What Causes the Brake Squealing in Mercedes-Benz E300?
1 Answers
Brake squealing occurs due to reasons such as worn brake pads leading to the backing plate grinding against the brake disc, hardened brake pads, or foreign objects lodged in the brake pads. Below are detailed explanations of the causes: Introduction to Checking the Causes of Squealing: When encountering squealing, the first step is to inspect the thickness of the brake pads, as this is fundamental to ensuring driving safety. Even if the brake pads are not worn thin, they may still produce noise during braking, similar to the sound of grinding against the wear indicator. This is caused by larger metal particles within the brake pads rubbing against the brake disc, resulting in a metal-on-metal friction sound. This is a normal phenomenon and does not indicate any quality issues with the brake pads. Other Causes of Brake Squealing: During the break-in period of a new car, the bedding-in of the brake pads is a crucial phase. Typically, after driving a few hundred kilometers, the braking performance will feel more comfortable. Similarly, newly replaced brake pads also require a break-in period to better integrate with the existing brake disc. Initially, the brakes may feel very stiff, and it usually takes a few hundred kilometers of driving before they start to feel better.
