'94 4Runner clutch issues

[VA.CRUISER]

I put a new clutch set,master, and slave in my moms '94 4Runner due to the old clutch slipping. Now the problem is the clutch still doesn't seem to want to disengage right. The petal wants to stick to the floor when you first get in it and then after driving awhile fighting it to shift it will get better. I have adjusted the pushrod already which seem to help for awhile but now this is going on any ideas?

Thanks guys

First off, I know nothing about 4runners.

Could there be a return spring that has worn out?

 

[KLF]

There should be a long spring under the dash that pulls the pedal back away from the firewall when you take your foot off, make sure it's still there.

Check the pedal bracket very carefully under the dash, make sure there are no cracks in the bracket near the pedal pivot. Common problem that is easy to overlook.

Did you have the flywheel turned when you swapped the clutch? If so, did they re-machine the "step" in the flywheel? That step is very important, the clutch won't work properly if it's not there. There's a thread on here where it was discussed recently, maybe search for it.

X2 on the return spring under the dash!

Thanks guys I'll double check the spring and the the bracket KLF, would this also now cause it to shift so hard now ? It had no problems shifting before doing everything and Bluecruiser84 I hear you I don't know much about the 4runners just cruisers

if you are not getting a full stroke on your clutch master, then your slave will not disengage your clutch making it hard to shift, you need to bleed it and make sure you are getting movement to your slave.

where abin VA are you, are you close to Jefferson county WV.

Winchester so yea close and thanks I suspect the slave even after I have bleed everything already need to double check

toy4xfun- did I meet you at the Fall Crawl this year ?

 

[toy4xfun]

no sir i did not make it this year!


you will need some one to pump it while you watch the slave.

Sticks work too. I just push it in by hand, jam a stick in to hold it. Then I look at the travel, and pull on the string to pull the stick out while looking where it releases to.

Yeah that spring and base crack are common problems. Sometimes the spring just goes soft over time and just needs replacing. You can always lift the pedal with your foot and see if it then works when pressed.

Improper bleeding can also be the culprit. Air bubbles suck. When bleeding I always run a few OZ of fluid through after it starts to come out the bleed hole. That helps get a majority of the bubbles out of the system. Some things require pumping to get all the air out. If so, do it. I've used a couple boards to make a lever to actuate the pedal by hand when I don't have an assistant. That allows me to watch the bleed hole while I'm pumping the pedal.

Update:

Well I finally got a chance to check things out this is where I'm at now. First did not find any indications of cracks in the bracket,it has a weird pedal return spring looks like a V not a long spring like you would think maybe weak??? Also found had very little movement in the pushrod from slave cyl. Removed master and bench bleed again reinstalled, found little pressure at slave cyl. even after several attempts to get more so I suspect the slave is leaking by internally. So stopped by my friendly NAPA store and my guy there is covering for me and getting me a new one in the morning

Thanks to everyone helping me with this problem

PITA!!!

the pedal will also push in a little crooked if this is your problem...

I think youre suppose to bench bleed the slaves on these too...doesnt make sense to me but I read it somewhere...

I suspect your master cylinder.

I have a friend with a Tacoma. On the Taco there is a funky spring on the pedal to lighten the pedal pressure. Well, her master gave out, and the pedal would, under it's own control, just drop to the floor and stay there. The master cylinder was unable to maintain pressure and the spring had enough force to bypass fluid in the cylinder itself. Damnist thing I've ever seen.

I did several fluid changes trying to figure it out, until I realized the slave was not moving.
