i have a 94 civic lx 1.5.... clutch bearing was squealing for about 2 weeks then clutch pedal at start up went to the floor and stayed there...is this a master cylinder problem or slave clutch problem , or could the clutch itself went out... i need to know how big a problem may need fixed...any help thanks..

 

Check whether clutch release fork is broken. It also could be that pressure plate is toast.

 

Could also be a leak in either the master or the slave. See if you have any fluid on the slave, on the firewall or around the clutch pedal.
