    AI says these cars have a slave cylinder. I believe its full of bs. I have one on my rod and was watching a video on bleeding the clutch system and it said to block off the slave with a clamp. I was wondering if thats to get the air out of the master.

    What are you talking about? All hydraulic systems have a master and slave cylinders

    I am saying that old muscle cars dont have hydraulic clutches like AI says. They use a Zbar.

    Ai probably 60% wrong ..,

    Yes & No on clamp on hose to a certain
    Extent , air will rise if cap left off ,
    50/50 that all air will escape.

    Some time's it like changing a brake line
    Gravity letting brake fluid drip from
    Higher up from reservoir with top off, & other line still full of fluid
    To top of fitting .
    You can attach fitting there will be no air. Self bleed @ connection.

    If all new crack bleeder , let gravity feed
    Then bleed like a brake master cylinder.

    I have heard of Z bar , I call it clutch Fork & rod or cable

    The video showed the clamp pushing the slave piston in while bleeding, not the hose.

    I wanted your thoughts on compressing the slave while bleeding. Not a bunch of riddles.

    then why did you mention ai?

    sheesh.

    Just ask the question you want the answer to.

    Yes, that was probably to bleed the master cylinder.

    Do not know witch style you have
    I would say when you push clutch peddle down the Save extend , if so
    Crack bleeder then use a C clamp or wide jaw Vice grips , to collapse rod ,
    Or unbolt push back with fingers ,
    So no air pocket on piston , completely collapsed With bleeder open should gravity bleed.
    You can do same bleed method on disc calipers by completely compressing the piston up into the caliper, then just let gravity bleed,wants done pump black slow
    Top off Master cylinder.
    Wheel cylinder also.
