soft peddle feel maybe from a damaged brake master cylinder. this pressurizes the peddle, and if there is a leak in the cylinder it might feel soft or flop all the way to the floor.
Check for wheel bearing play. Check that the pads are in good condition and not falling apart. Check the brake master cylinder seals have not failed. Check that there is no loss of fluid from the system. Check the age of the brake fluid. Ensure the braking system has been properly and completely bled in the correct order.
If the brake pedal is soft on a 1997 Ford F-150, then there is a good chance that there is air in the brake line. This can be remedied by bleeding the brakes system.
someone sits in the car slowly pressing the brake peddle while you have the brake line open. When finished bleeding the brakes, don't forget to refill the master cylinder.
You have to bleed the brake lines because if there is any air in the lines the brakes will fail. If there is any air in the brake line, when you step on the peddle the air will compress and not transfer the energy to the brake caliper or drum and not stop the car.
Your brake light switch is out of adjustment. Don't know what vehicle you have but most brake light switches are located on the brake peddle lever just above the brake peddle pad.
Brake pads could be worn or lack of fluid in brake funnel

Brake system bleeding is working on hydraulic brake systems. This is when the brake line has air bubbles in the line. You open the bleed screw on the caliper and pump fluid through the lines until all of th bubbles are gone from the system, an air bubble will steal pressure from the brake system and prevent good operation.
Air will compress under pressure, hydraulic brake fluid doesn't. Air in the system will give you a spongy peddle because of that.

You may need to check your brake light switch. It is a small switch located on top of your brake peddle (up on the arm of the peddle). This switch allows the brake lights to come on whenever you push the peddle.
