Winter Brake Noise
2 Answers
The reasons for brake pad noise in winter: It may be due to the prolonged exposure of the brake pads and brake discs to cold, forming ice condensation at the contact points. When the car starts, slight noise may occur as the ice condensation is eliminated. This is not a brake malfunction noise but a normal phenomenon. Reasons for brake noise: 1. If it's a new car, the brake pads and brake discs are still in the break-in period, which may cause a slight hissing sound. This is normal. 2. There is a foreign object between the brake pad and the brake disc. 3. On rainy days or when there is water in the brake disc, the brake pads and brake discs are relatively damp. At low speeds, the brakes may produce a vibration-like humming noise, which is normal. 4. The brake disc and brake pad may stick together due to rust, causing noise. After driving in the rain, if the car is left unused for several days, the brake disc and brake pad may rust and stick together, resulting in noise when starting the car again.
I've been driving in the north for several years, and every winter, the brakes make a harsh screeching sound, like metal grinding, which is really annoying. Usually, the cold weather makes the brake pads harder and more brittle. If there's snow or ice on the road, a thin layer of ice forms on the brake discs, causing constant noise when braking. My experience is to warm up the car for a few minutes before driving in the morning, then drive at low speed for a while to let the brake system warm up before accelerating normally. If the noise persists for more than a week, it's advisable to check the wear of the brake pads and replace them if necessary. Don't delay, as it could damage the rotors and lead to bigger issues. Remember to clean brake dust regularly, as it tends to accumulate and harden in the brake areas during winter. During seasonal maintenance, ask the technician to pay special attention to the brake system to avoid minor problems turning into major repairs.
