Why Does the New Car's Brake Squeak?

[Rhonda]

The reasons for the squeaking sound of a new car's brakes are: 1. Severe wear of the brake disc; 2. Brake pad warning; 3. Use of inferior or overly hard brake pads; 4. Presence of sand or foreign objects between the brake pad and brake disc. Brake pads, also known as brake linings, are critical safety components in a car's braking system. The effectiveness of all braking is decisively determined by the brake pads. Methods to check brake pads: 1. Check the thickness: A new brake pad is generally about 1.5cm thick, and the thickness gradually decreases with use due to friction; 2. Listen for sounds: If a slight braking action is accompanied by a metallic scraping sound or squealing (which could also be due to the initial break-in of newly installed brake pads), the brake pads must be replaced immediately; 3. Feel the pedal: If pressing the brake pedal feels unusually strenuous, requiring deeper depression to achieve the usual braking effect, or if the pedal position feels noticeably lower during emergency braking, it may indicate that the brake pads have largely lost their friction and must be replaced immediately.
