First question is: 1. Is the pedal fading to the floor and the 'hard' you are describing is just that the pedal is at the floor? When replacing a master cylinder on these Fords, it can be a pain to properly 'bleed' the master cylinder and then the complete brake system.

These switches are common failures, but tilt columns also suffer from binding in the column and the gear that the ignition switch turns. Attached below is my YouTube video on changing the turn signal switch, but it also shows how to remove the ignition assembly and how to take the steering column apart. With it apart you can inspect all the moving parts, lubricate the gear and ignition switch housing.
