Do modern electronic parking brakes release automatically?
2 Answers
For many vehicles equipped with electronic parking brakes nowadays, manual operation is no longer necessary during startup. This is because most automatic transmission vehicles now utilize computer-controlled USB systems. When certain conditions are met (such as throttle application), the brake will automatically release without requiring manual intervention – simply pressing the accelerator pedal will disengage it. Below is an introduction to electronic parking brakes: 1. With auto-hold function activated: In traffic jams, once the brake is pressed and the vehicle comes to a complete stop, the system will automatically engage the parking brake if it determines braking is needed. To start moving again, lightly pressing the accelerator pedal will automatically release the parking brake. 2. Current mainstream electronic parking brakes: These typically use integrated calipers where the motor is incorporated into the brake caliper, eliminating the cable mechanism. Hydraulic braking is used for regular driving, while electric motor braking is employed for parking. This design requires electronic circuitry to interface with the rear brake system, making it relatively more complex.
Having driven for over a decade, switching from an old manual transmission to a modern automatic, the electronic parking brake releases smoothly indeed—just shift to D and lightly tap the accelerator, and it disengages effortlessly, even in stop-and-go traffic. Remembering the old traditional handbrake days, manually pulling the lever to release, sometimes forgetting and ending up with smoking tires. Now, paired with the auto-hold system, parking and starting are worry-free. I recommend checking the manual as models vary slightly, but most mainstream cars feature smart release. Once accustomed, it’s indispensable—safe, energy-efficient, and prevents unnecessary wear.
