What does it mean to release the handbrake?

[DeMary]

Releasing the handbrake refers to the action of disengaging the mechanical handbrake when starting the car, otherwise it can easily cause wear and tear on the brake system hardware and lead to the car stalling. Generally speaking, driving with the handbrake engaged causes more damage to the brake components the faster the speed, and it can also cause some damage to the tires. Below is some related information: 1. Parking Brake: Commonly known as the handbrake, its function is to provide resistance to the car when parked, preventing it from rolling. The parking brake, whether manual or the parking gear in an automatic transmission, locks the drive shaft or rear wheels. The force applied by the parking brake is much less than that of the service brake, just enough to prevent the car from rolling on a slope. 2. Auto Hold Function: Traditional handbrakes require the driver to manually release the brake or skillfully coordinate the throttle and clutch for a smooth start on a slope. The AUTOHOLD auto hold function, however, uses a slope sensor to provide precise braking force through the controller. During startup, the parking control unit calculates information from sensors such as the clutch distance sensor, clutch engagement speed sensor, and throttle pedal sensor. When the driving force exceeds the rolling resistance, the parking brake is automatically released, allowing the car to start smoothly.
