The **foot brake** is an essential component in vehicles, designed to **reduce speed or stop the vehicle** safely. This brake acts on **all the wheels of the car**, not just the front or the driving wheels.

- When the brake pedal is pressed, a force is transmitted through a special fluid called **brake fluid**. This fluid carries the force to the **pads or shoes**, which are the elements that actually brake the wheels by rubbing against other components.

- It is important to **brake smoothly and in a controlled manner**, adapting to the road conditions to prevent the brake system from overheating and losing effectiveness. In emergency situations, the use of the brake may vary depending on whether the vehicle has an **ABS system** or not.

Therefore, the foot brake is designed to act on the **four wheels** of the vehicle, ensuring balanced and effective braking.
