What is the difference between a handbrake and an electronic parking brake?
3 Answers
The differences between a handbrake and an electronic parking brake are: 1. Space occupation: The handbrake occupies more space; the electronic parking brake is aesthetically pleasing, convenient, and space-saving. 2. Functionality: The handbrake can be used for drifting maneuvers; the electronic parking brake cannot perform drifting maneuvers. 3. Control system: The handbrake is not affected by the battery; when the battery fails, it can cause the electronic parking brake to malfunction or become impaired. The professional term for the handbrake is auxiliary brake, which differs in principle from the main brake. It uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Long-term use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, prolonged use will reduce its effectiveness. 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 of which apply braking force by tightening the rear brake shoes via a cable.
Back when I first started driving, the handbrake in older cars required pulling a lever or stepping on a pedal with force—it was all about manually tightening the brake cable. Parking on steep slopes always made me worry about rolling back, so I had to double-check repeatedly. Electronic parking brakes are much easier; just press a button in newer cars, and an internal motor automatically tightens the brake pads, working like a smart assistant. I especially love the added automatic features, like auto-hold when braking hard at a red light, which releases upon pressing the accelerator—effortless and perfect for preventing fatigue in city traffic jams. However, manual handbrakes are simpler and cheaper to maintain; you can even replace the cable yourself. If an electronic parking brake fails, repairs are costly and time-consuming. Overall, electronic parking brakes represent the future, making driving safer and more convenient.
Having driven for many years, I believe the difference lies in reliability and ease of operation. The handbrake is a purely mechanical device with a simple and durable structure, rarely malfunctioning, and it can still function even in extreme situations like a dead battery. As an experienced driver, I trust its auxiliary role in emergency braking. The electronic parking brake operates via a button, with internal electronic systems automatically executing the function, providing more stability on slopes without rolling back, and supporting smart features like automatic release. However, the downside is that if the electronic module or sensors fail, the parking function may become ineffective, and repair costs are higher. From a safety perspective, the electronic parking brake reduces human error, especially being more reliable in rainy or snowy conditions. I recommend choosing the electronic parking brake for daily driving, but the handbrake is more practical for off-roading or long-term parking.
