Got it fixed !!!!
The cruise was not working, but everything else was ok.
I checked the fuses. fuse 13 and fuse E were ok.
I checked the Brake switch on the brake pedal. It was ok.
I checked the redundant brake switch on the master cylinder. It was ok.
I took the servo out (2 bolts and disconnect the throttle attachment). Took it to a junk yard near my house. The junk man had a 92 F150 in the back of the junk yard. We pulled the servo off, and installed it on my 1996 F150. He charged me $75. Works like new.
Thanks for the help.
