The invention provides a braking system for a vehicle, a wheel end braking device and the vehicle. The brake system comprises a main controller and at least one wheel end brake device, each wheel end brake device comprises a brake motor, a brake motor controller and an actuator, and the brake motor controller is used for controlling the brake motor to output brake torque so as to drive the actuator to output friction brake force to a brake disc of the vehicle. The brake motor controller is used for responding to a brake torque signal output by the main controller, firstly controlling the brake motor to output a first brake torque and then controlling the brake torque output by the brake motor to be reduced to a second brake torque, the second brake torque is smaller than the first brake torque, and the second brake torque is smaller than the first brake torque. The difference value between the friction braking force output by the actuator driven by the first braking torque and the friction braking force output by the actuator driven by the second braking torque is smaller than a preset value, and therefore the braking performance of the braking system is guaranteed, and meanwhile a braking motor is prevented from being overheated.
