Clutch problem

I have a 1987 chevy s10 2.8l v6, has 126,000 miles. I have a problem with the clutch. I have just replaced the master and slave cylinders and clutch will can not be presses down. It is like it is stuck on something. This happened a week ago when the clutch petal would, with every petal push, would get futher and further away from reaching the floor until it would not move at all. I then pushed hard thinking that I could get it unstuck but then broke a seal in the master cylinder, which I later replaced. The maser cylinder and slave cylinders work great I think there might be something wrong inside with the pressure plate, which is also new. Thanks for your help.
