Symptoms: Pedal sticks to the floor and is very soft.
Replaced: Both the clutch master and slave cylinders and bled the system.
Problem: Pedal is still very soft and sticks to the floor still.
Anyone have any idea of what this may be and how to remedy? Please help. Thanks in advance.What is wrong with my clutch system on my 1993 Nissan Maxima?Make certain you have gotten absolutely all the air out of the lines. Run an additional half pint of fluid through the system, just to be sure. Check the caps on both cylinders and make sure they are on tight with seals in place. Make sure the bleeder fitting is tightened. Hopefully you checked the line for leaks while you were replacing things, otherwise replace the line with a SS braided line (about $30).
If there's still a problem, check the linkage from the hydraulic system to the clutch pressure plate. Likely that something has come loose there.What is wrong with my clutch system on my 1993 Nissan Maxima?There is another bleeder look by the left fender follow the piping to the slave cyl. That larger pipe takes up noise in larger tubing and some times people forget to bleed the damper hose. Rapid pushes of the clutch and pulling the clutch pedal back up with your toe is necessary to get all the air out. I use a hose sumerged in brake fluid so air does not travel back when I pull the pedal up off of the floor. Do not adjust the master Cyl push rod many more problems are caused by mis adjustment there.What is wrong with my clutch system on my 1993 Nissan Maxima?It sure sounds like you were on the right track (clutch hydraulic problem).Did it change any at all when you replaced those components? I suspect it did...if so there may be air in lines (need to re-bleed).If it did NOT change anything (replacing those parts)...congratulations for you have stumped me (if you've read any of my other answers then you'll know I usually have an opinion %26amp; correct ALOT)
