So I got the old slave cylinder off and purchased the new one to replace it. The new one does not come with a bleeder screw and the one in my old one is done for and unable to come out much less be used again. I can't fine any bleeder screws at the auto parts store or online. What are my options? I see instructionns for bleeding without using the screw but will that still work if u don't have the screw? What are my other options????
