What are the reasons why the Volkswagen handbrake cannot be released?

Introduction to the reasons why the Volkswagen electronic handbrake cannot be released is as follows: 1. Electronic handbrake system malfunction: The electronic handbrake is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake, both achieving parking braking control through the friction generated between the brake disc and brake pads, except that the control method has changed from the previous mechanical handbrake lever to an electronic button. If there is a problem with the electronic handbrake system, a maintenance computer should be used for detection. If there is a fault code, clear the fault code. If there is no fault code, the battery cable can be removed, left for about 5-10 minutes, and then reinstalled. 2. Parking directly after washing the car in winter: This causes the brake disc, brake pads, and brake caliper to freeze together. Pouring a pot of boiling water over them can thaw them out.
I've been driving Volkswagen cars for over a decade and have encountered situations where the handbrake gets stuck and won't release, which is quite common. The main reasons are the brake cables getting rusted or jammed by dust, especially in humid or cold weather when water seeps in and freezes, making it immovable. The rear brake shoes might also stick together, and the springs fail to bounce back. Occasionally, the button or control lever malfunctions, and for electronic handbrake models, the control module can act up. Last time my car had this issue, I tried forcing it open and almost damaged the components, but luckily I went to the repair shop in time. The technician sprayed some lubricant and cleaned it up, and it was fine. If it's severe rust, parts may need replacement. I suggest you don't delay and get it fixed before driving—safety first. Regularly check the handbrake system during maintenance to prevent dust and corrosion, which can avoid a lot of trouble.
