Why can't the electronic parking brake of Jetour X70 be released?

[McMia]

There are several reasons why the electronic parking brake of Jetour X70 cannot be released: Plastic deformation of the steel wire: Long-term use of the parking brake by the driver while driving can cause plastic deformation of the steel wire. Since the deformation of the steel wire is irreversible, prolonged use will reduce its effectiveness, increase the travel of the parking brake, and necessitate replacement. Deformation of the return spring: There is also a return spring used in conjunction with the parking brake. When the parking brake is engaged, the electronic parking brake spring is stretched; when the parking brake is released, the spring returns to its original length. With long-term use of the parking brake, the spring can also undergo corresponding deformation.
