What Causes Brake Noise When the Car Just Starts?
2 Answers
If the car has been parked for a long time, especially overnight, and produces abnormal noise when braking after starting, but the noise disappears after driving for a while and then braking again, this is caused by high air humidity and moisture on the brake pads, which can be ignored. If there is abnormal noise every time you brake, it is due to severe wear of the brake pads. Here are some braking techniques: Emergency braking: Some vehicles are not equipped with ABS, so it is not recommended to apply full braking force at once. Instead, brake in two separate steps to prevent the wheels from locking up, which could cause skidding and loss of steering control. Braking in rainy conditions: When driving on wet roads, avoid suddenly pressing the brake pedal or turning the steering wheel sharply. After passing through a waterlogged area, it is best to gently press the brake twice to use inertia and friction to remove water from the brake discs, preventing brake failure during sudden braking.
When starting the car, there's a strange noise from the brakes. As an experienced driver, I've seen this many times. It's mostly due to rust or dew on the surface of the brake pads. After the car sits overnight, moisture accumulates, causing a squeaking sound when you brake at the start. If the noise disappears after driving a short distance, it's just a temporary issue and nothing to worry about. However, if it happens frequently in humid weather, it's advisable to check the wear on the brake pads. If they're too thin, they need to be replaced. I get my brake system thoroughly inspected at a professional shop every two years to ensure the discs are smooth and free of grooves. Additionally, after parking, you can use a fan to gently blow on the brake area to remove moisture. After all, safety comes first. Don't ignore minor noises; if they persist, they need to be addressed.
