Keep in mind my car is Hydro to Cable converted.

Okay iam going to be specific with all the weird things that have been going on, ive noticed it started happening a few weeks ago, when i would race the car the clutch pedal would stay low and not come up completely, a few days ago i noticed i was running low on brake fluid, and my car would have a hard time engaging the clutch and going into gears, and today when this happened and i opened the hood and looked at the slave cylinder in the bottom front of my transmission(the one with the black rubber boot) and it was coming off and leaking brake fluid, so i went to the autopart and purchased a new slave cylinder and installed it and everything and still nothing i tried bleeding the bottom of it by the small screw in the bottom but still nothing, does anyone know what it can be??? am i bleeding correctly? or something else thats messed up
