Hello, shanedaff, Welcome to the Chevrolet Forums.


It's been a while since I've done this, but IIRC, you have to get

pressure at the clutch master cylinder first. It's the same procedure,

pretty much, as bleeding the brake master cylinder.

1. Leave the CMC bolted to the firewall, if it's not level, gently raise

the rear of the vehicle till it is. Use proper support after jacking,

2. Bleed the CMC, using a tube from the CMC bleeder screw back into

the CMC resevoir. Pump gently, so as not to splash fluid about.

3. Then when you pop the bleeder screw at the slave cylinder,

it should purge the air downward thru the line from the CMC,

(keep a CLOSE eye on the fluid level) to the CSC.

4. Basically, the slave cylinder is the most remote item in the hydraulic

system, so it bleeds last. Once you purge the air from the line thru

the slave cylinder, the slave cylinder should bleed fairly easily. Once

you are done bleeding the CMC, top off the CMC resevoir every couple bleed

attempts, and keep the lid on the CMC as you bleed the line and slave

cylinder.


BE EXTREMELY CAREFUL NOT TO GET HYDRAULIC FLUID ON THE PAINT.

It's very caustic, and will strip your paint in an instant.

systems with hydraulic release bearings are hard to bleed. After trying bleeding the master, gravity, vacuum and pressure bleeding one system I still had no pedal. Even after 2liters of fluid went through the system.




the only thing that worked was 10 fast pumps then holding the pedal down for 1min. then while still keeping the pedal down have someone crack the bleeder. repeat.

I have to agree. You should also try this.

shanedaff

the normal way of pumping the clutch then opening the bleeder valve does not work. also tried leaving the reservoir open and the pedal depressed overnight, someone said that would work and it didnt.

Hi shanedaff

I have the same problem on my chevy pick up. Did you find a way to bleed that clutch?

I found the trouble. I had to change de slave cylinder . When I pulled out the transmission, the bushing that is located in the flywhheel felt down between the clutch plate and the pusher plate and I didn't see because I didn't have to remove those parts. When I put back the transmission the bushing stayed in the clutch. So when I tried to bleed the clutch It was as though some air was in the system but it was the bushing who jammed the clutch.
