Petal fur clutch has no pressure

 

Check the fluid level at the master cylinder. If it is empty, check for fluid at the push rod between the clutch pedal and the master cylinder. If there is fluid there, replace the master cylinder. If there is no fluid there, the slave cylinder is probably bad. If the fluid reservoir is full, the master cylinder is probably bad. There is also the possibility that the linkage between the pedal and the master cylinder or between the slave cylinder is broken or otherwise disconnected.
