[0002] The braking system of a two-wheeled vehicle is mainly used to slow down and stop the movement of the vehicle. The braking system converts mechanical energy into heat energy by applying friction to the wheels, thereby slowing down or stopping the movement of the vehicle. The braking system is generally composed of a brake, a brake disc and a brake pad. When the rider steps on the brake pedal of the pedal, the braking system transmits force to the brake. Under the action of the pedal through a series of connecting rods, rods and pistons, the brake applies pressure to the brake disc. The brake disc is installed on the wheel and generates resistance through the brake pad in contact with the brake disc, thereby slowing down the rotation of the wheel. This process can convert the kinetic energy of the vehicle into heat energy and slow down or stop the vehicle.
