alright i just replaced the slave and master cylinders on my clutch and the hose leading to the slave cuz it was leaking somewhere so i just replaced it all. now im trying to bleed it and am getting nowhere. i bench bled the master and then i unbolted the slave and held the piston in with a c clamp and bled it above the other lines to try to get the air to rise and i still have no pressure in the pedal. and their is no bubbles in the container that im bleeding it into. ive been doin it for like an hour straight with no progress. any ideas? thanks.

 

It often takes a bit of time to bleed the clutch hydraulics, but an hour or more is extreme. What is your procedure for bleeding the system? Unless you have a speedbleeder screw in the slave, you need to press the pedal to the floor and hold it there while someone else loosens the screw and tightens it before letting up the pedal. And doing that a number of times before you get a firm pedal. Sorry if that is a bit basic, but obviously something is not right here.

 

when i did mine, i made the mistake of putting the pushrod in backwards, so everytime i pushed in the pedal, the pushrod would move, but it would go right through the hole. check and make sure you have it facing the right way.

 

ya i bled it by having someonee push the pedal while i loosend the valve. i had a hose goin from the bleeder to a container with some brake fluid in it like my manual said. and which pushrod? also the rod on she shift pedal that goes into the master is bent where the treads are to adjust it, it still seems to push in fine but is it supose to be like that? ive bled brakes a million times and had no trouble so i dont think im actually bleeding it wrong.

 

Perhaps the C-clamp approach is the problem. If I understand what you said about that procedure, it seems to me that if the push rod on the slave is not able to move when you press the clutch pedal, the internal space in the slave will not fill with fluid. No need to hold the slave above the hard line to bleed the system. If you haven't done so already, install the slave and bleed it from there.

Other than that, look for leaks where air may be getting into the system. The clutch pedal should not be a problem if it worked OK before. However, have a look at the bracket under the dash where the clutch pedal assembly is mounted to the firewall. Could be that bracket is broken and the pedal is not actually pressing on the master cylinder. You could also remove the master from the firewall and verify that the pedal rod is actually moving when you press on the pedal. Just a thought.

 

i put the slave back on and tried bleeding it and still nothing. i then took the slave off and coverd the hose that goes into with my finger and bled it to make sure all the air in it was out. put the slave back on and still nothing. all there is is little tiny bubbles in the fluid but trust me its definitly not enough to be the problem. even when i pump the pedal 50 times i dont get any pressure. if i dont get this fixed in the next couple days the cars goin to the junk yard its a peice of **** anyways.

 

please help. i think somthing else has to be wrong but i dont know what. all the fydraulics are new. i looked and the rod is going into the master. their is plenty of fluid coming out when i bleed just no air. what else could it be? i can see the slave pushing the fork on the trans some but not that much.

 

If your old slave worked, aside from the minor leak you apparently had, put it back on and try bleeding that. Possible that the new, I assume a reman, was not rebuilt properly.

Since the slave shaft is moving the clutch fork "some" can you shift the car with the pedal on the floor?

 

ok..ths styx version..cost about 75 cents!
I fill the system with fluid.,get a piece of tubing.Clear tubng.(.75 cents!).

put it over the slave bleeder so you can see the fluid in the hose when you crack the bleeder.
Now comes the fun part.
Fill the master with fluid,and leave the top off the master reservoir.
once the hose is ON the slave,crack the bleeder and SUCK on the Hose(seriously!).
That will bring fluid to the slave.Once you create that "vacuum effect" what will happen is the fluid gets Sucked into the slave's "reservoir"
So once you see fluid in the hose,shut the bleeder and make sure the master is topped up.Put the cap ON the master.
Make sure the hose is on,and that the Air in the hose doe not settle at the bleeder opening.
Now,STEP ONE:get a buddy to PUSH the Clutch in.Crack the bleeder..It will "spit" fluid and Air into the hose..Close the bleeder...Repeat Step One until you see that there is no air in the hose when you crack the bleeder...BAM!,you are DONE!
NOTE:Make sure that when you are bleeding the system that you don't let air into the slave.
Also,make sure that the master does not go empty,or else you have to start again at the beginning.

 

i was thinkin i might have got a bad slave to. i baught it off mazda trix so are they usually pretty cool about replacing stuff? and when i bled my clutch i didnt suck the fluid through the tube but i did use a clear tube and i could see fluid going in anyway so i dont see why i would need to suck it through to get it started. but hell ill try anyway. the only thing that looks like it could be the problem is the rod going through the firewall off the clutch pedal is bent and rubs on the side of the whole when it goes through. when i take the master off it pushes out fine just at an angle. i would think the master would make it go straight but i cant help but think it might not be pushing all the way. its bent right on the threads where you ajust it. i think i bent it after it stoped working cause i put an old slave on that i later found out was seized and i pushed the pedal down as hard as i could anyway cuz i was pissed.thanks for all the help hopfully this will get fixed sometime soon.

 

i also tried to push the master with a screwdriver when it was off the firewall but still connected to the system and i couldnt get it even when i loosened the bleeder on the slave. i dont know if that means anything or not? and no i cant shift the car into gear even though it moves the fork a little. maybe if really forced it but its up on jacks so i didnt wat to try to hard and the wheels started spining!
