Why does my brake pedal stay on the floor?

How do I check my brake pedal Reserve?

Brake Pedal Reserve is a measurement from the floorboard of the vehicle to the TOP of the brake pedal when the brakes are applied. Check the brake pedal reserve distance with the engine running. This allows the power brake system to operate. Apply the brakes with a moderate force (about 20 lbs of force).

How far should your brake pedal go down?
