what happens when that happens??

 

got leaks?
is there still fluid in the slave cylinder?

 

you may have a leak in the clutch lines or a bubble as well.

bleed your clutch lines to remove any bubbles and clean all exterior clutch line parts
including the clutch master cylinder. then check for leaks

 

replace slave cylinder

 

this happened to me in my z24. my slave cylinder was broken.

 

not to threadjack the OP's question but i have a 93 ej2 and whenever i depress the clutch, it kinda squeaks a little bit, and it didn't do that before until winter of last year when it started to get colder.

any info?

 

spray WD-40 on the clutch pedeal assembly?
