Brake light problem!

I have a problem with My 93 F150 4.9, when I'm slowing for a stop My brake lights come on but as the truck slowes to around 10 or 15 miles an hour the lights go out! It's like the pressure to activate the switch mounted on the brake pedal arm is greater than the pressure it takes to activate the brakes! The truck has new brakes all around including hardware and a new brake switch that was changed out with no difference to the brake light problem! I've checked out the power brake booster and it seems to be fine. also the pedal pressure and height is good!

The brake switch has to be adjusted to where it follows the pressure on the pedal evenly, if it's done right you should be able to press the pedal down 3" let up 1" (light will shut off) and the next fraction of an inch back down should flip them on again. Who did the brake job?
