Brake Light stays on and pedal goes to floor

[twilightcall]

Thanks for the help. I removed the master and checked all of the lines. All of the lines are in good shape. The only problem is that someone had slightly rounded the head on one of the lines that goes to the master then to the proportion valve. I am going to see if I can get a new line made up. It will need to be bent to fit correctly. Has anyone bent their own lines.
