2g FWD Clutch Problems

[j_biggz]

I have a 97 Gst 5 speed and it seem like when you have the clutch to the floor and rev it to 7-7500 rpms the car will move forward. I found a video on youtube about how to adjust your clutch via the clutch pedal and slave solenoid. Well this information doesnt coincide with my car. From what I was able to find mine is not adjustable. I bleed the lines via the bleeder valve and did get some air but the problem persists. Occasionally the pedal will stick to the floor. I do get some clicking from what I believe is the master solenoid but I am unsure. Anyone ever have a similar experience?

Is this the info you read on bleeding / adjusting the clutch?
Frequently Asked Questions

If not go through that and read. The main things you will adjust is the clutch pedal stop at the top and the master cylinder rod that attaches to the clutch pedal. You will have to get up under the dash to adjust these and it helps to have a friend with you.

But it sounds like your clutch is not adjusted properly and it is still dragging even with the pedal being pushed.

Apparently my "mechanic" doesnt know how to bleed the lines. He had me " pumping up the clutch" and then holding it about half way as he bleed the line. I still have some brake fluid left over an will try this correct method again tomorrow. If my car is front wheel drive do I need to have all four tires off the ground to do the clutch reality test?

No only the front ones.

And pumping up the pedal is a big no-no. One other thing that i did to help remove air and improve pedal feel was to eliminate the accumulator on the front of the trans and go to a stainless clutch line from the metal line right to the slave.

Okay Dude, Bro, Buddy, Dsmer, Grasshoppa. I have my fair share of clutch problems. How is your master and did you do the usual bs like check for leaks and slave cylinder crap?
Does your pedal fall to the floor while the car is moving or does it fall down when you drive and coming to a stop and then it sinks by itself?
You might want to check your master. Inside there is a white plastic piece I think that can break causing the pedal to sink to the floor. Your only cure for that will be by a new OEM master cylinder.
If that is the case, bleeding will not help at all. Do not buy a longer slave rod or adjust the master so low to a certain point. Most will tell you this but those methods are only a band aid.
I'm assuming your not having slippage or anything.
I'll subscribe and try to help you!

So this is what my clutch is doing. If you put it in gear and rev it to 7000rpms the car was moving in 1st gear with the clutch pinned on the floor. I bleed the lines wrong tho and will have to do that again. The clutch pedal sticks to the floor periodically and is usually when Im driving. its not stuck all the way but about 2-3 inches or so off the floor. To my knowledge there is no leak an I have checked the clutch master and slave cylinders. The slave isnt accessible and I believe the master is going bad. Getting some clicking from it. Other than all that I have no clutch slippage or any other problems. Well it doesnt like to down shift to second but I think that was from the guy I bought it from not knowing how to drive and has little to do with the clutch but maybe not. Here are some pictures of the clutch pedal and the slave cylinder.

Is this the video you were talking of?

Sounds to me you have a dragging clutch if it moves in first gear with depressed clutch at 7000+ rpm.

Then again I'm not a expert in manual cars and have yet to experience one until recently picked up talon.

Rule of thumb fix the cheap stuff and work your way up to expensive stuff.

Exactly what I was gonna say. Since most if not all of the free test are out of the way. If you think you bleed it wrong redo it again with the proper way.
I would suggest replacing your master cylinder. On the side note thanks for the pix. It helped somewhat. I'm confused on the master cylinder and why there isn't an adjustment rod. Haven't seen that type or been in that year of car but I'm assuming their all the same. Your best bet will be buy an oem unit from STM or another vendor. Since I don't know the mileage of your car I guess it wouldn't hurt to do some manual maintenance.
I would recommend replacing both slave and master to rule out the problem but that's on you. Piece of mind is priceless for me

Here some reference to show you what I"m talking about. I had this problem and replacing my master cured it.
2G "Ghost Pedal"

On very light foot pressure on a 2Gthe pedal drops to the floor all by it's self. ?? Yes. The little rubber seal in the pic above gets a little nick in it or a piece of dirt under it. On a regular pedal push, the seal seals fine and the clutch works normally. On a very light push, the seal does not seal well and fluid will bypass it. Since the 2Gs have a heavy assist spring, the additional assist is enough pressure to keep the pedal going towards the floor all alone. Quite disturbing to watch. Replacing or rebuilding the master cylinder will fix this.

Good Luck and I hope you fix it!
