Why does the brake make noise when the car just starts?

[Ingrid]

The reasons for brake noise when the car just starts are: 1. There are metal particles or small gravel between the brake pads and brake discs; 2. Excessive wear of the brake discs or brake drums; 3. The brake pads are too hard; 4. Rust on the brake calipers; 5. The handbrake cable is not flexible; 6. Slow return of the brake master cylinder. The solutions for brake noise when the car just starts are: 1. Check if there is a problem with the lubrication of the top rubber or buffer rubber of the shock absorber; 2. Break in new brake friction pads; 3. Replace the brake pads in time; 4. Clean foreign objects on the surface of the brake discs. Braking, also known as deceleration, refers to the action of stopping or reducing the speed of running locomotives, vehicles, other transportation tools, or machinery.

Every time I start the car in the morning, the brakes make a squeaking noise, and I often encounter this situation, especially during the humid season or after rainy days. This is because the car has been parked overnight, and a layer of moisture or slight rust has formed on the surface of the brake discs and pads. When I start driving and apply the brakes, the friction causes the noise, but after a few minutes of driving, the temperature rises, the rust wears off, and the noise disappears. It's generally not a big issue. However, if the noise persists or is particularly harsh, it could be due to uneven wear of the brake pads, foreign objects stuck in them, or aging that requires replacement. As an experienced driver, I recommend regularly checking the thickness of the brake pads and cleaning the system, such as inspecting the discs and pads monthly for cracks or dirt. Prevention is always better than dealing with a malfunction. Don’t overlook this—brakes are crucial for safety, especially before long trips, make sure everything is in proper condition.

As a regular car owner, the squeaky noise when braking after just buying the car really gave me a scare. After consulting, I learned that the reason is usually quite simple: the brake discs have dew or rust when cold, causing a squeaking sound during friction. After driving for a while and warming up, the noise naturally stops, so there's no need to panic. However, if it squeaks loudly every time, the brake pads might be worn thin or not installed securely. I've noticed that parking in the garage after rainy days makes this more likely, and a simple fix like drying the brake discs can help. I recommend keeping an eye on any unusual noise changes and getting a quick check at the shop if possible to ensure worry-free driving. Similar startup issues aren't uncommon, and a little maintenance can prevent trouble.

Brake noise when starting the car is mostly normal, especially caused by rust on the brake discs in cold or humid weather, which stops after some friction. If the noise persists or there's a metallic sound, check for damaged parts. Simple prevention tips: park in dry places to avoid moisture buildup; address any issues promptly to ensure safety.
