What does it mean when the electronic parking brake makes a squeaking sound after being engaged?

It is normal for the electronic parking brake to make a squeaking sound after being engaged. The electronic parking brake is a technology that uses electronic control to achieve parking braking. Its working principle is the same as that of a mechanical handbrake, and there will be sounds from the motor when engaging and releasing the electronic parking brake. Automobile brakes can be divided into the following two situations: 1. Manual handbrake: During this process, special attention is required. If the car speed is too high, pulling the handbrake forcefully may cause the car to overturn. Therefore, to avoid accidents, it is essential to pull the handbrake gently when the speed is high to prevent overturning. 2. Electronic parking brake: In addition to the manual handbrake, there is also an electronic button-type parking brake, which is much more stable compared to the manual type. This electronic parking brake controls the braking force through the vehicle's computer to achieve braking. As another braking method, it does not rely on the hydraulic braking system. Therefore, when the foot brake is ineffective, the electronic parking brake is very useful.
