It is normal to hear abnormal noises when braking on snowy days. The abnormal noises occur when braking on snowy days because the ABS (Anti-lock Braking System) is activated. When you brake hard on snowy days, the ABS activates, and the abnormal noises are a normal phenomenon. Introduction to ABS: The Anti-lock Braking System, abbreviated as ABS. The activation of ABS prevents vehicle skidding caused by sudden wheel lock-up. Function of ABS: During vehicle braking, ABS prevents the wheels from locking up, keeping them in a state of rolling and sliding (with a slip ratio of about 20%), ensuring maximum traction between the wheels and the road surface. Reasons for abnormal braking noises: Abnormal noises may occur due to rust or hard spots on the brake discs or pads, which usually happen when the vehicle first starts moving and may improve after a few more brake applications. Alternatively, the noises could be caused by the suspension system or pressure bearings. In cold and snowy weather, rubber components harden, and when braking, the rubber parts of the suspension system may produce abnormal noises, which should improve after the vehicle warms up. Another possible cause is a malfunctioning brake caliper, which may stick and cause abnormal noises.
Brake noise in snowy weather is actually quite common. Having driven for over a decade myself, every winter when it snows or during snowmelt, some snow or small ice particles get stuck in the brake pads, causing a squeaking sound when braking—just like a rusty door hinge turning. This is completely normal. Melted snowwater seeping in or road debris splashing onto the brake discs can also create noise during friction. If you hear unusual sounds during the first few brakes after driving in fresh snow, don't panic. After driving for about ten minutes, the brake pads will heat up and melt those foreign particles, and the noise may disappear. That said, if the noise persists continuously or is accompanied by a softer brake feel or longer stopping distance, you should be more cautious. It could indicate severely worn brake pads or other mechanical issues, requiring immediate inspection at a repair shop. Safe driving comes first—in winter, be mindful of slippery roads, slow down in advance, and avoid slamming on the brakes. Prevention is key! Regular maintenance and brake system checks are also crucial—don't wait for problems to arise before taking action.
