Clutch cylinder(s)

Hey guys, I think I may have a problem with one or both of my clutch cylinders. Tell my what you think...

This has never happened to me until this morning, on my way into work, and it happened 4 or 5 times so I turned around and came home.

I was on my way into work, got around the corner from my house, and was coming up to a stop sign. I hit my clutch pedal (all the way to the ground), but noticed I was still engine braking for like a second or 2 before the clutch actually disengaged. I thought maybe I was just psyching myself out... so I put it in first, and start driving down the road. When I went to shift from 1st to second... I noticed that getting it out of first, it felt like I was taking it out of gear without hitting the clutch, and then it wouldn't go into second (or any other gear, including first) at all. The gearbox PHYSICALLY felt like my foot wasn't down on the clutch at all... it just wouldn't go into ANY gear. Like, I DON'T mean that I put the shifter knob into the first gear position, and then just couldn't get the clutch to engage... I mean that I could push the clutch pedal all the way to the floor, but then physically could not push the shift knob into any gear. Start your car, and try to place your shift knob into any gear WITHOUT pushing your clutch pedal down at all... that's what it felt like... So I coasted off to the side of the road, and parked up, and turned my car off for a few minutes. Turned it back on and it still wouldn't go into gear. After a couple minutes of holding my foot down all the way on the clutch pedal, and trying my damndest to get it into gear, it finally went in. I actually heard the clutch engage, sounded like it was stuck and suddenly became unstuck or something, kind of like a click/pop. I drove it back to my house and it was still doing it, I would have to hold my foot down on the pedal for a long time (like 3-5 seconds at least) before the clutch would actually engage... and I could feel/hear it every time it actually did.

I'm confused as to whether this is my actual clutch (like the pressure plate and disc) or if it is a hydraulic problem somewhere between my foot and the slave cylinder. If I had to guess, I'd say it's a cylinder problem, and the lubrication points could probably stand to be re-lubed.

Also, I noticed that whoever had the car before me... it doesn't look like it's brake fluid in my clutch reservoir. It smells like effin' windex or something, so I'm going to be bleeding/refilling that at the very least.

How expensive/hard is it to replace the master/slave cylinders?

bump for more opinions. Does this even sound like a clutch cylinder problem? My neighbor said I might need to add tranny fluid, which I do believe I have to do, but I don't think that is what is causing the problem I described.

It happened to me again last night when I tried to drive it again. Seems like the slave cylinder is not disengaging the clutch "enough". When it happens, the clutch pedal feels very stiff to push all the way to the floor all of a sudden. And you know how normally when you push your clutch pedal all the way to the floor, there are like a few inches of play between where your clutch FULLY disengages, and when your foot hits the floor? Well, that little bit of play disappears... it seems that even when my foot is all the way onto the floor, the clutch isn't fully disengaged. Also, last night when it happened, I had to get the car home somehow, so what I did was turn the car off completely, put the shift-knob in the first gear position, and then start the car up, and that would at least get me into first gear so I could get the car home (I was only around the corner from my house)... and when I did that, as I would engage the clutch by lifting my foot.... it felt "lumpy" under my foot. Like it wasn't a smooth engagement... Also, this morning I had to move the car, so I did my technique of placing it in first, depressing the clutch, and THEN starting the car, and when the car started up, even with my foot ALL the way depressed onto the clutch, the car started to move forward slowly as if I was feathering off slightly (and before you ask... yes the car was on even ground, and no it wasn't moving on its own before I started the engine... only after i started the engine did it start to creep forward)

What do you guys think?

I just found this on a random automotive website... and this describes my problem pretty well.

"Dragging and Disengagement Problems — If the gears grind when shifting or the clutch fails to completely disengage when the pedal is depressed all the way to the floor, the clutch disc may be dragging against the flywheel or pressure plate. The most likely causes here would be insufficient linkage travel (check the adjustment), a damaged clutch disc (loose or warped friction linings, or a damaged or bent hub), a broken release lever on a coil spring clutch cover, binding or rust on the input shaft or a broken powertrain mount.

If you suspect the clutch disc is dragging, try this test: with the engine and transmission at normal temperature, push the clutch pedal all the way to the floor, wait five or six seconds, then shift the transaxle into reverse. If the transaxle does not shift smoothly, the clutch disc is dragging."

What do you guys think, time for a whole new clutch?

Re: Clutch cylinder(s)

I having a similar problem. I started the car back it out shifted in 1st gear none of the gears went in. I turned off the engine shifted in 1st then started the engine with the clutch on the floor. The car started to move as soon as the engine started i have to hit the brake to stop the car from moving.
I was 3 miles away from home so I shift in gears with RPM like driving a big truck. went home it disappear, I shift in gear fine. Drove for a while got new timing belt . Bleed the clutch in the after noon , started the car in the morning the clutch had no pressure. pumb the clutch for couple times it got pressure back. I went out and got the master cylinder replace. drove around thought it ok but after around 70 miles highway and local. Stop by a gas station turned off the engine. Started it again oops it won't shift in any gears turned off the engine turned it back on it ok . So now I think I didn't fix the problem yet it was just yesterday so I can't figure it out what is wrong with it yet. I had bring it to a machenic it nothing wrong when I brought it there. Let me know how are you going to fix this.

Re: Clutch cylinder(s)

its almost impossible to bleed the clutch system entirely of air with only one person, you basically NEED 2 people.

also, it's MUCH easier to bench bleed the master cylinder of ALLL the air before going on to bleed the slave. basically fill the master cylinder with DOT3, run a hose from the outlet of the master back up so the other end of the hose is in the reservoir of the master. pump the master like 20-30 times to rid ALLLLL the air in the master, then connect the clutch line and start bleeding the slave.
