What Causes Brake Noise After Snowfall?
2 Answers
There are several reasons for brake noise after snowfall: 1. Corrosion of brake discs or pads: In humid weather or after rain, rust or dirt may form on the brake discs or pads. Applying butter or specialized lubricating oil to the connection between the brake pads and calipers can help. 2. New brake pads: If the car is new or has just had new brake pads installed, the new pads and discs require a break-in period. Noise during braking is completely normal during this phase. 3. Excessive wear of brake discs or pads: Both components are high-wear items that experience friction with each brake application. Over time, this leads to wear, and excessive wear will naturally cause noise. 4. Installation issues: If brake pads are installed incorrectly or the wrong model is used, noise may also occur.
I often drive after snow in winter, and occasionally hear squeaking sounds when braking. This is usually due to the high humidity in snowy weather, where snow or small ice particles get stuck between the brake disc and brake pads, causing noise during friction. In low temperatures, brake materials harden, making them more prone to noise. Thin ice or mud on the brake disc can also cause unusual sounds. I've encountered this a few times—after starting the car, lightly pressing the brakes a few times and driving slowly for a short distance usually grinds away the debris, and the noise disappears. However, if it persists, it might indicate a brake system issue, such as worn brake pads or insufficient lubrication. After snowfall, it's important to promptly clear snow from the wheels to prevent the brakes from freezing. Driving safety is crucial; if you hear unusual sounds, stay calm, maintain a steady speed, and have the brake components checked by a professional as soon as possible, especially since the system reacts slower in cold temperatures, increasing the risk of accidents.
