What to Do When There's Abnormal Noise When Braking at Startup in the Sunny?

[Cory]

Here are the specific reasons for abnormal brake noise when braking at startup in the Sunny: 1. When installing new brake pads, the old brake disc was not polished, resulting in improper fit. Improper installation or failure to polish the old disc before installing new brake pads will cause the new pads to directly rub against the uneven surface of the old disc, ultimately leading to uneven wear of the new brake pads. 2. There may be a defect in the brake system itself, causing the brake pads to only partially contact the brake disc. This increases the pressure per unit area on the brakes, resulting in abnormal noise. It is recommended to check components such as the caliper and guide pins. 3. Foreign objects may be present, causing the contact surfaces to not fit properly and resulting in abnormal noise.
