How to Solve the Problem of Electronic Parking Brake Not Releasing?
2 Answers
Electronic parking brake not releasing can be addressed by: 1. Method one: First, fasten the seat belt, start the car, shift to D gear, and lightly press the accelerator. Usually, the locked state of the electronic parking brake will automatically release. 2. Method two: If the above operation still fails to release the brake, it indicates a fault in the electronic parking brake system, and it is recommended to visit a repair shop for inspection. Extended content: The electronic parking brake 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 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.
When the electronic parking brake won't release, I usually first check the battery level. In older cars, battery aging and insufficient voltage can easily cause system lag. Use a multimeter to test the battery voltage—if it's below 12V, recharge or replace it. Next, try restarting the vehicle: turn off the engine, lock the car for a few minutes, and then restart. This can reset the electronic module. Also, make sure to fasten your seatbelt and press the brake pedal firmly while operating the button. Sometimes, a blown fuse can cause this issue—open the fuse box near the driver's seat and check the EPB-labeled fuse for damage, replacing it if necessary. If the cable connections are loose or a sensor is faulty, it's more complicated; you can check the connections by opening the trunk. If the problem persists, don't force it—safety first. Park on the roadside and call a professional tow truck. Regular maintenance of the battery and electronic systems can prevent such issues. I replace my car's battery every three to five years to minimize these kinds of failures.
