What Causes the Electronic Parking Brake to Not Release?
1 Answers
Possible causes include failure of the parking brake ratchet mechanism or motor malfunction. Below is relevant information about electronic parking brakes: 1. Introduction: The professional term for the parking brake is auxiliary brake, which operates differently from the main brake system. It uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. A return spring is used in conjunction with the parking brake—when the parking brake is engaged, the spring stretches; when released, the spring returns to its original length. Prolonged use of the parking brake can cause the spring to deform. 2. Precautions: Activating the electronic parking brake requires pressing the brake pedal first, along with a response time for the button (to prevent accidental operation). Additionally, the motor operation time is relatively long, approximately 0.5 seconds.
