i've got a 1993 nissan 240sx.
my clutch pedal has absolutly no pressure,i've changed the master and the slave cylinder and no go. btw i've removed the damper system and ran a straight steal braided line from the master to slave cylinder.any body got any idea what to do ?my guesses are im bleeding it wrong or im not bleed ing something,for example i think i have to bleed the slave cylinder.
 
The master cylinder is on the firewall, the slave is on the transmission. You have said that you replaced the master and the slave cylinders, well you need to bleed the master cylinder so that it will flow the fluid down to the slave. To bleed the master, Fill the reservoir . then take the hard line off the master cylinder. Place your finger over the port that the hardline went into. Have your buddy pump the clutch pedal slowly, eventually you will make a mess with fluid. Your clutch master is now bled. Now you can have your friend pump the clutch pedal 3-5 times then tell him to hold it down. You will then crack open the bleeder valve on the slave, close the valve and have your friend pump the pedal 3-5 times. Repeat the process until you have pedal feel back. If you have been trying to bleed the slave for more then 7 min. then leave the bleeder valve open on the slave and see if it will gravity bleed on its own. Always remember to keep the fluid Reservoir full, if you let it run dry you have to repeat the entire process.

sometimes if you are exhausted and pissed off, walk away come back 30 mins later and try it again once the air bubbles have moved around.
 
I've done this too many times to count. In all reality you shouldn't have to bleed the master. Just the slave. Have you bleed the system? Until no air comes out? Your system might be fully bleed but your fork might be off the bearing. It happened to me and I swore up and down it was my slave. Changed it twice, blew it twice and then I realized there was too much play with my fork. Just a thought but check up on it.
