Brake squeal is a common issue that can occur due to various factors, and addressing it effectively is crucial for maintaining optimal braking performance and ensuring driver safety. Replacing worn pads or using anti-squeal shims is a proactive approach to mitigate this problem.

Worn brake pads can generate noise because they lose their material and become less effective at adhering to the rotor surface. This can cause vibrations, leading to squeaking or squealing during braking. When worn pads are replaced, the new pads usually come with better friction material that can effectively grip the rotors without producing noise.

Additionally, anti-squeal shims are specifically designed to dampen vibrations that can lead to squeal. These shims are placed between the brake pad and the caliper, acting as a buffer that absorbs vibrations and reduces noise. Their use is recognized as a practical solution to address squeal without compromising braking efficiency.

Therefore, opting for replacing worn pads and employing anti-squeal shims is a well-recognized method in brake maintenance that not only helps to reduce undesirable noise but also enhances the overall performance and longevity of the braking system.
