    th assembly. My 86 1/2 ton has the 465 4 speed and before i blew the rearend, she leaked fluid frequently and i always had to keep an eye on the master cylinder level. The truck has been sitting for about a month now, and just yesterday i went out there to move it and the clutch pedal is dead. Feels like its disconnected. So i bit the bullet and went and got a new $90 slave cylinder (thats were all the fluid seemed to be leaking from) changed that and, naturally, problem still remains. Does this thing need to be bled or something? theres no fluid around the master cylinder or anything, it looks good. I'm just hoping i don't have to change that too, its $80 bucks too. I need money for my axles/lift/wheels/tires. Not this [censored]. any help would be appreciated. I looked under the dash, everything looks fine, plus i haven't touched the truck in a month. Pedal is completely weak, like i said, almost like its not connected....

    Yes you need to bleed it....somewhere I saw a write up about bleeding a Corvette hydraulic clutch. just like the trucks, the article said the common (and GM's way i believe) are wrong. I think you have to remove the slave cylinder from the bellhousing, and bleed it from there. I think bleeding it like the brakes will work, except the cylinder should be held at a 45 degree angle, with the bleed valve at the "high" end. Someone correct me if I'm wrong..you may want to search out a "corvette hydraulic clutch bleeding article online"...think i will try to go find one now...
