【Abstract】This paper focuses on the problem of a pure electric vehicle producing an abnormal sound when the brake pedal is depressed. Through cross validation of parts，bench simulation test，dismantling and analysis of faulty parts and dimensional measurement of parts，it is found that the electric brake booster causes the abnormal sound in the braking. This paper confirms the cause of the abnormal sound in the electric brake booster and effectively solves the problem to improve product quality.
