Failure is manifested in that the crankshaft does not disengages the transmission from trying to change the speed and is accompanied by a loud noise, especially when trying coupling speed first, and due to the existence of a race free too high a clutch pedal; mounting springs too hard, dirty and stuck gasket of lining; deformation clutch disc ; deregulation and tear of clutch levers; Clutch cable breakage; the existence of broken pipe; leaks from hydraulic control pump or central cylinder clutch.
The clutch does not trip due to the existence of a race free too big Pedal
Defects caused by incorrect adjustment, the high wear of the joint mechanism to control or regulate the rod connecting the pedal, make it impossible to depress completely and is accompanied by the noise of gears that cannot engage correctly, the sides of their teeth wear themselves.
Mounting springs too hard
Failure, besides not allowing declutching complete clutch, can have serious consequences such as breaking crankshaft or some parts of the transmission, especially when braking suddenly without the clutch or when instantly switch from position slippage at the strong adhesion (of ice on solid ground).
Disengages the clutch is not due to deformation clutch disc
Failure leads to the impossibility of decoupling clutch. Pressure to remove plaque, warped surfaces will achieve both its surface, and on the flywheel, remaining in contact, which will make the move from the engine to be transmitted faster.
Failure occurs, in most cases, due to overheating, the reconditioning defective mounting and improper handling or storage.
Deregulation of clutch levers
Failure action makes the bearing pressure on the clutch levers no longer be uniform, because their heads are not in the same plane (between their plans to create a greater distance of 0.2-0.3 mm). Because of this pressure plate will not move parallel to the initial plan but tilted so that one side will release the clutch disc, and the other will remain in contact with it. As a result, disengagement is not done completely, the engine remains in contact with the rest of the transmission. In an attempt to shift the noise of gears.
Failure is accompanied, especially early depressing, by an uneven metallic sound and a slight tremor.
The clutch disengages no clutch lever breakage due to defect track has similar deregulation of clutch levers, but being accompanied by a permanent friction noise produced by hitting the lever broken continue rotating discs or other levers. Failure can lead to rupture all or clutch levers.
Disengages the clutch is not due to faults hydraulic control mechanism
Damage can occur at pipes (broken or leaky), the central pump and clutch cylinder that may be leaking or may occur due to lack of liquid.
Damages lead to a condition could not be complete disengagement clutch. Similarly gasket failure is manifested piston pump, which allows leakage along the piston, instead of being sent to the cylinder. The existence of air in the system causes a similar malfunction.
