Clutch Trouble NO Pressure HEEEEEEEEEELLLLLPPP...

[Spanky37]

Okay so im driving (1993 240sx hatch) and my clutch pedal was already loose. but then it just sunk to the floor and i couldnt put my car into gear. i can start my car beacsue of how the switches are or w/e. so i was told that it could be a bad master cyl. so i just replaced it ran dot 3 fluid through it before connecting the hardline made sure there was pressure. connected the hardline then bled it from the slave. wasnt really any air bubbles. and there is no dampener hardline connects straight to the slave. so bled it for about 10 20 minutes and the pressure wont build up. could it be my slave or am i looking at somehtin bigger?.

just replaced the slave cyl. today and ive bled it for about 30 minutes.. still barely any pressure.. the pedal will barely come back up on its own.. and if held to the ground while bleeding it . the pedal wont come back up.

Check the pedal assembly. The spring or another part of it may have broken.

bleeding should only take seconds, crack the bleeder and pump the clutch a few time, close the bleeder ur done.

Same s*** happened to me. check both sides of the clutch master cyl. to see if the rubber gromet is leaking. mine had a slow leak into my cab. part cost 26.99 at advanced auto and auto zone. try that after you bleed. slave cyl cost 14.99 at advanced if you replace the master replace the slave. total down time is maybe an hour if your working in an appartment parking lot with a scissor jack. takes a 10mm on all the bolts including the bleeder valve on the slave. you'll need a 3" extension and a socket or a swivel head gear wrench to take off the master. but its no biggy.

yeah i didnt even check it i just replaced it and the slave but still with bleeding it the pressure wont build up. im gonna go back through it tonight and tighten everything. after i bleed it the clutch looses the very little pressure it built up.

Does your car have that dampener block for the clutch? If so just take that pos off its worthless. I had the same problem with my bros coupe. Its right next to the frame rail and has a looped line on it. The block has a bleeder on it but I couldnt get it bled. I just hooked the clutch line directly to the slave cylinder.

[Spanky37]

Nah my hardline goes straight form the master to the slave. but its possible i didnt tighten the line enough and could be leaking a bit. gonna check that first. then try and bleed it again.. does it make a difference if you use a hose on the bleeder bolt or just loosen it and let the fluid squirt?

[Ni$$@n240]

Its better to use a hose on the bleeder that goes into a bottle. When using a clear hose you can see the air bubbles coming out if its not bled all the way. The best thing to get is a pressure bleeder that bleeds it from the bottom up.

[Ni$$@n240]

When you said that you ran dot3 through the clutch master cylinder how did you do that? You should have had some sort of replacement fitting where the clutch line threads into with a hose going back into the resivoior. Otherwise you will just suck air back into the master cylinder when bench bleeding it. If thats the case you might go through more brake fluid than anticipated to bleed it all the way from the master to the slave.

[Spanky37]

what i meant is when i first put the new master on and before i connected the hard line i pumped the clutch til the fluid was coming out of the master where the hardline connects . then i connected it and pumped the fluid through the line into the slave and bled it through the bleeder valve not using a hose or anything. by the way is there suppose to be some kind of washer of fitting or w/e where the hardline connects to the slave? or where the hose connects to the slave.? i bled it for at least 30 minutes and it wasn't even shooting out air anymore just straight liquid..

-Did you bench bleed the master cylinder? (get all the air out of it before attaching the line)-The crusher washer goes between the soft line and the slave cylinder I believe.-Try replacing your slave cylinder. They're $15 brand new at Auto Zone.

[Spanky37]

no i didnt bench bleed the master before. . but is it possible that there is air in the line even if the bleeder is shooting out straight liquid? yeah i got a new copper washer for the soft line that connects to the slave. and i did replace the slave just today. and have been bleeding it for like 30 minutes.. its only shooting out liquid no air and the pressure isnt that great. just enough for the pedal to come back up on its own. but stilll cant get into gear

[Ni$$@n240]

What snowyred said. If you pumped the clutch with the hardline disconnected and no fitting with hose going back to the resivoir then as soon as you release the clutch it will suck air back in where the hardline threads into the master cylinder.

[Spanky37]

so take the hardline off of the master put a hose going back into the master so just cycle the fluid through it?

im not exactly understanding it

[Ni$$@n240]

Thats exactly what im saying. You can buy brake master cylinder bench bleeder kits. I would just find another brake/clutch line thread it in and bend it (but not kink it) back to the resivior. Just make sure its submerged. Even If you didnt do this you could try a pressure brake bleeder. I borrowed one from a local shop.

[Spanky37]

okay i will try and do that. but would that be the only cause of my problem in the hydraulic system?
