I have a 93SE with clutch issues. When I start the car the pedal has very little pressure but after about 15 minutes the thing feels okay. I think I have a bad slave cylinder cause the boots got fluid in it but why would it have more pressure after warming up?

 

Air in the lines... ?

 

i agree with nismo1989 with air in da lines. or double check for fluid

 

if the boot has fluid in it, that means the seals are leaking.. replace the slave cylinder and your problems should go away.

 

I swapped out the slave cylinder and the clutch feels great. Thanks for your help. Its working so well I may have to wait for the 2005 now.

 

It has more pressure because as Matt said the seals are bad. Rubber expands when it warms up sealing the leaks and giving you more pedal pressure.
