Why does the brake make a rattling sound on snowy days?
1 Answers
When the brake makes a rattling sound on snowy days, it is the sound produced by the ABS system in operation, which is normal. When driving on icy or snowy roads, the friction between the tires and the ground is relatively low, making it easy to trigger the ABS system when braking. ABS, or Anti-lock Braking System, is equipped in almost all household vehicles. The ABS system prevents wheel lock-up during emergency braking. If the wheels lock up during emergency braking, the driver cannot control the vehicle's trajectory via the steering wheel, leading to loss of control. When the ABS system is activated during emergency braking, the driver can slow down while maintaining control over the vehicle's path. The ABS system keeps the wheels in a state of rolling and sliding, allowing the driver to continuously adjust the vehicle's direction to avoid obstacles.
