The brake system is one of the most important components of a car, responsible for ensuring the safety of the driver and passengers. It is made up of several parts that work together to control the speed of the vehicle and stop it when necessary.
The brakes work by converting kinetic energy into thermal energy, that is, the energy of the movement of the car is transformed into heat through friction between the parts of the brake system.
The main components of the brake system are:
- Brake pads: are the parts that come into contact with the brake disc to reduce the speed of the vehicle. They are made from heat- and wear-resistant materials such as ceramic, metal, or carbon.
- Brake disc: is a circular piece that rotates along with the wheels of the car. Brake pads press against the disc to slow the vehicle.
- Brake drum: is a drum-shaped piece that is inside the rear wheels of the car. Brake shoes press on the drum to slow the vehicle.
- Brake shoes: are the parts that come into contact with the brake drum to reduce the speed of the vehicle. They are made from heat- and wear-resistant materials such as rubber or metal.
- Master cylinder: is the part responsible for pressing the brake fluid through the pipes to activate the brake pads and shoes.
- Brake fluid: is a hydraulic fluid that transmits pressure from the master cylinder to the brake pads and shoes.
There are two main types of brake systems: the disc brake system and the drum brake system. The disc brake system is more common on more modern cars and performs better at high speeds. The drum brake system is more common on older cars and is more efficient at low speeds.
In addition, there are also ABS brake systems (Anti-lock Braking System), which are capable of preventing the wheels from locking in situations of sudden braking. This system works through sensors that monitor the speed of the wheels and adjust the pressure of the brake pads and shoes to avoid locking.

In summary, the brake system is a crucial component for the safety of the car and must be kept in good condition through regular maintenance. It is important to pay attention to signs of wear and tear, such as noise or difficulty in braking, and look for a specialized mechanic to carry out the necessary repairs.
