I AM STUMPED! I recently just replaced my slave cylinder and the master cylinder by the book. Everything is installed properly and the system has been bled in many different ways, many different times. The clutch pedal has no pressure!!! The pedal will press down just enough to slowly return to its position but that's it. It barely even moves the slave cylinder. I do not understand what could possibly be happening. TIA for any suggestions or help.

 

Others have reported difficulty in bleeding the slave. Did you use the 'special tool?'

 

Was it compressed with the proper tool for bleeding. It can be made from wood and threaded rods. Search bleeding clutch, or clutch install. There are threads showing how to do it properly.

 

Yes the piston was compressed all the way. Made a home made tool.

 

I assume you installed it back in place when you pressed the clutch down and also observed the slave push the clutch fork lever forward and then come back from the force of the clutch pressure plate. If not, get a helper to push the pedal down while you look at the movement of the fork lever.
If the slave rod does not move the lever forward, then you either have air still in the line or one of the 2 clutch cylinders are still leaking (this I doubt unless you may of broke them by pushing on the pedal hard after the pedel felt hard during testing).
When I replaced the clutch and both clutch and slave cylinders a few weeks ago, I used a pressure bleeder I bought online to bleed the system because i was having tough time bleeding it the manual way. It worked perfect with no muss or fuss. It was definitely worth the $80 to buy and have in your tool arsenal for all your other cars.
If the slave rod does move the lever forward but it does not spring back from the clutch plate pressure after you release the pedal, then I am afraid your problem is with the clutch system and your cylinders are good.
Provided the clutch is good, its gotta work so keep working at it.

 

Thanks for the input. I've now got three days invested. I got close today using a vacuum to bleed the system at 15psi while adding fluid into the resevoir, until it broke. Then tried pushing the fluid up from the bottom which didn't work either.

 

Not worth the agony. Go buy yourself a pressure bleeder and get it done in 15 minutes. Its really that simple. I purchased a Motive Product power bleeder from Amazon and bled both clutch cylinders plus flushed all four brake cylinders in less than an hour. Used a total of 2 quarts of DOT 4 fluid. Its the only way to go. you wont regret it.

 

I'll check it out. I can't believe that there coil still be air In the system after how much I've bled it.

 

You may very well have all the air out and the real problem is a failing clutch system. Suggest you check the movement of the clutch fork lever travel and I discussed in my previous post before you conclude whther there is still air trapped in the hydraulic system.
