Okay so i replaces all the slave cylinder and everything cause i thought that was the problem but come to fine out i dont think it is. i bled it got pressure back in the pedal but then i couldnt get it into gear. i had to slam it into gear, and the pedal lost a little pressure it drove around fine but if i wanted to get into gear i have to slam it into gear. do you think its a bad pressure plate or?? im lost on this ive never had this problem before. the clutch pedal hasnt lost all pressure but just some and feels like it only works waaayyy at the bottom. when i got it in gear i barely lift off the clutch pedal and it engages all the way no happy medium. Let me know what you guys think it is. thanks

 

Bleed it more. Reverse bleed it if you have to.

 

And quit slamming it into gear.

 

..and learn how to spell SLAM..(do you have to Pay for spell check now?)

 

well ive been reading up and i think i need a new clutch, i can put it into gears when there car is not running, but when it is running i cant and then the pedal loses pressure again.

 

HAHA, I know how to spell slam. My bad.

 

Not sure, I think you have air in the system still.

 

No, your clutch is not disengaging. The reason why is that your clutch hydraulics is messed up. Either the master cylinder is gone (since you said the slave has already been replaced) or there is still air in the system somewhere (most likely).

 

alright sweet thanks!! ill be doing that tomorrow!! i really hope that its just that. cause it did happen randomly. i think im going to put in a new master also, even tho its only 2 years old. but screw it ill replace it. Thanks guys! keeping my fingers crossed!

 

Have someone help you. Measure the travel at the slave cylinder/clutch fork while the pedal is pushed. You should have at least half an inch of travel. Have them hold the pedal and see if the slave/fork remain fully extended or if they move and fall back quickly. IF either of those conditions are not met, you know your hydraulics are weak and either need more bleeding or are defective.

 

okay, yeah ill be doing this tomorrow so hopefully i will have good news tomorrow!! ha Thanks for the advice

 

Okay, tried bleeding it again.. still nothing. wont hold pressure. went to harbor freight and bought one of those oil pumps.... did not work and bought a brake bleeder pump deal... didnt work. maybe the pump i got is broken idk. But bled it the old fasion way and cant get enough pressure in the clutch. Anymore ideas?? what about the rubber line that goes into the slave could that line be worn out?? thats only other thing i can think of. Should i just buy a new master cylinder while im at it?? cause then everything will be new at that point. let me know what you guys think. when bleeding it it was pumping out fluid. im lost at this point

 

Did you check the pedal free play? And what do you mean by "didn't work"? Did the oil can not pump pressure, or were you just unsuccessful at getting any air out? Also, did you have someone watch the slave/fork while the clutch pedal was depressed? Does it move out then slowly come back, or does it move out and just stay?

Let me edit this for understanding:

The pedal free-play is crucial. There's a small port inside the master cylinder that connects the system to the reservoir. If the pedal free-play is too tight, that port can get covered, preventing any fluid from the reservoir to enter the system. Likewise, it will trap every bit of air in the system.

If the slave cylinder moves out and then slowly returns, that means the master (or slave) is leaking by.

The line can not go bad unless it has a rupture, or it's bulging out when the pedal is depressed. I recommend replacing both the master and slave at the same time if you're going to replace one. It's very difficult to distinguish which one has gone bad, so just bite the bullet and do them both. You can get them from Mazdatrix all together for less than $100. I'm sure parts stores sell them even cheaper.

 

i didnt check the play in the pedal, well the slave is like 2 days old im ordering a master and new line tomorrow just to replace everything. i guell ill check the pedal play tomorrow. i just dont understand why randomly driving all this happend cause i was just cruising down the interstate and then got off and noticed that my pedal was losing pressure and then alomost lost all of it when i got to my friends.

well fluid was coming out of the reservoir.

 

so are you saying the slave should move quickly? i will check that tomorrow. but i cant really keep pressure in the pedal. so maybe it is the master.

 

In terms of setting "pedal free play" here is the easiest way to explain it:

Follow the clutch pedal up to the actuating rod that goes into the master cyl. There will be a 10mm nut cast into the rod, and a 12mm nut adjacent to that. Loosen the 12mm nut and spin it off of the 10mm nut several turns.

Now with the pedal at rest, rotate the 10mm nut/rod BY HAND in such a way as to extend it further into the MC/firewall. Eventually you will feel more resistance, in other words you'll feel it touch the MC and it will get hard to turn by hand. Stop here and back off about a turn, and when you're done you should be able to move the pedal just about 1/4 of an inch before you feel it encounter resistance. Leave the adjustment alone at that point.

IF the adjustment is set too far "out" (too much freeplay) you won't be compressing the hydraulics more than halfway and you will never get good pressure and a good feel to the clutch....and you might not even be able to bleed it.

If the adjustment is set too far "in" (no freeplay, also called "preloading") then it will also be hard to bleed because of the reason Agreen mentioned.

 

Thanks, I adjusted it! feels great! Clutch grabs real quick now! That was my problem all along. it was weird when i went to go adjust all that. The 12mm nut was already backed off the 10mm. think that might of caused the random proablem?

 

How long have you had the car? Unless it wasn't torqued down it shouldn't have unscrewed by itself. There's not a bump stop is there? Don't remember.Could have fallen off causing the clearance problem.
