Yes you are correct if you take the pressure switch out it will leak out brake fluid.
Just disconnect the connector at the pressure switch with the truck running and check if there is 12v on one of the two pins. Without power coming to the pressure switch we can try and find out why.
I had a cruise control problem and I replaced the cruise control module and the pressure switch. It turned out that I had a wire cut under the hood that comes from the pressure switch. Once I repaired the broken wire it was fine. Not saying you will have this problem but in my searching I have found this is one of the first diagnostic things to look for.
Here is one of the many threads that talks a bit about the cruise control problems people were experiencing: Cruise Control Not Working
Searching treads using mobile is not as good as searching on the desk top version.

I have forgotten what each letter stands for, the report will tell you any open recalls, warranty repairs, and the original equipment from the factory among other things.

CC = Cruise Control
Have you performed the diagnostic test on the cruise control yet? There is a thread here that explains how to put your truck into check mode for the CC... Let me see if I can find it.
If memory serves me right, the switch on the Master Cylinder is called the "Deactivator Switch", and when it fails, it fails to the 'open' position for safety reasons.
Here is a diagnostic test you can perform on some models:
Enter the Self-Test Diagnostics by depressing the speed control OFF switch while turning the ignition key ON, making sure the engine does not start and is not running. The speed control indicator on the instrument panel will flash once to indicate that speed control module entered the diagnostic mode. FIVE ADDITIONAL FLASHES AT THIS POINT INDICATE A DEFECTIVE SPEED CONTROL SERVO. Release the OFF switch.
Press the remaining switches in this sequence: ON, RESUME, COAST and SET/ACCEL.
If the "ON" switch is not depressed within five seconds after entering the diagnostic mode, the module times out and the procedure must be started over.
The speed control indicator lamp will flash as each switch is depressed. Press each switch in the sequence immediately after the indicator light goes out for the previous switch.
NOTE: There will be a slight delay when the last button is pressed and the lamp flashes.
A lamp flash with the last button (SET/ACCEL) indicates that the STATIC test passed. If the lamp does not flash with the last button and there are no additional flashes of the lamp, the switch is defective.
If the lamp does not flash with the last button, and additional flashes occur, follow the chart below for trouble codes:
Flashes Source
2 Flashes BPP defective, circuit is defective, brake applied, CPP switch or jumper (if equipped) is defective
3 Flashes Deactivator switch is open or circuit defective
4 Flashes Vehicle speed signal is out of range or circuit is defective

I'm just posting this for reference:
If it turns out to be the Servo Module you can grab one off a Taurus for a lot cheaper. Here is the link: Heres How TO Replace Your Super Duty Cruise Control Servo For Cheap
