Reducing vibration and noisy product

When the car runs in low speed, rotor brake of contact will cause vibration, sometimes it happens sharp noise, which not effects the performance of the brake, but it will lead unnecessary replacement of brake, gasket materials and other components. If installing a simple piezoelectric ceramic brake in the brake position in the car, the piezoelectric ceramic will exert a certain frequency to the fast support internal vibration, the frequency will restrain the vibration of sharp noise, thus to keep stable while changing the temperature, humidity and brake system in the condition of normal wear.
