Car brakes are a system of components that work together to slow or stop a vehicle. The main components of a car's brake system are the brake pads, the brake calipers, and the brake discs or drums. The brake pads press against the brake discs or drums when the brakes are applied, which generates friction that slows or stops the vehicle. There are several different types of brakes, including disc brakes, drum brakes, and ABS brakes. Disc brakes are the most common type of brakes, and they are composed of a brake caliper, brake pads, and a brake disc. Drum brakes are less common, and they are composed of a brake drum, brake shoes, and a wheel cylinder. ABS brakes are the most advanced type of brakes, and they are designed to prevent wheel lockup during hard braking.
