My Clutch Pedal Is Loose And There Is No Pressure On It, What Could Be Wrong To My Vehicle?

Could be a broken clutch cable (if you have a clutch cable), fairly easy to fix.

Could be air in the hydraulic clutch system (if that is what you have), might be fixed by bleeding the clutch system.

Could be broken clutch parts like the throw out bearing. Difficult to fix, transmission needs to be removed to get to bad parts.
