Why does the brake make a creaking sound on snowy days?

[McNolan]

This is the sound produced when the ABS system is in operation, which is a normal phenomenon. Below is a detailed introduction to the ABS system: 1. When driving on icy or snowy roads, the friction between the tires and the road surface is relatively low. In such conditions, applying the brakes can easily activate the ABS system. ABS stands for Anti-lock Braking System, and almost all household vehicles are equipped with this system. The ABS system prevents the wheels from locking up during emergency braking. If the wheels lock up during emergency braking, the driver will not be able to control the vehicle's trajectory through the steering wheel, leading to a loss of control. If the ABS system is activated during emergency braking, the driver can slow down while maintaining control of the vehicle's direction. 2. In normal situations when braking in an emergency, if your vehicle is equipped with an ABS system, the correct method is to press the brake pedal firmly all the way down. Some drivers tend to pump the brakes in emergencies, which will not activate the ABS system. In an emergency, pressing the brake pedal firmly and completely will trigger the ABS system.
