What are the key components of a bike brake system and how do they work together to ensure effective braking?

The key components of a bike brake system are the brake lever, brake cables, brake calipers, brake pads, and the braking surface (usually the rim or disc). When the brake lever is squeezed, it pulls the brake cable, which in turn activates the brake calipers. The calipers then press the brake pads against the braking surface, creating friction that slows down the bike. All these components work together to convert the mechanical force from the rider's hand into stopping power for the bike.
