A brake system is a crucial component in vehicles that allows them to slow down or stop safely. It typically consists of several parts, including the brake pedal, brake pads, rotors, and hydraulic lines. When the driver presses the brake pedal, it activates the system, which creates friction to reduce the vehicle's speed. There are different types of brake systems, such as disc brakes and drum brakes. Disc brakes use a flat rotor and brake pads, while drum brakes use a cylindrical drum and shoes. Both systems are designed to ensure effective stopping power and enhance vehicle safety.
