Your car could be losing brake pressure because you have a bad ABS control module. It also could be a bad brake booster.

A brake line may be broken missing or loose.
What is the name of the small rubber piece that is located under the brake pedal that turns off the tail lights?
The part of the car that turns on the brake lights when you apply pressure to the brake pedal is called the brake switch. Releasing pressure from the pedal causes the brake switch to break its electrical contact, turning off the lights.
What if my car won't turn on but the brake lamp turns on?

What happens in the brake system of a car from the time a driver steps on the brake pedal to the time the car stops?
First the driver puts pressure in the foot brake, which then pushes a small piston, the piston then exerts pressure in the brake fluid. Then the increased pressure is transmitted through the fluid in the brake lines to a larger piston within the wheels of the car. Each piston pushes in a brake pad which the rubs against the brake disc, and the wheels motion is slowed down by the force of friction.
What will be the standard intensity of pressure in brake drums of car?

Melvin is an experienced driver He knows that the more pressure he applies to the brake pedal the faster his car will stop?
Braking distance is a function of pressure applied to the brake pedal.
Why does your car have to have brake fluid?
A car has to have brake fluid to allow for the effective operation of the brakes to stop the car. When we apply pressure to the brake pedal, brake fluid, which is largely incompressible, will transfer that pressure to the pistons that operate the in the calipers or the pistons that operate the brake shoes. Further, the fluid must be of the correct type for the system in which it is used. The continued safe operation of the brakes may be compromised by the wrong fluid.
Why does the car's electrical turn on when the brake pedal is depressed and the car is not running?
It turns the rear brake lights on as a safety feature. The brake pedal is pushed in, causing the fluid to move forward in the brake cylinder,activating a brake light switch. Even if the vehicle is off, the lights will still come on.
