I've had this same problem for a solid week. When I go to push on the clutch pedal on my 2000 V6 5-speed, the pedal goes all the way to the floor with no pressure and the clutch will not disengage at all. Had a slave cylinder leak, so I replaced the slave cylinder, no more leak, but still no pressure at all. The system has also been bled in excess of 9 times to the point where no air is left in the system. I still have breaks, so the master cylinder seems to be fine. Somebody please help. This is my only car and I'm stuck with no way to work.

 

Your clutch and brakes don't have anything to do with each other, they each have their own master cylinder.
Since replacing the slave cylinder didn't help, the clutch master cylinder would then be the likely suspect.

 

if the clutch master cylinder is bad, wouldn't there be fluid in the floor of the car?

 

Nope, they can leak internally, past the seals, which makes it lose the ability to build pressure.
That's a pretty common thing when a master goes bad, clutch or brake.

 

Any idea on where the master cylinder is located?

 

Ok, so I can build a little pressure, but not enough to actually disengage the clutch. Haven't changed the master cylinder yet, but, since it will actually build a slight bit of pressure, I wouldn't think it would be the master cylinder.

 

Well, pretty sure my clutch works, but hasn't bled correctly yet. Apparently, it takes a couple of days to bleed itself.

 

A bad master cylinder can build up some pressure, but not be able to hold under a load, like what's needed to disengage a clutch. Don't be so fast to count it out.

 

Got it done. Had to hook up a pump and pump fluid backwards through the system in order to get all the air out. The master cylinder is ok it just didn't want to bleed.

 

Yea they are pain especially without a pump last me and bud took turn bleeding a clutch on civic for like a solid 20 mins
