the fluid is like all the way down in the bottle just like 1 inch above the master cylinder. where is the most common place for leak to occur. and will a worn clutch cause this. someone who knows please tell me.

 

most likely master or slave

 

Check the rubber hose, going to the metal line. Check the clutch master cylinder, if its leaking, a majority of the time it'll leak inside of your car. If you have a worn out clutch, it could also cause low fluid because it is using the fluid more to compensate for loss of pressure/clamping force. Kinda the same way with brakes.

Check the line going to the slave cylinder, it should be an easy leak to find if it is leaking. Only a few places it can leak from.
