A brake system is a crucial component of vehicles that allows them to slow down or stop safely. It typically consists of several parts, including the brake pedal, brake lines, and brake pads. When the driver presses the brake pedal, hydraulic fluid is sent through the brake lines to activate the brake pads, which then press against the wheels to create friction. There are different types of brake systems, such as disc brakes and drum brakes. Disc brakes use a flat, circular disc that the brake pads clamp onto, while drum brakes use a cylindrical drum. Both systems are designed to ensure effective stopping power and enhance vehicle safety.
