What Causes Brake Noise in Snowy Weather?
2 Answers
Specific reasons for brake noise in snowy weather: 1. Improper installation of brake pads: When installing new brake pads, the old brake discs were not resurfaced, resulting in a poor fit. Improper installation or failing to resurface the old discs before installing new brake pads will cause the new pads to rub directly against the uneven surface of the old discs, ultimately leading to uneven wear on the new brake pads. 2. Brake system malfunction: There may be inherent defects in the brake system itself, causing the brake pads to only partially contact the brake discs. This increases the pressure per unit area on the brakes, resulting in noise. It is recommended to check components such as the calipers and guide pins. 3. Presence of foreign objects: Foreign objects causing a mismatch in the contact surfaces, leading to noise.
I've been driving for over a decade, and every winter when it snows, I often encounter clicking or squeaking sounds from the brakes. This is mainly because snow and ice cover the surface of the brake discs, causing abnormal friction with the brake pads. On snowy days, the air is humid, and snow splashed from the road onto the brakes can freeze solid in low temperatures, making it particularly easy to hear strange noises when braking after starting the car, and it also affects braking power. I remember last year during heavy snowfall, I almost rear-ended someone because the brakes responded half a beat slower. Later, I learned my lesson—before driving after snowfall, I now check if there's ice buildup on the brakes and carefully clean them with warm water if necessary. Additionally, it's essential to slow down when driving in snowy conditions, especially when turning or going downhill. I recommend regular brake maintenance to prevent these small issues from becoming big problems.
