clutch pedal won't pop back up.

Please no flaming, I have searched the forums for my issue, and have pretty much figured out what the problem is. I would like to just know if anyone else has ran into the same problem.

When I drive my car normaly, everything is fine. I am able to press down on the clutch, and it pops back up smoothly. The problem is when I am driving the car hard, the clutch pedal will not pop back up, and I have to physically lift it with my left foot. Now, this isnt primo. I have bled the clutch multiple times, and still the issue persists. Through my research, I can only come up with that the clutch master, and/or slave are worn out and need to need replaced. So I am just go to replace both. I will check back after I install them to see if that remedied the problem.

If anyone has any input, it would be much appreciated.

there is either still air in the system, or u need to adjust the clutch pedal under the dash. it is very hard to get all the air out with the factory clutch dampner box if u haven't removed it already. to get all air out, u need to push the clutch fork all the way in by hand when bleeder released and retighten bleeder b4 releasing it while someones holding the pedal down. hope that's of some help

And if you do still have the damper, just go ahead and remove it. Its simple.

And to reiterate what he said...

After removing damper and connecting it all back together

fill master cylinder up with brake fluid, leaving lid off

pump the clutch pedal several times and on the last pump, hold the pedal down.
Then you or somebody else, loosen the bleeder valve on the slave, letting air escape. (its best to have a clear hose connected to the bleeder valve, so you can see whether or not air is coming out.)
Close bleeder valve and repeat this over until no air is coming from hose. Only fluid

Thank you for everyones input....

So, today I was able to address the problem I was having. After getting the car in the air, the first thing I did was take the dust shield off the transmission. I was looking to see how the clutch was actuating. Primarily looking to see if the throw out bearing was sticking anywhere. It works smooth, just like it should. I figured at that point my problem was definitely the clutch master and/or slave cylinders. In about an hours time, with the help of a buddy; the install of a new clutch master and slave cylinders was wrapped up. After doing the necessary bleed of the of the system. I am happy to report that the clutch pedal has better feel than it ever did. Doesnt get stuck in the floor, and clutch kicks like a boss...
