What Causes the Squeaking Sound When Braking at Low Speed?

[CalebFitz]

When braking, a squeaking sound occurs, especially after prolonged parking or in damp weather or after rain. This is due to rust or dirt on the brake pads or brake discs. Clean them thoroughly and apply butter or specialized lubricant at the connection between the brake pads and the brake calipers. Below is more detailed information: Content 1: If there is a noticeable squeaking sound when braking at low speed, this is caused by newly replaced brake pads. Don't worry; the sound will disappear automatically after a break-in period. Content 2: Excessive wear on the brake discs and brake pads can also cause abnormal sounds. Brake discs and pads are essentially high-wear components, as they constantly rub against each other during braking. Over time, this friction naturally leads to wear. When the wear becomes excessive, it will naturally produce noise. At this point, new brake pads need to be replaced.
