Question about 1998 Toyota Tacoma
I had my local mechanic (who is cerified) put a new clutch in my truck a couple of months ago. I was told at that time I might also need a slave cylinder. Yesterday, it started getting hard to change gears, and then would not engage. The clutch pedal also lost all pressure. I went ahead and put a slave cylinder on hoping that was the problem. After installing the slave and bleeding the system, no change. I bled it several times so I am sure there is no air in the line. Finally, for whatever reason, I got a good firm push on the clutch pedal. FOR JUST ONE PUMP. Then it went back to no pressure at all. I checked the slave cylinder and saw the piston was completely pushed out of the slave. I took it back off and reinstalled it. Now I am back to now pressure. I also took off the clutch master cylinder to check for leaks. There are no leaks in the master, slave or lines. I have no idea what to do now.
check the helper spring on the clutch pedal. You'll have to get down in the driver's footwell and using a flashlight look at the mechanism while you push the pedal down (and pull up). If the spring isn't missing or broken and everything looks okay, then change the clutch master cylinder. The piston in the cylinder is probably binding due to corrosion in the bore. I have an 1986 and had the same problem. Changing the clutch master cylinder fixed it.

Definetly your slave cylinder. Seen it several times on toyotas in my career. I do suggest buying a new slave cylinder rather than trying a rebuild kit. I've had customers that requested a simple rebuild kit in the past, and had them fail within a few months. I know my guys, and I personally rebuilt them correctly, but they still failed. I've never had a customer return with a complaint on a new one. The repair itself is very simple, and if you buy a new one, you should be fine for a good long time.
I hope this helps you, and I wish you luck on your repair.

My best guess on this, assuming that the clutch master is working and it has no air remaining in the system is that you either have the wrong throwout bearing in there or that it is installed incorrectly. Also, rare but can happen is that if the pressure plate assembly is a rebuilt one, the face has been cut too far and clearances are off.
Obviously, check everything external before taking it apart again, but that's where I think you will need to go.

Testimonial: "thanks did have some issues installing throw out bearing so maybe that is my problem"
A clutch pedal not springing back is almost always an indication that there is air in the system. Bleeding out a clutch is a tedious endeavor to say the least.
I suggest you open up the bleeder screw & gravity bleed the clutch.(This will take a long time as well!)
