    I just put a new clutch on my car. I had the flywheel cut, new clutch , and new PP. I put the tranny back and started bleeding it and for some reason the pedal gets really hard and wen I go under the car and check the slave it’s completely extended outwards( with out me putting pressure on the pedal) the I bleed it and then it gets really soft and after a few time of pumping it. It goes back to be completely extended. Does any one know what this could be. Btw slave and master is brand new.

    You may need to adjust the rod on the pedal under the dash.

    I adjusted it and the farther I put the rod from the firewall the harder it gets and if I put it close it get realllllyyyyy soft and it start to stick to the floor and it just stays like that I tried little by little and I just can’t get a gear. I bled it a bunch u wasted like have bottle of the liter brake fluid

    could be the clutch line. the flexible rubber line that connects the hard lines. the inner section of the hose can collapse. when you press the pedal, there is enough pressure to force fluid past the collapsed section. when you let off the pedal there isn't enough pressure in the opposite direction to move fluid past the collapse.

    I had a similar problem like you on a clutch job a while back. In the end it was my new slave cylinder, bad out of the box. The bleeder nipple would not seal no matter how tight I tried to get it without breaking & kept let air back into the slave body. Ran almost 2 big bottle of fluid trying to bleed the air. Would keep adjusting the rod out under the dash when doing the peddle adjusting to the point it would end up blocking the master's bleed back port & then the peddle would be super hard. Gave up & let it sit over night & noticed fluid leaking around the slave bleeder nipple. Took it back for an exchange & fixed my problem.

    Sound like a bad master to be honest
    It’s not allowing the back flow of fluid and creating a hydraulic lockup
    If the master is new I would try replacing it (warranty) and bench bleed it well before installing it
    Also refer to the video that Kevin posted for a good understanding of proper adjustment
