What is the function of the handbrake?

[Beckett]

The handbrake, also known as the parking brake, functions by providing resistance to the car when parked, locking the drive shaft or rear wheels to prevent the vehicle from automatically sliding when left unattended on flat ground or slopes, thereby avoiding traffic accidents. Precautions for using the handbrake are as follows: 1. Do not pull the handbrake too tightly: Many modern cars have spring-loaded handbrakes with multiple positions. The higher you pull the handbrake, the more tension is applied to the spring. Therefore, pull it just enough to prevent the car from moving, and avoid pulling it to the maximum position, as this helps extend the handbrake's lifespan. 2. Always release the handbrake when starting the car: Remember to press the button and ensure it is fully lowered. Many people forget to release the handbrake when starting the vehicle, which can cause damage to the handbrake.
