What Causes Squeaking Brakes in Snowy Weather?
3 Answers
The reasons for squeaking car brakes in snowy weather include: rusted brake discs or pads, new brake pads, excessive wear of brake discs and pads, and assembly issues. Below are detailed explanations: 1. Rusted brake discs or pads: After parking for a long time, especially in humid climates or after rain, some rust or dirt may form on the brake discs or pads. This issue can usually be resolved by driving for a while or by applying butter or specialized lubricant at the connection between the brake pads and calipers. 2. New brake pads: New cars or those with newly replaced brake pads may produce similar noises. New brake pads and discs require a break-in period, and such noises during braking are normal. However, if the noise persists after some time, it indicates a problem. 3. Excessive wear of brake discs and pads: Both brake discs and pads are high-wear components that experience friction with every brake application. Over time, they naturally wear out, leading to unusual noises when excessively worn. Regular inspection and replacement are necessary. Typically, brake pads should be replaced every 60,000-80,000 kilometers, while brake discs last between 100,000-120,000 kilometers. 4. Assembly issues: If brake pads are installed incorrectly or are of the wrong model, they can also cause noise. Reinstalling the brake pads may help. Car owners should always have brake pads installed at professional auto repair shops, especially those who have had them replaced at roadside stalls, as this requires extra attention.
As an experienced driver who frequently drives in northern winters, I've encountered many instances of squeaky brakes during snowy days. This is mainly because the high humidity in snowy weather causes ice and snow to easily stick between the brake discs or pads. When you press the brakes, these ice crystals rub against each other, producing that sharp sound. If it only happens occasionally, there's no need to worry too much—it's usually a normal winter reaction. However, if the sound persists or becomes louder, you should pay attention to the brake system, as it might be due to excessively worn brake pads or accumulated moisture causing metal rust. My previous car once had this issue, and I nearly slid off the slippery road because of it. In such cases, it's advisable to use a flashlight to quickly check the brake area for snow buildup when parked. If the noise continues, head to a repair shop immediately—don't delay, as it could affect driving safety. Additionally, driving slower in snowy conditions and gently applying the brakes in advance can reduce sudden friction noises and protect the entire braking system.
I remember last year during a heavy snow, I drove my kids to school, and the brakes squealed every time I pressed them, which really startled me. This was likely due to the metal contraction of the brake discs and pads in the low temperatures, combined with tiny ice particles from the snow cover, causing loud friction noises. Some might mistake it for a malfunction, but often it's not a big issue—once the snow melts, things return to normal. Still, safety comes first, especially on slippery winter roads. If the noise becomes harsh or persists, it's worth checking if the brake pads are worn or cracked, or if there's rust on the components. I once overlooked this, and my braking distance increased—luckily, I got it fixed in time. Develop good winter driving habits: turn on the AC to defrost before starting the car, and brake gently. It's also wise to carry an ice scraper to clear the wheel hubs or have a technician check the brake fluid during quarterly maintenance to avoid unexpected trouble.
