ok, heres the deal, my clutch system was loosing pressure somewhere and it would cause my clutch to not disengage or engage properly, causing me to grind gears.  so i saw some fluid leaking from the slave cylinder, so i got a new one.  well, i changed it, and now i cant get any pedal pressure.  ive bled it over and over, the pedal just sticks to the floor.  what gives?!

just manually bring the pedal back up and pump it till you feel a firm pedal.

also bleed the dampner its off on the side and it comes before the slave

welcome to the wonderful world of trying to bleed a 240 clutch. every nissan tech will tell you they are annoying and hate them.

and they are. first start with bleeding the dampner. have someone pump your clutch pedal several times then hold it while you loosen the bleeder screw. redo that a few times then move to the slave cylinder and repeat the process for the slave a few times. and then see how it is.

also check for the bushing that goes on your clutch pedal if its not in there it will cause gear grind and not let you disengage the clutch correctly. that is very overlooked and can be a problem that wontt even be thought of

I know your pain,

I just changed those components last week,
I went through 8 bottles of brake fluid trying to get pressure.
Eventually it will work.
Be patient, you will be happy with the result.
