How to Deal with Electronic Parking Brake Malfunction?
2 Answers
Electronic parking brake malfunction can be addressed by: 1. Restarting the vehicle for a retry; 2. Visiting a repair shop or 4S store for detailed inspection or repair. The electronic parking brake is a technology that achieves parking braking through electronic control, sharing the same working principle as the mechanical handbrake—both utilize the friction between the brake disc and brake pads to control parking braking. However, the control method has evolved from the traditional mechanical handbrake lever to an electronic button. Also known as the Electronic Parking Brake (EPB) system, it integrates the temporary braking function during driving with the long-term braking function after parking, achieving parking braking through electronic control. Its advantages include saving the space occupied by mechanical handbrakes and creating a larger central control space.
Last time I encountered an electronic handbrake malfunction, the light kept flashing red and the car couldn't move. I was so scared that I immediately turned off the engine and pulled over to wait a few minutes before trying to restart the system. If that didn't work, I checked the manual to see if there were any reset steps for simple button operations, but avoided forcefully pulling to prevent hardware damage. Common causes might be a stuck switch or poor wiring contact - humid weather can also easily cause issues. When I took it to the 4S shop for inspection, they found the sensor was dirty and it worked fine after cleaning. Professional repair is more reliable. Remember safety first - don't drive when there's a malfunction, call for rescue and a tow truck. During regular maintenance, have technicians test the handbrake function as prevention. Keeping the interior dry can reduce failure frequency. Handling such minor issues properly can extend the vehicle's lifespan.
