    Hey, so I have a 1982 seca 750 that I can't bleed the brakes

    PHOTO ATTACHED

    When I Pull the lever in the little rod that enters the master cylinder (the one in the photo that the cable is attached to) goes in but the thing inside the master cylinder that the rod pushes on doesn't return out when I let go of the lever and the rod is no longer touching it.

    Is there a spring or something in there that might be seized?

    How difficult is it to take apart or replace does anybody know?

    I am having the same issue. I have pressure at all the air bleed locations just fine, but the MC will not pressurize enough for the brakes to engage. I will be trying the reverse bleed method soon. Very frustrating indeed.
