Hey guys I know it's not a Blazer but it's a close relative lol. My dad has a 91 S10 pickup with the 2.5 4 cyl and 5 spd trans. According to him the master cyl was leaking a little and he would get a low pedal and have to fill it up every few days. He put a new master cylinder on it and bled it and couldn't get any pedal at all. Then he put a new slave cylinder in it and bled everything again entirely and cannot get anything. Anybody have any ideas? I'm not familiar with the hydraulic clutches- every manual trans I've had had a cable. Thanks!

 

when i replaced mine i had to have someone in side the cab pump it up a few times then release the bleeder kinda like bleeding brakes. actually last time i did it i was able to use the hole in the floor and pump the clutch myself lol

 

Thanks I'll be over there tomorrow so I'll see if I can figure out anything. I'll try bleeding it again, etc. Maybe the master or slave are defective. Can you vacuum bleed it like brakes?
