Yet anohter clutch problem

[vinnybean]

Hey guys im just trying to figure out whats wrong with my car before i change to many parts(new master cylinder and slave). I started my car again tonight and i began pumping the clutch pedal and noticed that if i let the clutch pedal up slow while in nuetral i get a vibration in the pedal. Right now im leaning towards a clutch / TOB failure, but im going to re-bleed the hell out of the clutch to mkae sure its not just an air problem. Also im aware that im ###### in need of a clutch pedal assembly fix since i can pull the lutch up about a 1/4 inch after i let it out. and another additional note. when i put the clutch master in i put the adjustment rod practically all the way out(which i think would make me have more clutch?) or more feel in the pedal.....anyways thanks in advance

Wait, so what's the problem here? Just the vibration on the pedal in nuetral?

I had a problem like this, it was my throwout bearing, it had alot of play in it. but my problem was all across in every gear not just nuetral.

sorry for not making it a little more clear. I cant get the car into any gear with it running but with it off it goes into all fine... so while the car is running in nuetral..(since i cant get any other gear) the clutch pedal has a like vibration when i let the clutch pedal up slowly.

Tell us more about the history of the car. What led to the master and slave cylinder replacements? Was the clutch engaging prior? How are you bleeding the system?

I just had the same problem, tighten down the clutch cover bolts to 15ft. lbs. and if that dosn't fix it change the throwout bearing, and use a little assembly lube to put it together.

I bought the car for 2600 and i mean i knew it needed work. the clutch was worn for sure or at least it felt that way. after reading into dsm's i learned that the pedal assemblys wear out to(mine's worn) but yea i was just driving and then i couldnt get it into gear while running so i read some stuff about the clutch and checked to see if the master was leaking...and it was...so i changed that and then i checked the slave(pulled the boot away) and it was leaking a little to but anywasy teh car has 100000 and i figured it could use these anyways even if it wouldnt fix the problem. (and it didnt). i bled it by having a pump buddy pump the clutch about 3 times and holding. i then opened the bleeder and closed it and had him pick the pedal off the floor. i did this probably 7 times. thats it for bleeding but im going to buy some brake fluid adn re bleed it before i tear it apart adn buy a new clutch

Not necessarily, you didn't answer the most important question, how did you bleed the system? The pedal assembly also need to be adressed, 1/4" play will definitely give you problems.

i also made sure i had the master cylinder cap off while doing this

You edited your post afterwards didn't you?

You're not bleeding it properly, you need to attach a hose to the bleeder valve and submerge the other end in a container of fresh fluid to prevent air being sucked back in before you're able to close the valve fast enough. Keep bleeding until no air or dirty fluid comes out of the hose. I'm assuming that your master is probably already adjust all the way towards the cylinder piston, if so, back it off to it's default position, bleed, then readjust if need be. The bleeding procedure is also discussed in this Slave Cylinder article.

Have fun pulling the pedal assembly. Not one of the funnest jobs, but if it has to be done, go for it. But for the record, 1/4" of play doesn't sound bad at all. When I pulled mine out b/c I thought it had too much play (seemed I could pull up on the pedal about a 1/2" or maybe a bit more), everything in there was perfect. No square peg and round hole, the hole was still the same shape as it was originally. If bleeding it again doesn't work, you might try readjusting the master cylinder rod first.

yea i adjusted the rod until its practically ready to fall out of the u shaped bracket(not sure what its called). anyways do you guys think this is a bleeding problem or clutch?
