Why does the car make abnormal noise when reversing and braking?

[McRiver]

The abnormal noise when braking in reverse is caused by the brake pads. The specific reasons are as follows: Newly replaced brake pads are not fully worn in: Newly replaced brake pads require about 100-200 kilometers to fully wear in. It is quite normal for newly replaced brake pads to produce abnormal noise; Severe wear of brake pads: If the brake pads are severely worn, the vehicle will produce significant abnormal noise when braking, accompanied by insufficient braking force; Uneven texture of brake pads: Some poor-quality brake pads may have areas with harder texture. When these harder-textured brake pads rub against the brake disc, they can produce certain noises.
