I just had the clutch line and slave cylinder replaced and bled in my 1995 S10 with NV3500 transmission, but I can't get the clutch to disengage. I checked the slave cylinder travel through the inspection hole, it's moving about 1/2 inch which doesn't seem like enough to me. Does anyone know the distance required to disengage the clutch, or is there another problem? I paid $226 for a local shop to do the job for me to save me the headache and now I'm wondering if they did the job correctly or not.

Welcome to the site. I'll have to read my 96 factory manual. It may state how much travel is needed to disengage the clutch.

Read this post. Another board member was having similar issues with line bleeding.

Thanks for the reply! I've looked everywhere in my repair manual, all it says is the slave should extend "substantially". I'm not sure which post you're referring to, as there is no link in your reply!

[EDIT]: Took the truck back down to the shop today. Had no clutch pressure at all until I pumped the pedal about 20 times, then it was working perfectly. Air bubble trapped in the line maybe?

Probably. Bleeding slave cylinders is not easy. Gravity and pump bleeding eventually work. My dad had the same problem on a new slave cylinder. Eventually the new slave cylinder had to be replaced. I assume a seal on it was leaking.

Good to know you got it working again!! Seems you and I have some of the oldest S10's still running.

I ended up cracking my hard line and had to purchase a new one. I ended up using the rod connected to the slave piston to bleed the line. Pushed it against the frame several times until I couldn’t get it to move. After that, it was fine.

You’re right. It’s a pain to bleed them.

So I'm thinking the reason the shop couldn't bleed the line completely is because the pedal linkage is fully adjusted and I'm not getting enough fluid volume into the line. I'm going to try to back the linkage out and bleed it again myself to see if that makes a difference. I'm sure I'll be blowing a seal in the slave if I don't figure something out soon.
