What Causes the Brake to Suddenly Become Hard and Unable to Start?

The reason the brake suddenly becomes hard and the car cannot start is that the steering wheel safety lock has automatically engaged. In this case, press the brake pedal and gently turn the steering wheel left and right to start the car. The car steering wheel is a wheel-shaped device that controls the direction of travel. It is connected to the steering shaft via splines, converting the force applied by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering shaft. The function of the brake is to reduce speed or bring the vehicle to a stop. Its working principle is to convert the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and the brake drum, as well as between the tires and the ground, thereby slowing down or stopping the vehicle.
