What is the Difference Between a Manual Handbrake and an Electronic Parking Brake?
2 Answers
Electronic parking brakes and manual handbrakes operate on the same principle. The difference lies in the fact that electronic parking brake systems replace manual operation with mechanization, whereas handbrakes require manual operation. Below are detailed explanations regarding automotive braking systems: 1. Braking: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transportation tools, or machinery. The braking device is a mechanical deceleration device that slows down the vehicle, also known as a retarder. 2. Braking System: The braking system consists of a control system, a hydraulic system, and a power assist system. The control system includes components such as the pedal and handbrake. The hydraulic system comprises hydraulic fluid, a brake pump, and hydraulic lines. The power assist system consists of a vacuum booster pump. The electronic control system includes an ABS pump, ABS sensors, and an ABS computer. The execution system is made up of brake calipers, brake pads, and brake discs.
After driving for so many years, I feel the main differences between handbrakes and electronic parking brakes lie in the operation method and user experience. The traditional handbrake is a mechanical lever that uses cables to pull the rear calipers and lock the tires. You need to exert some force to pull it up every time you park, especially in winter when it feels particularly stiff. In contrast, the electronic parking brake is much more effortless—just press a button, and the computer controls the motor via the ECU to achieve braking. The most convenient part is that many electronic parking brakes are linked with auto-hold (AUTO HOLD), automatically engaging when you press the brake pedal hard at a red light and releasing when you press the accelerator to start moving. However, mechanical handbrakes are cheaper and more durable, with affordable adjustments and part replacements, while electronic components can be expensive to repair if they fail. My new car now has an electronic parking brake, which saves effort, but when driving older cars, I still miss the tangible mechanical feel.
