Clutch problem
 

Classic pedal to floor replaced master replaced slave pressure bleed .This is the forth time back to fix my soft clutch pedal .Replaced clutch pedal spring ,Now replacing the lines starting at the slave. Mechanic thinks it is possible my 8 month clutch is weak and not pushing slave. Pretty sure its a closed system ,push pedal fluid pushes slave, let off clutch pedal the fluid returns to the space in the master . What do you think?
