How to resolve an EPB malfunction?
2 Answers
EPB malfunction resolution method: Press the foot brake down while simultaneously pressing the handbrake down, hold for about 20 seconds, then lift the handbrake up to release. EPB stands for Electrical Park Brake, which is the electronic parking brake system commonly referred to as the electronic handbrake. EPB calculates the slope using a built-in longitudinal acceleration sensor in its computer, thereby determining the vehicle's tendency to slide downhill due to gravity. The computer then applies braking force to the rear wheels via an electric motor to counteract the sliding force, allowing the vehicle to remain stationary on a slope.
When the electronic parking brake fails, I have my own troubleshooting routine. I usually start with simple checks: confirm if the vehicle is turned off, then restart it a few times—many minor issues can be resolved with a reboot. If there's no response, check whether the battery has sufficient charge, as an aging battery often causes system failures. You can use a multimeter to test the voltage or listen for changes in sound during startup. Keeping a manual parking brake release cable in the trunk is crucial; gently pulling it can temporarily release the brake. If all these steps fail, never force the brake pads, as this can easily damage more components—promptly contact a professional for repairs. Having driven multiple car models, I always reflect on maintenance habits whenever encountering electronic failures. Regular system diagnostics at authorized service centers can prevent 90% of issues—safety comes first.
