Reasons for abnormal noise from the rear wheels of the Nissan X-Trail when lightly braking

Introduction to the reasons for abnormal noise from the rear wheels of the Nissan X-Trail when lightly braking: Severe wear of brake pads: This is usually caused by the brake pads reaching the warning line or being completely worn out. The noise is mostly a metallic friction sound and is relatively sharp. If accompanied by a decrease in braking effectiveness, it can be basically confirmed. Abnormal noise caused by brake pad material: Generally, when the brake pad material is relatively hard, this type of noise is more likely to occur. Brake pads with softer materials rarely produce this type of abnormal noise. However, softer materials wear out faster, and the corresponding replacement cycle is shorter than that of harder materials. Improper installation of the brake system: This can cause abnormal noise. It is recommended to visit a 4S shop or repair shop for inspection as soon as possible.
Over the years of driving my Nissan Qashqai, the issue I've encountered most frequently is a squeaking sound from the rear wheels when lightly applying the brakes. At first, I thought it was due to the car aging, but later discovered that even new cars have this problem. The main reason is the accumulation of dust or tiny metal particles on the brake pads, which causes friction against the brake discs and produces noise when lightly braking. Some Nissan models use harder materials, which are more prone to scratches and noise. I've also noticed that the issue is more pronounced on rainy or humid days—the first few kilometers after the brake discs rust, the friction from rust particles makes the noise even louder. If the brake pads are improperly installed, loose, or have gaps, the noise becomes a constant companion. It's advisable to rinse the wheel hubs regularly during car washes to reduce dust buildup. If the noise persists, it's best to have a professional shop inspect and replace the brake pads. After all, safety comes first—while a light squeak may seem minor, it could signal other underlying issues.
