What causes the squealing sound when pulling the electronic handbrake?

[LeConnor]

The reason for the squealing sound when pulling the electronic handbrake is that the brake pads are severely worn and have reached the position of the warning indicator. Introduction to Brakes: 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 general principle of braking involves fixing a wheel or disc on the high-speed shaft of the machine and installing corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. The braking device, also known as a decelerator, is a mechanical device that can slow down the vehicle speed. Classification of Brakes: Drum brakes, advantages of drum brakes, disadvantages of drum brakes, disc brakes, etc.
