What Causes the Screeching Metal Friction Sound from the Front Wheels?
1 Answers
The screeching metal friction sound from the front wheels can be caused by foreign objects between the brake disc and brake pads, a damaged brake separation pump, or excessive wear of the brake pads. Details are as follows: Foreign objects between the brake disc and brake pads: Check if there are any wire-like objects entangled around the wheel or the nearby drive half-shaft. Damaged brake separation pump: If the vehicle is not regularly maintained, it can lead to wear of the brake caliper's moving pins, detachment of spring plates, and other issues. Poor caliper resetting can cause prolonged friction of the disc, resulting in abnormal noise. Additionally, check if the brake disc has grooves, as localized friction can also cause noise. Excessive wear of the brake pads: Inaccurate four-wheel alignment can cause significant tire wear during long-distance driving, leading to uneven tire wear and abnormal noise.
