So I'm having an issue with my 1991 5speed 3.0 4 runner. When I back out of my driveway I have difficulty shifting out of reverse into neutral. Also sometimes the clutch will stick to the floor and I have to pull it back up myself. I have replaced the clutch pedal bracket about a year ago. I noticed the fluid was low last weekend so I topped it off last weekend. Any ideas?

Bleed the system, sounds like you've got air in there somewhere.

air in the system or clutch slave or clutch master is failing

When there is air in the system does it mean the clutch is more responsive? Sometimes I barley let the clutch off the floor less than an inch and it engages.

Yes. could be that or a worn out clutch but i would bleed the system first.

If there's air in the system, the clutch won't fully dis-engage, so as soon as you pull the pedal up even the slightest, it really grabs.

Bleeding take about 5 minutes with two people. There's a small nipple on the slave cylinder underneath the truck. Have a person pump the pedal a few times, and then hold the clutch down. Get underneath, hold a container underneath the nipple, and loosen it with a wrench (8-10mm I think). You'll get a bunch of fluid pouring out, as well as some bubbles (Sometimes it's a good idea to stick a small length of tubing on the end of the nipple so that it doesn't squirt everywhere, and you can see the bubbles). Once it stops flowing, close it up, and have them let up on the pedal. Repeat this procedure this several times. You'll have to keep an eye on the fluid level up top, make sure you top it off when it gets low.

It's just like bleeding the brakes.... Only with the clutch pedal (obviously).

I bled the clutch and didn't seem to have an effect. So now I'm guessing its a bad clutch master cylinder?

I replaced the clutch master cylinder and tried rebleeding the system but it hasn't helped. Any idea's? Perhaps the slave cylinder is bad too?

Could be the slave, check all the lines/components of the clutch system and make sure there are no leaks anywhere.

Should I see the slave cylinder boot thingy move when the clutch is pushed down?

Fo by Fo

Also, is the clutch release cylinder the same as the slave cylinder?

mattaway

Yeah, the slave boot will move when the clutch pedal is pushed. Never heard of a clutch release cylinder, but sounds like it could be another name for a slave cylinder.

I ended up bleeding the system again (and bench bled the cylinder this time) and its all working now, plus no more reverse grind! Thanks for the help guys. What would I do without yotatech?
