free play clutch. It provides a mechanism with the slip. The measured value is compared with the state of the instructions to the car. Where there are differences, adjust in accordance with the recommendations set forth in the same statement.If pedal free play is correct, check samblanet friction linings. With high probability this may occur because of the increased level of oil in the transmission or clogging the drainage holes of the flywheel, and also because of the sloppy grease thrust bearing input shaft of the gearbox. Oily pads wash with gasoline (kerosene), wipe dry and smooth with fine sandpaper. Oily drive change together with the friction linings and eliminate cause of oiling.When wear of the friction linings of the driven disc of the clutch can also slip, as the free play of the clutch pedal decreases. With a small lining wear adjust free play at significant – replace drive plate with worn linings. Also friction linings subject to mandatory replacement at detection of cracks on their surfaces, uneven wear and burning.Loss of elasticity of the pressure springs is a natural process, manifested as a result of their long work. However, they do not create enough pressure on the clutch disc and the clutch starts to slip. To check the status of these springs require special tools and devices, so it is recommended to do it in the service center.Another reason for the slipping clutch may be swelling of rubber parts or clogged compensation holes in the hydraulic drive him off. These items can be: rubber sealing rings and rubber o-ring floating valve piston of the master cylinder rubber seal master cylinder. Causes of swelling is the use of substandard or inadequate brake fluid, and getting in it gasoline, kerosene or mineral oil.
