You've lost all pressure on the clutch cylinder.
I can't tell you if it is the master cylinder, or the slave cylinder, or just that you have a slow leak and ran too low on fluid without being there to see it.
Check the fluid level, if it's low or out refill it, then pump the clutch by hand in and out and check to see if the fluid is running out anywhere, the hose between the two cylinders may also be damaged, but you'll have to find that leak to be sure.
If no leaks are found then it is probably a slow leak, you can bleed the system and get by for a little while but replacing the leaking part will need to happen soon, it is most likely the slave cylinder though, they go bad much more often than the master cylinders.
replace the bushing where the clutch pedal attaches to the master cylinder arm.
No.The clutch is hydraulic and not adjustable.
Well, we need lots more information here. Is the clutch pedal actually "stuck" to the floor? In other words, can you NOT lift the pedal up to the normal position? OR, has the clutch pedal "fallen" to the floor due to no resistance from the clutch?
if its hydraulic there could be air in your line. bleed your clutch and refill.
It's called: Your clutch is working.
If the pedal just randomly falls to the floor, you probably have a broken pedal or linkage. If we are talking about it having no resistance when you press it and the clutch not disengaging, you probably have a leak in your clutch hydraulics. This can be a bad master or slave cylinder, or a leaky line. Bleed the clutch, and then keep checking the fluid daily to see if you are losing it.
you might have a air in your clutch system or your clutch master/or slave could be worn.
Usually at the upper end of the clutch pedal under dash
