Vadien Posted December 30, 2018 Share Posted December 30, 2018 Just bought a 1988 Comanche and one of the problems it had was that the clutch was super hard and would just stick all the way to the floor. I figured out the clutch master cylinder was stuck so I bought a new one and replaced it. Now i'm trying to bleed the system and the clutch is super soft and I guess I can't get all the air out of the system maybe. I noticed when I remove the pipe off of the slave cylinder and press the clutch theres not much pressure coming out of the lines. I can hold the pressure with my finger. With the master cylinder out it feels like it has decent pressure if I push the rod with my hand. Anyone had this problem and know whats wrong?

Pete M Posted December 30, 2018 Share Posted December 30, 2018 did you bench-bleed the master before installation? Link to comment Share on other sites More sharing options...

Pete M Posted December 30, 2018 Share Posted December 30, 2018 it is highly recommended as bubbles in the master are real hard to remove. Link to comment Share on other sites More sharing options...

If I get some kind of vacuum pump bleeder kit would that work with the master already installed? I'm not to knowledgeable on bleeding clutch systems and don't know the process to bleed the master on a bench. I'm guessing I have to hook up some lines to it or something while pumping it?

cruiser54 Posted December 31, 2018 Share Posted December 31, 2018 Also check to see if the tang on the pedal itself hasn't popped the weld. Link to comment Share on other sites More sharing options...
