5. Screech! When a driver pushes on the brake pedal, it initiates a process that causes the vehicle to stop in motion. You literally trust automotive braking systems with your life every time you get into a vehicle or cross at a busy intersection, but how does this process work? It begins when the pedal is pushed. At this moment brake fluid is released into the area where the breaking mechanisms are. As the fluid collects, this creates a leverage, which causes a friction to be applied. If the breaking system is functioning properly, this friction will create a force that will cause the wheels to stop and allow you to reach your destination safely.
