How to Deal with Electronic Parking Brake Failure?
2 Answers
Electronic parking brake failure is an issue that car owners cannot resolve on their own and requires repair at a 4S shop. The electronic parking brake, also known as the electronic handbrake, is commonly equipped in many mid-sized and compact cars. Unlike traditional mechanical handbrakes, the electronic handbrake system features two handbrake motors on the rear wheels. When the electronic handbrake button near the gear shift is pressed, these motors clamp the brake pads, preventing the car from rolling. The electronic parking brake is located on both rear wheels. If it fails, the car needs to be lifted, and the rear wheels must be removed for repair.
Having issues with the electronic parking brake can be really frustrating—I’ve experienced it myself. That time, after parking, I couldn’t release it no matter what, and the display showed a red light. First, I restarted the engine to let the system initialize, but it didn’t help. Then, I checked the fuse box, located the corresponding fuse, and pulled it out to see if it was blown—sometimes an overload can burn it out. If the fuse was fine, it might have been a sensor or circuit board failure. Never force the car to move, as it could damage the braking system or even the tires. In the end, I called a tow truck to take it to the 4S shop, where the technician diagnosed it as a software glitch with their computer and fixed it by flashing a new program. A reminder to everyone: during regular maintenance, ask the technician to check the wiring of the electronic systems to avoid similar issues.
